I was wondering if you could provide more pictures of a prusa mini 3d chameleon set up. I followed all the instructions, but it doesn't seem to work. It hits the sensor and looks like it would change. But with my motor attached to it (from the prusa) it doesn't drive anyfilament through the system at all.
Just would love to see some close up pictures just so I know If I have everything set up the right
I get this error. Note I have cleared the temp file location. But slicing it always creates a new temp file. And there's no way to delete it while the file is open to then export. What do you recommend? Also Do you think you could send me a picture of the prusa mini setup. In the videos I just cant see the back of printer to see the placement
Also, note, that if you're using this with a direct drive, you need to make sure you have the post processor installed.
Here's the procedure for it here: https://www.youtube.com/watch?v=4mpSn5O6pAQ
With the Prusa mini motor set up as the extruder, pressing the button won't drive it... use the Prusa Mini's menu to move the filament instead. Also, you can't use the Auto generated gcode, as that is expecting the button to control the extruder, but since it's hooked up to the stock motor, the normal gcode commands are needed for it.
Here is the tool change gcode I use for mine: ; - 3D Chameleon Tool{next_extruder} -
