I like your longer format videos, but understand that shorts are the only things that get views anymore. Glad you're still doing them.

[@MihaiDesigns]

Glad you like them! I want to do more.

[@Zellonous]

Everything has been gradually moving towards more and more instant gratification. There is a time and place for both formats.

[@Marorrai]

Agree 100%

[@btran3224]

I really enjoy this video format. It shows how 3D printing is not always just print and go. You have to constantly troubleshoot and adapt to make your printer work.

[@MihaiDesigns]

Very true!

[@DEtchells]

Unless you have a BambuLab X1C - but that’s a totally different price point :-)

[@TBL_stevennelson]

I really Like These Printers It was my first Direct Drive Printer and it blew me away at How easy it was to use and Adjust

Yay! Thank you!

I bought the KP3S Pro about 2 months ago and have been running it 24/7. Great value for the money. I immediately ditched the spool holder and bowden tube in favor of just hanging filament from a lamp above my printer area. I also immediately added a textured pei sheet in lieu of the glass bed. Filament needs to be straightened and cut to a point to feed it into the extruder. Also as you noticed the z-end stop screw is too long, especially once the glass bed is ditched so file it a bit shorter and you're good to go. After over 1200 print hours at this point the only failures I've had were from when I forget to clean the pei sheet every few days/week. If you can't afford a Prusa or Bambu or just want a fun little cantilever printer to try, this is a great little printer for $180ish dollars. They just released a KP3S Pro V2 with Klipper installed from the factory as well for about $280. I wish that had been out before I bought this one since I've been tempted to Klipperize my KP3s Pro since it arrived. Thanks for reviewing this. I'm bummed more people don't know about Kingroon, they're great little budget printers and I want them to succeed and get more people into the hobby.

[@MihaiDesigns]

Thanks for sharing! You really used them and sounds like they're holding. I just got the flex plate as well and looking to try the Klipper one as well.

[@krysgranowski]

Completely agree with you. These compact little printers are so underrated !

[@peleg_ivanir]

It's so fun to see new video❤

[@Reprinted]

I don't mind this printer it seems like the one you would use just for small prototypes and this one seems better than the other cheap ones. I can't afford it now but I might buy it later.

[@jasontrauer]

I had this problem with the z stop screw as well. I had removed that screw and filed it down so that it had more play. Quite the oversight for such a nice little printer. The temp adjustment (no presets) is lame, and no z-offset setting is also annoying, but otherwise it prints well. The KP3S Pro V2 is out now and uses Klipper with a nicer hotend and top-loading of the filament. Love your videos!

[@husandeep637]

Thanks Mihai...Thank you very much...I'm gonna straight ahead buy this soon...Stay Awesome...Ur the best

[@MihaiDesigns]

Have fun with it!

[@husandeep637]

@@MihaiDesigns Right now I have 3D Printers in my school where are good enough I guess...I am printing a lot many things with it..There are some minor issues but I can fix it easily I have liked fixed it 100+ times...But still it prints well...I checked for the printer but I live in India it it not deliverable there...so I have to check out 3rd party webs

[@janpetersen8441]

Finally, a real video. I was thiiiiis close to unsubscribing, thinking you had been lost to the Bamboo AMS abyss of endless tchotchke printing.

[@bricknplay]

I love your videos! I considered buying one, but then got the Sovol SV06

[@vizionthing]

Not bad for the price at all, expect to tinker to tune, impressed with the linear rails

[@Impuritan1]

I put Klipper on my KP3S Pro S1 and makes that great little printer so much better. Love that little thing. Yes, get the all-metal heat brake and for the love of god make sure to put some thermal paste on it. I didn't at first and it kept clogging until I did. It has printed without a single clog since.

[@MrBlakBunny]

i got a non-pro version, i use it all the time with a 0.6mm nozzle for quick prints! its been solid, might be good to upgrade to the pro

[@TAPSSebas]

love your vids

[@tenchuu007]

I like how every tool or comparison part came off the Bambu. 😂

[@Not-Einstein-61]

Thank you Mihai, for your great videos and shorts. I havent seen any video about conecting the KP3S to the PC thru the USB conector. Can it be done, if not, what is the purpose of the USB conector in the printer ?

[@balazslennek]

That's so cool, companies send you so many printers for review, you need to choose which one you want to try 😂

[@alex59292]

He's got a big audience that's why

[@fdavpach]

When you get this printer with the PEI option, the PEI sheet comes on a separate envelope that they ship by itself

[@GeekDetour]

Mihai, I have a similar pile or boxes 🤣 I might take the Crux 1 that looks A LOT like this one you just unboxed. PS: I would tight the springs even more and move the Z-Homing screw down a little more to compensate.

[@quentinroa2573]

I've been using a CRUX 1 at work, I would not suggest getting one. It is a stringing disaster, and they suggest 8mm of retraction for a direct drive. I have an Ender 2 pro sitting next to it though and that is an incredible machine.

[@chuck2501]

I have a KP3s, i love it! I'm using it with a reverse bowden tube + filament dryer that was £29 and doubles as the spool holder :) This looks a little neater but the runout sensor is poor.

[@Zellonous]

To get the screw out, file or dremel a slot into the part sticking out and use a flat head to loosen it. Or maybe grab it with a pair of wire cutters and see if you can loosen it.

[@v1jilante]

I put together one of these the other day, looks like you might have missed the T-nuts and screws at the base of the Z profile (right behind the leadscrew coupler!), having said that, it looked to be printing OK quality wise anyway :)

Just a heads up, relating to PETG/PLA filament swapping: these plastics don't mix well, so you should clean the hotend with ABS between swaps. I got this advice from my local filament manufacturer. They supply a small piece of ABS with PETG purchases. I believe they know best!

[@theglowcloud2215]

Why ABS instead of nylon (cleaning filament)?

@@theglowcloud2215 I meant purge clean, not cold pulling. PETG and PLA aren't mixable, but both mix with ABS.

[@whatisyouremailid]

Your printer is missing the blue silicone sock. Also the leak is not from the gap in heater block and nozzle it's the poor quality of PETG bubbling and sticking to the nozzle itself. If it's a leak it should happen on PLA as well.

[@matroosoft4589]

Are you planning to review the Sovol SV06? It's the same price but seems to be much better then this one! Comes default with PEI sheet, auto bed leveling, high quality injection molded parts and just a better quality overall. I bought one last week and the first print was perfect right away. Anyway enjoyed this video, keep up the good work!

[@MihaiDesigns]

I don't have one and got a ton of printers already. If Sovol sends me one I can try it out.

[@whatisyouremailid]

Also before you push the filament into the filament sensor straighten about 70 mm of the filament...the holes are too straight aligned as they should be. The curvature of the filament from winding does not let it go straight.

[@BigNoobRoblox]

I currently have a tronxy crux 1 PEI sheet. Pretty similar

[@christianlautenschlager9693]

mannnnnnnn i would love to do this too as a job ❤️

I’m in Norway and I tried addnorth filament but it was bad on both spools I tried so just wanted to mention it

[@HerzogJoni]

I would really like to test a 3D printer like this. If everything works, it's no fun xD

[@Marctron]

I ended up cutting my screw off to get it low enough. It’s even worse with the PEI because it is thinner and you need to drop the Z even more. I let them know via email and a week or so later I had a second screw show up in the mail from them. Overall I love this little thing and it has been a great printer to have at home since I brought the mk3 to the shop for work things.

[@MihaiDesigns]

Good point! I might have to adjust my 3D printed adapter when I switch to the PEI sheet.

[@Wingnut353]

You do NOT need gluestick on that type of bed I have the KP5M and it has the same bed and I had the same leveling issues as you... but the bed is quite nice you just get it hot and it sticks and when it cools it releases just like PEI. I think its PEI glass or something.... if anything you just clean this bed with alcohol and it works good and sticks strongly with PLA in my experience. Also in my experience these printers don't have accurage print head temp but maybe that is just mine....

[@yurek3936]

Upgrade mine with Pei, Klipper and abl. Tossed the z screw away and get ez life. Also the spring hold the z motor and z rod is too high. If you use pei, lower it before homing.

[@marc_frank]

can't see any ringing thats pretty awesome

[@damiansladek]

Can I ask you where are you from?

[@greenman360]

Z offset, the enemy of every beginner 3D printing enthusiast. You can level all day, but you gotta get that offset right.

confusing struggle to assemble a 3D printer😅 Maybe even more confusing than building a big printer like the tool changer😂

33:05....shut the printer down before using metal brush or you may short the thermistor 😮

Best advice ever! Just killed the toolhead on my Snapmaker A350 doing just that. Oh well, it's just money 😢

Linear rails on all axis and even two on Y, but no hard mounted bed and no automatic bed leveling. Swing and a miss.

[@krysgranowski]

Hard mounted bed - what the heck is that? and no automatic bed levelling - why on earth would it possibly need that?

the ultra bases on my printers dont look that bad after years of use, than yours after a few days. And I really dont know, why you used scrapers all the time. Let the bed cool down, the print should just fall off.
