@demonio669 said in Simplify3d 4.0.1 gcode causing Duet to mess up:
@ElmoC, I have this start gcode for Simplify, hope it work for you
T0
M140 S[bed0_temperature] ; set bed temp no wait
M104 S[extruder0_temperature] ; set extruder temp no wait
M106 S0
G28 ; home all axes
M116 ; wait all temps
M98 P/macros/CleanNozzle ; clean the nozzle
Not familiar with the M116 command. Will look into that. Thanks.
Well, while I did get it to work a couple times, when I went back and performed the steps here https://duet3d.com/wiki/Using_mesh_bed_compensation, the bed only moves away from the nozzle. I tried Z at 5, 10,15, and 20, all with the same results. 
EDIT: I restarted the printer and homed all axis. I then moved Z to 10, deployed the probe, and tried G30 S-1 again. This time it worked. So one of those commands in the steps is causing the issue. Will see if I can figure out which one.
EDIT 2: It seems the problem is with the M208 Z-3 command. This is setting the maximum Z travel to -3. I believe the command should be M208 Z-3 S1 to change the minimum Z travel.
