Welcome to the SeeMeCNC Community

I'm just getting an H1.1 going and am using a GnexLab controller for bed and extruder. I see the Slic3r gcode has gcodes for temp control. Is there any way to not have this output or do I have to search/replace the gcode file? Or will those gcodes just be ignored? I haven't actually tried to run the gcode yet, but looking at it (lifelong cnc guy, so reading gcode is in my blood!) if it's going to stop on those temp gcodes, it'll never go again!!

When I was using Mach3 originally I did not have to do any post processing on the gcode. Mach probably ignored those or passed them on to the controller, which ignored them.

OK, cool. I'll just have to give it a go and see what Mach does with the goofy stuff. This is what the offending gcode looks like:

M107
M190 P105 ; wait for bed temperature to be reached
M104 P235 ; set temperature
G28 ; home all axes
M109 P235 ; wait for temperature to be reached

No idea what M107 or M190 P105 would do unless one had written Mach m1s macros for M107 and M190 taking the Pxxx input.

Not sure what you meant by "passed them on to the controller". Isn't Mach the controller? If you mean TEMP controller, that and Mach, in my setup, aren't connected. The GnexLab controller is stand alone. Mach only controls the motion. I guess I can load the gcode and see if Mach complains!!

Thanks

Mach is the controller. I meant the BOB and drivers. Sorry!
