I found the K3PS a couple months ago and man, these things are absolute work horses... Definitely would recommend Octofarm for your setup, if you haven't considered it already. Streamlines all the octoprints into one (Saves me a couple hours a month just with managing printers). Also worth noting with the K3PS : Stepper drivers are removable (Super awesome since it allows for drop-ins of other drivers like the 2130 or 2209) And the K3PS control board has a dedicated BLTouch slot, which definitely has its own market of people (Like me who always wants more from my printers)... I think a accurate representation of these things is I had 2 working printers and needed to make 100 parts (30 minute print per part) in under 36 hours, so I had almost no room for failed prints, and the Kingroon worked flawlessly with no failed prints and parts that were perfect in tolerance...

i bought the K3PS thanks to your page, saw how many you had which meant you REALLY liked them. i am beyond pleased with my purchase. barely any maintenance and it prints good if not better than its competition.

I bought a kp3 a week ago and a day later I bought another one. They do the trick pretty nice. XYZ test cube 20.08 + - .04 on PLA after it cooled. Farming is appealing.

wow it's like my Cetus but open source. perfect! been looking for something like this.

Just brought one, I love it.

Just bought one to replace an old Monoprice Mini, the fact that several people are using these inexpensive printers in print farms speaks volumes.

I've got 2 that I've modded and really like them except for the factory firmware. Both printing with .6nozzle @ 150mm/s with 2000mms/s acceleration and jerk value of 10 and they print quite well. Both have rails on all 3 axis, volcano heat block and nozzle, hotend carriage that accommodates 4020 fan for hotend and better part cooling ducts, pei plate. Once everything finishes get here, I'm putting a 115w chc, cht nozzle and adapter, bmg extruder, mks pi with 3.5" touchscreen for klipper, 60mm nema17 for the y-axis and a 48mm for the x-axis, good belts and tensioners on x&y axis. Right now I'm limited by the y-axis skipping steps @ or above 200mm/s with current accel/jerk values.

is there any more info on the kp5s? their website has the kp5L and kp5M but they look just like an original ender 3 without any of the things you mentioned.

If you are making money with prints like these then definitely more power to you. I'm still trying to find ways to monetize my printer that I invested 500 and countless hours into.

What spool holder is that?

make sure youre using some sort of filtered enclosure when printing plastics such as PC

Link to the write up for octoprint?

Nice video! Did you update the firmware and did you change the drivers?

I just got the kp3s and yes it’s awesome I was just starting a print farm would you donate a machine lmk thanks 🙏

anyone have any issues with the under powered power supply? great video Mike!

So, do you run klipper on any of these. Also, do you ever print ABS with any of these? Supposedly it is able to, but I have not found anyone who has done so.

You cited only a single zscrew on the ender, but the kingroon only has a single z screw.

I don't use octoprint because it bypasses thermal runaway protection.

Sorry, but calling a HDMI connector for this particular application cool is just plain idiotic. You need a locking, vibration-resistant connector with strain relief, NOT HDMI/USB or whatever other popular connector that is misused for this purpose nowadays. There is a reason why cheap manufacturers usually hotglue the shit out of JST XH/PH when used on printers

I’m new to 3D printing and after much research and reviews I choose the KP3S as my first printer and I noticed the above filament holder can I get a copy of that please thanks and your videos are great I’m learning a lot from you thanks 🫶🏼🤙🏼
