He3D K200 single head delta DIY 3d printer kit autolevel with heat bed- support multi material filament

This kit is undoubtably the worst I have ever built. Parts are threaded where the shouldn't be and vice versa. The instruction sheet is just a bunch of pics and mostly don't show detailed assembly. I have built about 5 3d printers and this was the worst.I would have gotten my money back but my return time ran out with amazon. Don't buy it . it's just a frustration nightmare. I have a full degree in mechanical engineering but it didn't help with this kit.

Thoughts:The printer is pretty good. I takes anywhere from 6 to 8 hour to build. I'd recommend following the picture manual with some references from the video build tutorial. The kit comes with a picture manual and a schematic with the connections for electrical components, these can also be found on the printer wiki. The printer runs on repetier firmware and comes with auto leveling. The z-probe is a simple pressure sensor that fits over the nozzle, so it will need to be removed after you finish running auto-level. Overall it is a good printer, just keep in mind that how well you construct the printer can significantly affect how it prints.Building Notes:Note on the top pulleys on the printer when building (part D1) use the nuts that come with the kit to fasten the pulley, neither the manual nor video show this step.My Issues:One thing that sucked was that the hot end in the kit isn't too great, I had very frequent jamming at the nozzle. So a modification I made was to place a small length of PTFE tube into the hot end just before the nozzle. You can use the PTFE tube for feeding the filament, but will need some sanding on the outside of the tube to fit.

I am very pleased with this printer. This is my second 3d printer. I wanted a mini kossel printer to add to my Prusa clone. The build took me about 3 hours. I located and installed the most recent firmware. The software bed leveling is nice. With the bed leveled I printed a filament blower fan part and then installed a fan for the hot filament. With the cooling fan installed the prints became very good. I am still fine tuning it. I am very satisfied and I would recommend it to anyone who has the aptitude to assemble their own 3d printer from a kit. And as a bonus, this printer is framed with 20/20 aluminum extrusion paving the way for build area expansion.

I have experience with 3D printers, so I was able to overcome the obstacles that this kit provided. My main issue is with the hot-end. Put simply, it doesn't work well at all. Jamming is a very common occurrence with the stock hot-end. Yes, I assembled it correctly with the bowden tube fully against the heat-break. I replaced the hot-end with an E3D-V6 which required printing a new mount/effector because the supplied hot-end is a different shape. Once this was done, it worked much better. But I did a little more.The Repetier firmware that this comes with is... not the greatest. It generally works, but all of the square-root calculations (a requirement of a delta printer) it's asking of the board is a lot, and makes for very jittery printing. I was going to put Marlin on it, but it requires the same sort of processing power. That's when I discovered Klipper. Klipper does require a Raspberry Pi which does all the heavy calculations, then sends the basic movement commands to the printer over USB. The printer runs buttery smooth now. Klipper was very easy to install and configure.I like this printer now with these changes.

Assembly was a breeze to say the least...... I received this printer from my parents for Christmas on Christmas Day had it fully assembled in a few hours powered it up everything was good... however after auto homing it has fully locked up and now nothing moves under power imo this printer is junk and there’s no active support I would rethink the purchase

Brought it and it doesn't work. Tried 5o get refund but company won't contact me back. It's a scam!

This product has not worked correctly since i received it. Verry unhappy with it.

First the unboxing, it was completely covered in metal shavings from the extrusions being cut. Missing parts, very cheaply made. The power supply is extremely dangerous….seriously two prong plug no ground. The instructions are horrible. I ha e had this for a year and still have not been able to get it to do the basic setup procedures. Definitely not for beginners. I have 21 printers and they all work perfectly with some minor tweaks which is expected. But this machine in my opinion is a con. Really really horrible. They need much better instructions and at least have the programming done for you. I wish I could say something good about it but there is not one thing on this printer that is good. Yes it’s big it’s cheap but that’s it. You WILL regret buying this machine
