Reviving my BROKEN PRUSA with NEW Duet 3 Mini

[@CNCKitchen]

Marlin or Reprap Firmware? What do you prefer? Don't forget to share this video on Facebook, Reddit, Twitter, and other platforms!

[@antonrickert9427]

I personally use Marlin in combination with octoprint, but I never tried RepRap.

[@harjoat]

Klipper with Mainsail.

[@nimeq]

Reprap Firmware by far, not necessarily because of the firmware explicitly, but the duet+reprap firmware combination is just so easy to work with.

[@jwunder246]

Klipper with fluidd

[@certified-forklifter]

Waiting for the Klipper guys to spam this section :D I never got around to try it, but it seems to be cool.

[@elliotfoster4733]

Cheap SKR boards + raspberry pi + klipper is what has replaced my Duet boards (which replaced my smoothie boards, which replaced my RAMPS). For a while I even ran the Duet web interface (DWC) with klipper but have since moved to Fluidd for easier installation/maintenance. I can understand that it's not for everyone, but I've found it to work pretty well, and it saves a decent amount of money over the very nice but very expensive Duet boards.

[@MrCcfly]

lol kliper is only good on 8bit boards on 32 it's same

[@jeffwitz8556]

seems really cool, there are duet clone that allows to have a reprap firmware with low-costs. Do you use a klipper feature that you won't find on reprap ?

[@warmesuppe]

@@jeffwitz8556 input shaper?

[@Olof123]

@@MrCcfly nope lol, but it can make 8 bit boards better but some printers need 32bit and Klipper.

[@elliotfoster4733]

@@jeffwitz8556 It's not so much about features as being able to use the same firmware on just about any board. I was able to add klipper to my Ender 3s and have a nicely integrated network-accessible web interface (Fluidd) that I much prefer to Octoprint (which is good in its own way)

[@SuicideNeil]

Heh, print a mobile-phone holder for the front of the machine so that you can pretend it still has a screen built-in when you're tweaking the settings...

[@jirikolda3709]

Or use old phone

[@Cronin149]

My Prusa Clone Marlin board died and the replacement was DOA. I went with Duet Wi-Fi and it was the best move I ever made. There is a learning curve but the output quality and control is amazing. Great video.

[@gertbenade3082]

I am currently converting a XYZ Da Vinci Mini with a Duet2 board and found your video very informative. Keep up the good work and thank you for a great channel!👍 Gert South Africa

[@DenisOvod]

Thanks for the video! I'm very interesting in seeing a video about reprap vs klipper comparison.

[@dakotac.9037]

Hey great video man! If you are thinking about needing a screen interface aside from using your phone, I recommend looking into getting an old android tablet and printing a front mount where the old LCD use to be. My old android tablet even had wireless charging, so I hooked up a cheap wireless charger to the 5v line and now it charges while docked on the printer.

[@garramiro]

i have been using my phone as the interface for the printer (own a duet wifi) for almost 3 years and i absolutely love it.

[@MrHristoB]

Comprehensive and very helpful. I still use my good old trusty Mk2, just recently reprinted all parts with high quality PETG, fitted new bearings and 2208 drivers on the good old Mega/Ramps combo, just went for ramps 1.6. This thing has never let me down..

[@nhansen7231]

I wish you posted this last week. Same thing happened to my mk2 and I bought the Rambo mini, I didn't know how easy it would be to upgrade it

[@CNCKitchen]

Sorry 😅

[@darknessblades]

if you're in the EU you have 14 days return period without giving any reason. depending on the item you are even allowed to test it, and return it without reason.

[@notsonominal]

"easy" is a relative term though..

[@warmesuppe]

excellent choice with the Duet! 👌😎 and nice video

Glad you liked it!

[@avejst]

Great Video as always Im jumping to the klipper FW soon Very mutch inspired of the Voron way of duing things Thanks for sharing your experience with all of us :-) 👍

[@christophmuller3511]

There is also a share of Voron’s running on RRF

[@inakidb]

from your past video, I get notice Voron, I never see them before, so thanks to you, my next printer will be Voron 2.4 with klipper.

[@matthewweinberger7023]

its nice to see old printers revived and improved

[@CNCKitchen]

Totally. Really considered throwing it away but that would have been a pity.

[@darknessblades]

The only thing i mod about my printer {Anet A9} are structural mods, smoothers and a better mosfet. Upgrading the board itself is quite useless as it would cost more than the printer itself costed me. {aliexpress brand sale: for about 70$ before coupons i got the printer} Which is a steal if you see what the Anet A9 can do

[@andy_liga]

@@darknessblades in my opinion, changing out a board is worth for a "workhorse" machine... That one/two machines that you want to give gcode to and walk away knowing the print it's going to be perfect. It's expensive, but worth the reliability in my opinion.

[@HalfwayAerial]

Hey I just wanted to let you know I bought a prusa mk2s that was abused and came with no motherboard and almost all of the printed parts broken. I followed your guide here and put a duet board in it and revived the dead printer and I am shocked at how well it prints. Thank you for posting this guide. It saved me a lot of time getting it running and is now my best printer.

[@JandCanO]

I'm never going back to trying Marlin after making some printers with Duet boards. It's so much easier to make changes on the fly.

[@pizzablender]

I'm using Klipper for the same reason.

[@forerunnert]

I'm running both and they're fantastic

[@TuxieBSOD]

I find that no probe apart from inductive probes work reliably on duet boards. Bltouch support in particular is ratshit and inconsistent, randomly triggering and not. The boards are also incredibly expensive. Not worth it.

[@alejandroperez5368]

@@TuxieBSOD Original Bltouch?

[@TuxieBSOD]

@@alejandroperez5368 Two generations of original bltouch and one 3d touch was tested. Seems like the firmware does not actually check for status changes at all, and just rips on with it regardless of if the probe triggering status changes. It doesn't reset properly after a reset either, had to pull the power from both usb and external for some really shitty reason. I have no clue why and at the end I just gave up. The firmware is *interesting*, but not *good*. Oh, and of course, the damn thing uses connectors *all* motherboards don't use, so starting to use the board is a crimping bonanza and switching back from it as well. The whole thing reeks of newly graduated students. An interesting mix in terms of hardware, some interesting thoughts when it comes to firmware, but no consistency and not following any industry standards even when it comes to really basic things.

[@Redemptioner1]

Please do a video on the PWM frequency issue you had with the Hotend

[@ldltutorials]

I'm also doing a project with a duet board and I'm really impressed by the quality and the simplicity. Happy to see a video about 💪

[@oljobo]

Great video! Thanks! 👍😊 You forgot to mention though that ANY old phone or tablet (that you already have in a drawer) becomes the perfect touch display for the Duet.

[@Macrochine]

I used a Duet 2 Wifi for my Voron 2.4, genius combination. Was also overwhelmed by all the settings at first but now I think that this system is just the best there is and am really happy with it. The automatic bed leveling with the 4 Z motors of the Voron 2.4 is just soo satisfying :) I'm using either my PC or a cheap Fire HD 8 for interfacing the printer and I don't miss the actual buttons :)

[@EducatingSavvas]

The Duet is very impressive - I use it for CNC router control. It's also a great entry into understanding gcode and these tools work.

[@marko2210]

IMO RRF kicks asses to all of the alternatives combined. Price/performance, ease of use, superb support, connectivity and relibility, just bizzare control of your build.. there is no match. Whoever says differently, just hasn’t used RRF (on Duet) yet. I usually have screen temporarily connected as a gadget for machines i tweak and mod (Exclusively IDEX and Quad..), otherwise, when doing remote printing or just ordinary use, the screen is not used or needed by me at all. As Stefan mentioned, it is intimidating at first, but the learning curve is very, very steep and great documentation helps with that fact. And since alternative boards got supported, i think this is the beginning of a great transition towards RRF in general. I am running a group, dedicated to RRF driven multihead machines that stemmed from upgrading my Tenlog D3 IDEX. I help people upgrade their machines and tutor (when needed) total noobs in this process. And while some never even heard of RRF or Duet, they all manage to do it. Not a single disappointed user for now. That tells a lot of RRF. You can check out what RRF can do or ask more at my fb “MarX group” (search FB groups or just follow the link) facebook.com/groups/237163797566846/

[@MarinusMakesStuff]

I can really advice people to check out the RRF port indeed. I got it working on an SKR 1.4T with an ESP8266 for wireless connectivity. It's cheap and works great.

[@dreamcat4]

Stephan, you ask which control board we prefer. And say you will be tring next some flybpard duet clone. The thing is that while flyboaards give more memory / storage space for installing RRF... Actually the better quality of chinese brand is fysetc now these days. Their brand new fysetc spider with x8 drivers 2209 is based heavily on the proven s6. This is a product designed specifically for klipper. it has been thoroughly tested before release and is best new board available for this purpose (as of april 2021)

[@christophmuller3511]

You are talking about a board which has not yet shipped and hasn’t been tested widely yet for potential bugs in multiple installations. It will likely be a good board, but don’t label it as the best one yet until it is actually sold.

[@dreamcat4]

@@christophmuller3511 normally i would agree with you. and very much so in the light of questionable new boards being released by companies such as BTT. however in this particular instance the manufacturer has been very conservative with the changes (from previous s6 model), and i also have seen enough behind the scenes to trust the level of pre-release testing here. specifically being in fact a lot more than anybody else's typical level. aside from perhaps duet too. yes it's not possible to rule out the possibility of unknown bug or other = yes. and i acknowledge that point. however even with also accounting for that occurring it's still overall the best board out there IMHO by a wide enough margin. and i say that also including the higher level of after sales support and care is higher than any of the competitors (which most directly are the flyboard or the BTT GTR, but more generally all the other options also). again all aspects types of support being considered, including things like the way they do their documentation, provide klipper profiles etc.. this is with also considering what people recognize positively as duet level of quality. (although depending by other's views / comments duet's own after sales support may vary by experience).... TLDR i'm not actually here to tell anybody they must buy this product instead over something else. but mostly to be at least be aware that it exists. and be aware of it's true quality etc. being higher than you might initially believe. rather than mistake it for something else of a lesser quality such as offerings from other chinese brand. just to give it a fair and reasonable examination and not end up regret missing this option in ignorance of it, over something else that is in fact inferior in one way or another. so i say again: while your general point is acknowledged, it's just not really something that stands up to the higher level scrutiny which i have applied in this case, and you really don't have to trust me on that! pretty confident that time will tell, for being that the assessment here it's not going to change significantly or in any meaningful way

[@certified-forklifter]

Duet/RRF is really cool but also expensive. Regarding the screen, yes I really miss it. I'll probably need to get one. Please more DIY/modding videos! They are awesome! Thanks and have a good one

[@FrancoisMathieu]

I have used Marlin, but I finally settled on Klipper.

[@GaryD9]

Welcome to the land of Duet-based printers. The LCD question is a frequently asked one. I tend to favor having a physical control panel at each of my printers. This allows me to continue controlling my printer when my network goes down, I've left my phone in another room, etc. As well, it's nice being able to glance at the printer and see the current status of things (such as estimated time remaining, temperatures, etc) without needing to use another device. I really can't comment on having a preference between Marlin or RRF. I did have a Marlin based printer once for about 2 weeks before swapping it for a flashforge creator pro. As you may know, the FFCP doesn't actually use "gcode" commands, but instead uses pre-parsed "x3g" instructions. Ever since converting that printer to a Duet Ethernet about 4 years ago, I haven't even considered a non-Duet based printer.

[@theheadone]

Stefan, welcome to the wonderful world of Duet! Once I got my railcore, I converted all my other printers to Duet (other than my MK3 since it just works so well) Honestly, the screens aren't great, especially for the price, the touch sensitivity is bad. I'll press a button and something else gets pressed probably 10% of the time. Still, it is nice having a screen, fysetc makes a knockoff version that still isn't too cheap, but it'll save you some money. Mellow makes one as well, but I didn't like the interface on that one since it uses their interface rather than the normal duet one.

[@mindbendernine]

Good luck with Support if you ever need it. You're basically at the whim of a Support Forum and anyone who decides to help (or doesn't). This was one of the worst experiences I've had to deal with - gave my Duet board away.

Nice. Would love to hear more about Klipper and the Voron project on the next video.

[@vikypond3183]

I am not surprised the prusa board gets damaged. The box of board enshures overhead. Elektroniks need proper cooling, or they die early. Print a bigger Box for your new board, place a fan into it (big slow -> silent), add distance to the heatbed. Put Heat sinks on the Mikrokontroller and on stepper driverst. Otherwise the replacement board gets killed too. And put heatsinks to all stepper motors. Especially the extruder ;-) This really increased quality of prints on prusas.

[@Dramaican88]

Duet 2 Wifi and 5 inch panel due is what I use fro my main own custom printer for almost 3 years now. The user interface is more a matter of habit. I got used to preparing print jobs at my PC and the web interface, but use the touchscreen for macros (preheating, change z probe offset depending on the side of the flex plate I use etc). RepRapFirmware is very good and by the time I have my Voron 2.4 build RRF 3.4 with input shaping might be released. So great to see that there is active development and it might also be a good follow up video for you, to test input shaping on the MK2 and maybe later get a Bear upgrade 2.1 frame for it and test input shaping with a better frame.

[@Michael_G980]

I've been using RRF on my btt skr 1.4 turbo board with the wifi addon board and loving it. Will probably move my Corexy hypercube based printer to rrf as well if the firmware port supports the btt gtr pro v1. I love the web interface for duet, so much easier to use the printer than marlin.

[@nortonp240]

anything that can run Klipper is my board of choice

[@christophmuller3511]

Just get the fysetc Mini 12864 for around 15€ delivered from AliExpress - plugs into the board directly and allows for all the necessary controls on the printer.

Better get an SKR board, Lot of people putting in SKR1.4 Turbo's in their prusa's because it has a TON of features. They also released an SKR2.0 recently it has RepRap support + wifi webinterface too. and you can still use your old screen... Even fot the SKR1.3 and 1.4 you can get a WIFI module. Duet's are just overpriced but cool and great CNC boards. but not so much for printers. If 1 stepper driver burns. you can throw away the complete board. with the SKR's well... you can easily replace them.

I'll see how that goes when the machines are ready haha

My main printer is Marlin, but I had a second that was Klipper, I'm planning to rebuild it soon with an extrusion frame as it used to use an acrylic Anet A8 Frame 😅 Klipper had some really good movement capabilities, and I got very good printing quality using the old RAMPs + Mega combo!

[@fvrank]

Hi Stefan, thanks for all great content you create. This video convinced me to go for Duet in stead of replacement of my current Lerdge X board. I replaced all steppers with TMC2209 but it's not working great. The lerdge is having trouble with Z and E and is not reliable even after tuning the Vref so a replacement for this is the next step. I get it tomorrow.

[@vhoward1122]

I experimented with a Lerdge board when they first showed up in the market. Had nothing but problems with it and ended up bricking it trying to update the firmware. Then I discovered the duet2wifi that had just been released and I was pleased with it. I converted all my other printers to it and have no regrets.

[@fvrank]

@@vhoward1122 i like the easy user interface of the lerdge board. But with ease of use comes restrictions as using octoprint for remote file upload. After setting up your printer on a Duet it is as simple as the lerdge. Working reliable with quiet drivers was my main reason to switch.

[@flyguy8791]

I'm researching the Duet board as a replacement / upgrade from some proprietary 3d printers I was given; I think it will work well!

[@AttilaSVK]

I tried RRF on my SKR v1.3 with an ESP32 plugged into EXT1 and EXT2 connectors for WiFi connectivity, on an Alfawise U20 modded to have a Prusa i3 MK3 X and Z axis and X carriage. I never got sensorless homing to work reliably, I couldn’t figure out how to adjust the Z midpoint for the bed level map, so it was always in the blue to green region. I flashed back Marlin after two weeks and I’m happy. On the other hand, I ran an MKS Gen L board with TMC2208 drivers in standalone mode on a Prusa MK2 clone. There is a port of Prusa firmware 3.9.0 to RAMPS and compatible boards (like the mentioned MKS Gen L), so I was up and running in a few hours. It was even more quiet than my MK3S :D

[@trixigt]

IF you hade an old android phone or tablet you could use it as a screen, the duet web interface has room for a webcam and if you download a webcam app for the android device you can feed that into the web interface making it a multi use device. Just attach the device so that the camera sees the build plate and you have a way to see your print from remote. I use a old 7” tablet and it works great! Keep up the good work with your great videos!

[@Exstaz]

Duet 3 mini also support display mini 12864. Just so you have some control by the printer if needed. Duet will also get inputshapper in 3.4 which is very close.

[@anthonyrich1592]

Be aware that you'll need to use a 3.3V compatible 12864 controller, such as the FYSETC Mini-12864 (and possibly the BTT Mini-12864?), otherwise you'll need a 5V-3.3V level converter as discussed in the Duet user forums.

[@SirRado]

I wonder if this board would be compatible with an old monoprice select mini v2... 🤔 It's been a surprisingly good little printer, and this could be a great excuse to move the electronics outside of an enclosure while also upgrading it.

[@billcampbell6857]

I have just replaced the Rambo on one MK2.5S after 3 years of use. You have given me a great alternative if this one goes down again.

So tempting - my first 3D printer was a QU-BD Two Up kit that had _all_ the problems, including (surprising) melted bed heater connector. A modern controller would do a long way to make it better.

[@jaistanley]

I've been using a duet board on my machines for a few years. Bought the large touchscreen because I thought it would be useful and look great. I can ho early say I've barely EVER used it. It's handy to be able to look at the machine for the status, but not that handy.

[@DenKonZenith]

Got an old MK2 kicking around. Hasn't had any issues yet, but I've got options if I blow it up or feel like ripping it apart, neat.

[@ChannelJanis]

I have a Duet Wifi board with Duet touch screen. I use the screen for stopping printer quickly when print fails (mostly because of bed adhesion), swap filament (heat up nozzle, extrude old color). Also really handy to select a print. When I use iPad to control Duet, and iPad goes to sleep, I have to reenter password. When fiddling around printer it gets to sleep too fast. Currently my printer is in a location where I can not see the screen, only the stop button, and I really miss the screen. Will have to relocate it, need longer cables to move it to front.

[@SinaShahsana]

I don't know if you noticed or not but caribou only defines PIND v2 in their config, they don't really make use of it for probing compensation, I studied their whole algorithm. I couldn't find any sign of any G31 line that changes trigger height for temperature. their firmware works because they make you do first layer calibration for different material with macros. lol

Waiting for my MK3S+ to arrive. Now I know what to do if it ever lets the magic smoke out!

[@MMuraseofSandvich]

I didn't notice the MK52 bed you added until like the last few minutes of the video. Nice! So essentially a MK3(s?) with the old frame and no screen and probably better controller/firmware. I haven't decided whether a screen is a necessity in my workflow, but I do prefer it over accessing the printer from my phone. I like the fact that I can glance at the screen and know the status of the printer without firing up an app or web browser. I know resistive touchscreens are a huge pain to use, and capacitive touch is cool but prone to user error (my fat fingers) and costs more, so I prefer a simple LCD with a tactile interface like an encoder wheel. Web interface is nice, but it's another thing to secure on my network, and there's a lot of damage a hacker can do with access to heating elements. Granted, that risk is not very large compared to being a large datacenter with lots of patented information. The other reason I prefer an LCD is because we have enough companies releasing headless devices that are useless without a buggy app.

For those that want to get the same crimping tool as "CNC kitchen" beware that this tool is a bit difficult to use. and you might burn trough a lot of connectors before you get a good crimp. But once you get the hang of it it will give good crimps for simple connectors that do not see a lot of stress

[@frollard]

Very cool. I want to upgrade the rambo in my makergear m2 as I've damaged some traces on the unavailable screen.

[@Naqaj]

I've used my maestro for 3 years now without a screen, as it just wasn't neccessary. The one thing I did though was to add a custom start and end G-Code that reconfigures one of the end stop switches into an emergency stop trigger. Just in case, you know.

Hi Stefan, your probe is not activated for temperature compensation. I found out the hard way there is about 1mm of difference when the probe is +50 degrees so the factor should be 0.02 in the G31 command. If you have firmware < 3.3 you should use a C before otherwise a T. My lines are now: M308 S2 P"temp2" A"Pinda" Y"thermistor" T100000 B3950 ; temperature of PINDA2 G31 P500 X0 Y-24 Z0.95 S21 H2 T0.02 ; T' (temperature coefficient of Z parameter in mm/°C, default zero in your case if you would like to make it working: G31 P1000 X23 Y5 Z1.4 S21 H2 T0.02

I find the Marlin firmware vs RepRap Firmware in context of RepRap project very confusing. RepRap project is any firmware but embraces Marlin and RepRap? What is history of two? Who came first, who are the different development groups?

[@heyallenify]

I'm personally running a couple Duet Wifi boards, and getting ready to build my first CoreXY printer (a TwoTrees Sapphire Plus), with a Duet Wifi already sitting here to install in it. I'd barely touched Marlin on an earlier MKS board in the delta printer kit I bought, before getting annoyed with it and rebuilding it with the first Duet I bought, and have since used them on all my printers other than the little Monoprice Select Mini (I've even considered it getting swapped, but a ~$130 board in a printer that I bought for $100 is pushing the convenience issue a bit...)

[@hayden9944]

Did you not use input shaping? Its really easy to configure and will improve ur prints and allow you to speed them up.

[@fataxe1]

Buy a cheap tablet off amazon and use that as the touch screen. I think there are some el cheapo ones on Amazon that would work mint. The duet firmware really is intense how good it is. No stupid sd cards, no stupid lag, no stupid buffering. Just money. You also know for a fact if your commands work because it's built in debugging will tell you if your commands are junk, unlike marlin which will gladly kill itself

Would a touch screen intended for a pi 3 work?

[@fataxe1]

@@abhimaanmayadam5713 probably not hooked up directly. The touch screen is basically a small computer that runs the interface on it. It's only a three wire connection.

[@theclueless11212]

I also burned through all my bed heating power terminals; simply soldering the wires instead of using Prusa’s connectors has been holding up for a few hundred hours at least

[@yonutz333]

Could you please detail a little bit more how you used the Marlin generator to tune the pressure advance in Reprap? I remeber I had issues setting it up and gave up ☹️...

Nice. Going to get one of these boards for my Ender 5 Plus after I convert it to CoreXY

[@PatrikTheDev]

I bought a PanelDue clone from China and it works very well (I would love to buy the original but it’s too expensive for me) I hated the look of the UI so I implemented a nicer dark mode (now part of the official firmware)

how does this compare to a klipper conversion?

[@milomirate447]

What about crash detection, power panic, live adjustment of the Z babysteps, arcs, sanity-checks of the nozzle diameter and firmware version, etc?

[@CNCKitchen]

Crash detection: check Power Panic: possible, though might require an additional capacitor on the input rail with the existing PSU Babysteps: check Arcs (G2/G3): nothing easier than that Sanity check: probably not in the Prusa-way

[@markuskus5694]

Lerdge Boards are also very easy to use

[@MichaelJHathaway]

@CNCKitchen - I printed your Duet 3 mini box, very nice by the way, but it is only set up for a wifi card and not the ethernet model, so modifications had to be made. *Would it be possible to post your step files for that?* I followed your guide the best that I could but you had left out io settings and I had to back trace them by looking at our config file.

[@peteradshead2383]

You connect via pronterface , and set up your router's password and ssid and find out it will not connect to your router because pronterface converts your password to all uppercase and you spend the next 2 hours trying to workout what's happening !!!

[@stevenmcculloch5727]

Duet recommends using the program YAT for sending gcode for initial setup

[@CNCKitchen]

Very good to know. Worked for me, though.

[@andreask87]

You could also just eject the sd-card and change the config files with the passwords on any pc that has a cardreader ;D. However i kind of know your pain: After a change of my cable-internet-gateway my duet2wifi wouldn't connect to my network anymore, even though ssid and other wlan-settings were the same. It took me some time to figure out that the cheap-o wlan on my new router as well as the duet were simply incompatible with each other :( . I had to get around the problem by buying an additional wlan-access-point that my duet would connect to.

[@peteradshead2383]

@@andreask87 My way around it when I worked out what was happening was change my password to the uppercase version , and make a macro : M552 S0 M588 S"*" M587 S"mysidd" P"mypassword" M552 S1

[@billereses4935]

I am pretty sure, Stefan uses the very popular FRITZ!Box (in Germany) where the default password has only numbers, so the issue didn't occur for him ;-)

Your config file does not include PINDA probe temp compensation. Would love to see your tune setup.

[@lucamatteoluppi1117]

hi stefan, after some time, why don't you propose a new video with klipper conversion of the mk 2.5 with duet 3 mini 5?

[@AndrewAHayes]

I have a clone duet 2 on my Pro 3G V-King but am considering getting this one and using the clone board for a CNC milling machine project.

[@Kmnri]

I don't miss physical screen at all with klipper, phone is way more ergonomic, has better touchscreen and I dont need to bend each time i wanna change settings or operate printer.

[@Silidor372]

I would totally buy the broken Rambo board :D.

[@bj97301]

Very good points. Thank you.

[@mikeschubert4890]

I use Bigtreetech MKS Boards with RepRap Firmware - works pretty well too....

[@rpavlik1]

For those JST style connectors, there is an iwiss crimping tool that works much nicer than the ratcheting ones. (Big Clive did a video reviewing these tools) It only crimps a single point at a time, so you use it twice for those connectors, but it's much easier and more precise. I've found the original ratchet tool is still better for the Dupont style connectors.

[@AndrewGillard]

It's not quite as simple as "ratcheting tools are bad", unfortunately. There is a wide range of crimping tools, each designed for different connectors. Whether they have the ratcheting mechanism is largely unrelated. (In fact, the ratcheting mechanism can help ensure you apply enough force to get a good crimp - though you have to turn up the force dial quite a lot in my experience...) I have an iwiss SN-01BM ratcheting crimp tool that works very well for JST-SM and Molex KK-254 connectors (clones of the latter are often called "KF2510" - it's the connector style that Big Clive has long favoured, and I use the same clones, sold by Rapid Electronics, that he does). It also works decently for "DuPont" connectors. I think it will do JST-XH and maybe JST-PH as well, but I dislike both of those (very high retention force combined with a tiny connector housing that's impossible to grip 😒) so I use KK-254-style wherever possible. That SN-01BM tool was supplied with a set of JST-SM crimps from Amazon, and in this case I was lucky that _the kit contained the correct tool for the accompanying connectors_. You'd think that would be standard, but sadly it's not. I bought a kit of "DuPont"-style connectors that was supplied with a ratcheting crimp tool that _looked_ very similar to my SN-01BM, but it produced _terrible_ crimps in comparison; it was utterly unsuitable for the connectors it was shipped with 🙄 (I can't seem to find that tool right now, or I'd give its model number... It wasn't badly-made, it was just the wrong tool.) That mismatch of crimp tool to connectors is very common from what I've seen, and a lot of Amazon/AliExpress product listings for crimp tools don't correctly list the connectors the tool should be used with 😕 It's worth seeking a list of tool-vs-connector suitability, although I think it's really the die attached to the jaws of the tool that determines the compatibility, rather than the main tool itself...
