Ok, finally got my K1 working again (had to replace the mainboard) and ready to tackle getting the 3dC set up, but I have some questions. 1.Given that the k1 is running Klipper, do I need to install the switch still? I thought I saw that Klipper printers don't need the switch, but all k1 setups i've seen have the switch. 1a. If I DON'T need the switch, how do you trigger the change of filament (Pictures of how to wire would be greatly appreciated) 2. Is there a way to use the included filament sensor with 3dC?
2a. If yes, how?
2b. If no, how does one disable the sensor? 3. Any "gotchas' I should be aware of for this install? 4. Last, I've printed this 'dry box/spool holder' that can hold 4 spools above the printer. Anyone see any reason it wouldn't work with the 3dC? https://www.crealitycloud.com/model-detail/65bc076828a3f0d2cec52005 Thanks all!
You don't need the switch for Klipper. I made a klippy extras module for the 3DChameleon. It's available here: https://github.com/3DCoded/3dchameleon-klipper. The wiki there has wiring details for the 3DChameleon.
The klippy plugin lets you use the filament sensor to detect failed loads and unloads. You can disable the filament sensor if you want. See https://github.com/3DCoded/3dchameleon-klipper/discussions/3#discussioncomment-9038929
I recommend using our setup instructions first before you attempt to do anything that is Klipper specific or custom. Once that's done, you can try to eliminate the switch, but just starting out, you're asking for trouble. All of the other questions are addressed in our installation PDF on the Printables page.
