K1 with MK4 on PrusaSlicer unknown command issue

I abandoned OrcaSlicer for the moment and have moved to PrusaSlicer since I know that it is supported and should work with the MK4 version of 3DChameleon (love this name by the way).

I'm getting a strange error that stops the print from running. Has anyone seen anything like this in the past? I'm not at all convinced that this has anything to do with the Chameleon.

14:59:47 // {"code":"key61, "msg":"Unknown command:T0", "values": ["T0"]}

14:59:47 // {"code":"key61, "msg":"Unknown command:M302", "values": ["M302"]}

Can you include you g-code? I'm not an expert, but I'm guessing somewhere when it's trying to change to T0 (Tool 0 for the 3dC) a part of the line should be commented out where it explains what the g-code is doing. M302 is supposed to allow cold extrusion, but again it could be that something is supposed to be commented out.

I uninstalled PrusaSlicer and then deleted the folder that was still sitting there just to be safe.

I am at the same spot, seem mk4 firmware is not pausing long enough to bumb 7 times, mine is bumbing 6 times so there is the problem how do i puase it longer to get the 7 bumbs needed at the start of a print?

Adjust the delay command after the button press command. IE:

G0 Y3 F2000	; Press the Button
G4 P3300	; 7 Pulses to Reset Chameleon
G0 Y-3		; Release Button
G4 S3		; Give 3 seconds to home

You would increase the G4 P3300 to get the 7 pulses.
