exceeding maximum extrude distance.
Hello, just got my 3d chameleon setup on my ender 3. Used the gcode generator for mk3 mode 2 and have my chameleon in mode 2.
This is my tool change G code:
; Auto generated 3D Chameleon Mk3 Tool Change GCode for PrusaSlicer
; - 3D Chameleon Mk3 Tool T{next_extruder} -
;begin switch from extruder {previous_extruder} to extruder #{next_extruder}
M117 Unloading Tool T[previous_extruder]
M82 ; turn absolute distances for the extruder
; unload extruder {previous_extruder}
G92 E0
; go to holding position to unload the stock extruder
G0 X103.5 Y207 F2000 ; <<----- EDIT THIS LINE TO SET THE INITIAL LOCATION OF THE BUTTON
; if this is the first load, then don't unload
G91 ; move to relative mode
M82
{if previous_extruder>-1}
; cool (and size) in 1.8mm tube

G0 E-10 F600; slowly allow it to cool
G0 E1 F2000 ; blob elimination

G0 E1 F4000 ; quickly ram the filament to shape it
G0 E-10 F4000 ; quickly retract the filament to shape it
G0 E1 F4000 ; quickly ram the filament to shape it
; back to 1.8 constriction
G0 E-50 F4000 ; quickly retract the filament to shape it
G0 E-80 F100; slowly allow it to cool
; turn the fan off
M107 ; this printer has the fan in the way, so turn it off

My problem is when it goes to change color I get an error in klipper "move exceeds maximum extrustion"
Any help to fix this? Also, I need to increase the load and unload distance as my extruder is not loading or unloading quite far enough. Which lines in the Gcode do I edit for that?
Yes, there should be no M82 commands... just make them all M83 commands. The printer should always run in M83 mode.
