Describe your issue:

I am new to Klipper and Mainsail. I have had a Creality K1 Max that I wanted to upgrade to color. I bought the CoPrint solution for Klipper and have been working with them to setup my printer. However, I’m struggling with the lack of documentation on how to setup and test the extruder and print head for managing the filament.

Is there any documentation out there for how to perform the filament cut/swap/extrude out there for multicolor printer control using Klipper?

Hello @netguy72 !

You may ask Creality for that:

https://wiki.coprint3d.com/ seems to offer a quite comprehensive Klipper guide as well.

I was able to finally get printing working but I’m surprised that standard functionality to extrude and retract via klipper or basic gcodes are not supported. I can see that CoPrint is partnering with Creality on adding color to some of the older models as they did a show at CES this year in partnership.

I wonder if it would be easier to support this via Raspberry Pi…

Last question, how do I set the max bounds of my printing plate for the G28/G29 commands? The printer head keeps bumping the door and knocking the magnetically attached guard off of the head. I simply want to reduce the max build plate size so that the home command doesn’t keep bumping into the cage.

Typically, the boundaries of the movement are set via the endstop and min/max positions. See Understanding X and Y Axes Limits and Homing
