[@parrottm76262]

Wow, great video on a great upgrade. This type of board is exactly what I want to see in the upgrade space. Further videos on how to really take advantage of this beast would be fantastic.

[@mattchristine675]

I just installed a lerdge z in my ender 5 plus,I couldn't get a k board then,and im still working the kinks out,your video helped alot. I missed the part about filament sensor wires being backwards last night and got a puff of smoke when the wire got hot,I unplugged it quick and it seems to still be ok after swapping pins and plugging back in. I also was stumped over the two wire limit switch plugs and the three wire sockets on the board,till I saw you plug them in, just on the right two pins,I would have never thought of that!!I got the bl touch to turn on and probe twice when the system powers on the first time with no issue,so I think it's right. I'm waiting on a new belt for my y axis before I can test it further. I used the massive Mosfet they included as well.. I have never done anything this involved and your video helped immensely,!! I saw below you put a obligatory post stating the motors might run hot??? And the vrefs might need to be adjusted? Do I need to do this with tmc2209's on a lerdge z board??

[@papyro6830]

This is really cool! I feel like this will become the future. It's crazy how advanced these machines are yet you still have to compile firmware. It's a major roadblock for anyone new to it and I believe it turns alot of people away. This is a major game changer

My pleasure!

[@kerseyfabs]

This is my obligatory post where I will post updates, clarifications, and corrections. Helpful hint: If this video seems too long, check out the "Playback speed" by clicking on the little gear on the bottom right of the video. Enjoy! I totally missed that without UART being enabled by default on the 2208/2208 from Lerdge, the reference voltages are way too high and your motors will run really hot (and loud). This spec sheet has the magic formula which amounts to I = 0.88 * Vref. This means we need to turn them way down from what appears to be the default of 1.25 V which is 1.1 A to 0.68 V for .6 A. If we go by my previous installs: X: 0.65 A = 0.739 V Y: 0.8 A = 0.909 V Z: 0.65 A = 0.739 V E: 0.8 A = 0.909 V If you're not sure how to do this here's a previous video that shows the process: kzbin.info/www/bejne/mXKsYXtqmpuIqck I'll release a separate video on this soon which will also include how to set up UART.

Like the video I have the same board I installed on my ender 5plus but I haven't got it dialed in yet do you have or do you plan on putting out a follow up video from start to finish on the actual setup and settings and leveling that work for you to get it printing well ?

[@enginewatcher6291]

Took the plunge and purchased the Lerdge K upgrade kit, direct from their online store. Have to say very impressed with the quality and the documentation. Today was the day, I had printed every thing ready. This evening I have ran a test xyz cube, with no visible issues at all. Just need a bit of time to test retraction setting and bits. I did do the PID tune that was easy, but would like to see a follow up video. showing the technique to auto level, and set z offset. With the 2 drivers for the zaxis will left to right bed leveling be automatic? 1 thing that has changed the TFT screen is now a version 2 and your case no long fits this model, the jog knob has been moved more central to the PCB, and the fixing holes have different locations. must be pretty new as I have not found and cases that fit this new style yet. Q. is there any way to fine tune the z-offset while printing? or did i miss something in leveling? thanks for your great support

[@Poesghost]

Love your videos! So glad I found your channel. I ordered my Ender 5 Plus from Tiny Machines. Can't wait to get it. What is the case you used for your Raspberry Pi? I have a Raspberry Pi 3b+. Did you print that using PLA or PETG?

Kris, I have just finished installing the Lerdge-Z board in my ender-5 plus, I have the homing working correctly, it goes to the back right, and the BL-touch works fine. When I went to run the first print, the print head came to the center, then went back to the home corner and started extruding. Did you have to change anything in the slicer, from the standard Cura profile for the E5P? Thanks

[@LUNCHBOXFPV]

Hey buddy amazing video! thank you! by chance do you have any info on how to set the z offset with this board..... I cant seem to get it right

[@marcgoodboy1702]

Hey Kris, I am having issues homing the z-axis. The BL touch tests normal, but when I try to home z, the bed does not stop when it comes in contact with the BL touch probe. I've been troubleshooting this for days, and I am getting nowhere. Any advice is appreciated! Thanks!

[@spoton6584]

Just curious after having this board and screen for a couple months now , what are your thoughts on it and out of all the boards you have tested in your Ender 5 plus , whats your go to board ? Thanks for all your hard work making some of the best 3d printer videos on YT.

What was the extrusion rate when printing on the printing screen. I had to put it at 450 is that correct 🤔. Its the only way I can get it to print.

[@tonnictv]

I noticed in your batman bust, the support had some holes in it. I've seen that in the past before-- what is causing this and how do we fix it (if we need?). Is this this related to infill speed?

I just installed the Lerdge K Board and followed your settings for now, but if i set the z offset it won't work properly. It seems like it doesn't use the value that i entered... Any Idea what the Problem is

[@christherk9296]

Love all your videos, super helpful and informative. I ended up buying the lerdge kit, but it came with the LCD V2.1 and it does not fit in the case you shared files of in this video. Would anyone know where I could find the files to print the case out for the V2.1?

[@ShaminMike]

Hot damn I just ordered an ender 5 plus for my first 3D printer and was thinking hey this would be a good upgrade instead of a normal silent board upgrade. Once you started going through the settings though I lost confidence in my ability to understand all of that and get it done properly. Dang it. Looks like a nice upgrade

[@kerseyfabs]

Congrats on the new printer! I'll be releasing a new loadable config file for the Ender 5 Plus soon. I obviously can't support everyone individually on this but I do try to make it easy!

@@kerseyfabs oh you definitely make it easy enough and I was going to give it a go anyway and just take my time getting it right. But they are all sold out at the moment so I might have to look into one of the other options you showcased on the channel. Thanks for the help brother!

[@Karim3ds]

hi, thank you for the great vids, may I ask how long does it take to upgrade the board?! mine is stuck for a long time on a blue screen that says "checking the system UI please wait!" update version 4.3.6.1, thanks in advance

[@kevinbell1138]

Could you have used both, the BL-TOUCH and an END STOP? I ask because the END STOP seams to generally give more repeatable reliable Z-positioning. What I'd like to do is dedicate the SENSOR only for BED LEVELING and the END STOP for homing. I'm using ARDUINO and an MKS G1.4 BOARD now, but don't know how or if it can be coded that way?

[@mururoa7024]

Immediately I love that all the important connectors are clearly labeled directly on the board! BTW, never solder power cables unless they're very low voltage and amps, instead crimp them. Solder tin can break and cause micro-arcs which can cause a fire in the long run.

[@kerseyfabs]

What's your recommendation for connections like this? I thought about using wire nuts or a terminal but neither seemed quite right.

[@mururoa7024]

@@kerseyfabs Here's a good tutorial with 6 different way to do it hobbyhoarder.net/how-to-connect-small-wires/ I prefer crimping pins on them to connect them using push-in wire connectors. However quick splice connectors are the absolute fastest way. If you're still gonna solder them, just make sure a maximum number of strands make contact with each other: they need to be tightly intertwined. The solder should only be there to hold them together, not to conduct electricity, meaning there shouldn't be a thick layer of solder between the two cables (which is what happens when cables are laid next to each other and then "glued" together with solder tin).

[@kerseyfabs]

Thanks Muru! I'll be sure to take a look!

[@CrimFerret]

This was another very well done video. While I think it's cool that there are manufacturers doing different firmware, I'd hesitate to use anything other than Marlin simply because there's so much documentation and help available. If I'm having trouble with something, it's almost certain that somebody out there knows the answer. Not so much with something like this.

[@kerseyfabs]

I completely understand. Hopefully through further adoption though, it will get more usage and more mature.

[@JohannSpringsits]

I enyoid your video and it helps me a lot but on my Creality Ender 5 printer a significant problem arised and i am stuck to solve it When i Home the Hotend bumbes on to the Endstops then I want to make a Testprint and the Hotend bump on the Endstop then again and then it jams on the Endstops and the printer is screaming what is the reason?I forgot to mention I have a Lerdge K board

[@corlissmedia2.0]

What I don't understand is why you set the endstop wiring mode to N-C? Based on the diagram I saw of the Lerdge Board, all three of my physical endstops are Middle Wire / Normal Open, and Botton Wire / Closed? Am I write? I wish you'd reply back on the question because this was a real mess of discussion when I was trying to install the world's most expensive riprap board.

[@enginewatcher6291]

Will this setup fix the 2 most nagging faults with what should be a great printer. I, the dreaded warped bed the BLtouch makes a nice consistent mesh, but Marlin v1.7 (even your compiled firmware) never seems to read it properly. I resort on big prints to use a raft. 2 marlin v1.7 does not read long file names, which is a pain when you want to save great prints with basic design info for my own back catalogue. Great video again must sort myself to get on the patriot list.

[@gizmodavefpv5576]

Thank you for the video. I am considering this modification on my Ender 5 plus and was wondering if the new Lerdge Z board addressed the issue with Octoprint? Too bad they stripped several standard features off the K and called it the Z. Now you have to purchase more add-ons to get the functionality of the older board.

[@kerseyfabs]

From what I've heard, they fixed the OctoPrint issues a while ago. I haven't confirmed this myself but it's what I've been told.

[@nicolaasalbertse3473]

[@adolphweidanz2143]

Great job, I'd like to see if Marlin could be put on it. I'm also interested in hearing more about the octoprint issues. I don't think I'd upgrade to a board that didn't have good communication with octoprint.

[@kerseyfabs]

Thanks! I'm expecting that they can work out the OctoPrint issues. I'll keep everyone informed.

[@td3dp533]

Octo works flawlessly with Lerdge boards, I have been using them fault free for 4 years now. Marlin has been ported for Lerdge but it doesn't function as nicely as Lerdge FW. In my years of using Lerdge boards, I have NEVER once ever said to myself, gee I wish this was marlin. It is significantly better! Beware of one youtubers opinion regarding a feature like this guy with saying octo deosn't work, it does and it does well!

[@maiko6862]

Be interested to see your high speed Octoprint test results with either the Cura Arc Welder plugin or the Octoprint Arc Welder plugin.

[@kerseyfabs]

It's officially on the list!

[@LegalEliminator]

you rekon this would be a simple enough thing to do if you were going straight from default main board to this? seems like for the most part it's plug-and-play other than some configuration stuff and swapping one or two pins. I'd also like the thank you for making this series on the ender 5 plus. seems no-one else out there has made any worthwhile videos on this printer and no one really seems to know about it. when i finally get around to getting mine i've already decided that im going to get an exo-slide kit at the same time thanks to the video you made of them, and your fixes for the BL-touch seems easy enough to do.

[@kerseyfabs]

I think this is a good board upgrade for those not interested in Marlin. I hope to receive a fix on the OctoPrint issue. I'm glad you're enjoying the content. Thanks for watching!

Would you happen to have the pin diagram for the Geeetech Smartto V1.0 motherboard used in the A30T?

Sorry but I don't have one of those. Have you checked the board to see if it's labeled?

Would you recommend this over the normal creality silent board they are a few dollars different? I have to replace since my stock motherboard died.. thank you for your input and sorry about all the messages today 😅

I need help. Follow your video installed the board just fine but the z axis try push up the extruder and the BL touch do not stop it. What do I do wrong? I need to reverse the Z axis motor direction also than the video. When Z+ press on the screen does the bed suppose to go up or down? Because if I follow your video direction the Auto Level probe test about 10 inches above the bed. What is my first step to test the BL touch work correctly?

[@kerseyfabs]

1) It sounds like your black/white BLtouch is not wired correctly. Double check that one. 2) Z+ should bring the bed down because you are increasing the Z height.

[@mrteausaable]

@@kerseyfabs 1) I try flip the black and white wires (Opposite than your video) and now when I go to Auti Leveling Setting Probe Wiring Mode NC it does not beep any longer. 2) The Z+ now move the bed down same as your video, just to confirm. Now when I do the Z axis home, the BL Touch turns to blue (red off) and the probe is down. But when it reaches the BL touch it does NOT stop and the nozzle crash to the bed. I have to do emergency power off. What is the problem why the BL touch does not stop the Z motor? What setting do I need to change, is the probe wiring need to be N-O?

[@mrteausaable]

Thanks KF, got all to works now but I still have one questions on the stock BL Touch and Extruder mounting what is the Off set values and how to measure it correctly? You mention the Z axis need to be -3 but +3 seem to work also?? Why?

[@Dylise]

Bro, your great. I have the regular Ender 5. Can't stand the Cantilever bed. I'm really considering the 5 plus now for the volume, dual z, but mainly because you have an extensive upgrade library of info I can use to make it better. Will you be messing with the Ender 6 in the future?

Thank you so much! I do have an Ender 6 and will be taking a look at it as soon as I can!

Great video love the bord I just have 1 question what sd card extension do you use every extension I use I get a error with printing ( storage device error ) and have tried some extension cable even usb but when I put the same micro sd directly in the bord it works perfectly best prints I ever made .

I included links to all of the parts I used in the description. I've been using this one on multiple boards and multiple installs with zero issues.

[@truestreetdevil666]

@@kerseyfabs well I got the micro extension cable the one you are using still the same error maybe it’s the psu dying still using the original power supply maybe the power drops during print but if I put the sd card directly in the board it works great.

Could you do a video on the UART settings like step calculations, vref, and all the other features of the 2209’s. I’m stuck in legacy mode until I can understand the steps settings in UART. Thanks

[@kerseyfabs]

It's on the short list! Thanks!

[@DXJP]

@@kerseyfabs Thanks. And thank you for all the great content.

[@krymly]

If I understand correctly the unique selling point of this board is that it runs plug and play, due to using its own custom firmware, without having to compile stuff. So obviously I would be interested in hearing more about the features in that, and if they work well (for improving print quality). From the top of my head, how well does linear advance work, does it support dual z leveling, probe grid size. Generally speaking: How does this board+firmware compare feature-wise to stock ender 5 plus, and a custom marlin on a BTT board. And of course I'm interested in uart mode, and what that could do for me, driver-wise.

[@kerseyfabs]

Thanks for the feedback!

PID!!!!! I'm getting this for that feature. Our bed is warping and the PID control of the bed looks to be the solution. However, our current board will NOT allow for changes. (maybe a knock-off). Going to take a chance and order the board. I'm a Mechanical Engineer, not a software geek. Marlin has proven to be an absolute nightmare. Should have done the PID as part of this video.

[@ydeardorff]

where did you get that control box for your electronics?

[@kerseyfabs]

If you're talking about the yellow printed pieces, the links should be in the video description. Let me know if something's missing.

[@NicholasMavrikBrandt]

this sounds cool, but if your going to do this, just go TH3D, USA support and some of the best support you will ever see in the 3d printing market, they went above and beyond for me with fixing issues I had even though it was out of warranty.

[@PaganWizard]

I liked this until you mentioned that other displays are not compatible with it. I have a BTT TFT70 display waiting to be installed, I just need to find a case that I like for it to go into, and my choices are pretty limited for now. I also am very new to 3D printing and have absolutely zero designing skills. I'll just keep patiently waiting for your SKR PRO v1.2 video. I have that board already, but I bought it without drivers because I wasn't sure which drivers were being shipped from Amazon, AND more importantly, BTT's webpage shows six different drivers. I'm not at all sure which ones to get and which ones perform better etc. etc. etc.

Getting the ender 3 v2 with mosquito hotend.... Would you recommend going with this board, Using stock board with a raspi4 with Octaprint, or going with duet 3 board?

[@kerseyfabs]

Right now I can't fully recommend this board if you plan to use OctoPrint. I hope they will have the bugs I found fixed soon. So, if you plan to make a purchase soon, go Duet.

[@bitrage.]

@@kerseyfabs Is it "better" to go with a duet 3 (could be hooked with raspberry pi 4) or is the new ender 3 v2 board with raspberry pi 4 pretty much same?

[@mrteausaable]

I just make a few prints using this board and it print very nicely. Now I noticed that the hot end fan is not coming on when printing. Only the Heat Sink fan on when heating on. Is this normal printing PLA the hot end fan not comes on on this board? For testing I swapped the Hot end fan and Heat Sink fan connectors on the motherboard it is working correctly. How to test this hot end board pin?

[@kerseyfabs]

The cooling fan should definitely be turning on. Make sure you're connected to the right header. You can test the cooling fan by itself on the Control page. There is an icon that looks like a fan that will allow you to set the speed.

[@mrteausaable]

@@kerseyfabs It works now. The board should have manual explaining all this. Do you know why this cooling fan not automatically comes on? What percent should I put on? For PLA is that 50% or 100%.

[@kerseyfabs]

The part cooling never comes on automatically from the firmware. Your slicer (Cura probably) should have a setting that tells it when and how fast it should cut on. Usually 100% for PLA.
