On Craftbot I’ve used the M600 command to manually inject pauses between layers for changing filament color.
I tried the same thing on my Snapmaker 2.0 and found that when it gets to the pause it moves odd the bed and it ejects the filament just like I want. Unfortunately the buttons for loading filament don’t come up on screen and there is no “resume” button. It has a “pause” button on screen. If I push the pause at that point it just freezes and can’t recover.
Any suggestions on how to do a hot swap of the filament on Snapmaker?
