the top and bottom holes on the left hand side are both moving together, this has nothing to to do with the Gcode but, Gcode as follows ; 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 X232 Y116 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-20 F4000 ; quickly retract the filament to shape it G0 E-10 F600; slowly allow it to cool G0 E1 F2000 ; blob elimination ; back to tip size G0 E-20 F4000 ; quickly retract the filament to shape it G0 E-10 F600; slowly allow it to cool G0 E1 F4000 ; blob elimination G0 E-10 F4000 ; quickly retract the filament to shape it 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 ; retract it back out of the extruder G92 E0 G0 E-95 F2000 G92 E0 G0 E-30 F2000 G92 E0 ; ok - out of extruder - press button to remove it all the way G91 ; move to relative mode M82 ; we skipped to here if it was extruder -1 {endif} ; load extruder #{next_extruder} M117 Loading Tool T{next_extruder} ; press the button to select the new extruder G0 X3 Y3 F2000 ; press the button {if next_extruder==0} G4 P500 ; dwell for .5 seconds - adjust this to match your machines single pulse time {endif} {if next_extruder==1} G4 P1000 ; dwell for 1.0 seconds - adjust this to match your machines two pulse time {endif} {if next_extruder==2} G4 P1500 ; dwell for 1.5 seconds - adjust this to match your machines three pulse time {endif} {if next_extruder==3} G4 P2000 ; dwell for 2.0 seconds - adjust this to match your machines four pulse time {endif} G0 X-3 Y-3 ; back off the button G4 S15; wait for it to happen ; adjust this time to match the actual tool change time - subtract the time it takes to load for the last 1" into the extruder G0 E50 F1500 ;      << -------   ADJUST THE E50 VALUE TO STOP IT RIGHT AFTER IT LOADS INTO THE STOCK EXTRUDER (50mm is the default) ;                ADJUST THE F1500 TO MATCH THE SPEED OF THE FILAMENT FROM THE 3D CHAMELEON ;                NOTE: This defaults should work, but you can always tune them to be perfect. G4 P1500 ;          This is just a half second extra reloading time... just to make sure G92 E0 G90 ; move back to absolute mode M83 ; but make sure the extruder stays in relative ; reload filament all the way into extruder G92 E0 G0 E30 F2000 ; <<<<<----------- EDIT THIS DISTANCE TO FINE TUNE THE FILAMENT LOADING TO STOP BLOBBING OR UNDEREXTRUSION G92 E0 M83 ; turn relative distances for the extruder M117 3D Chameleon Tool T{next_extruder}
