G32 in the beginning of my print gcode turns off heaters



  • I'm very new to duet or RRF and am just now trying my first prints on my cbot. I replaced a smoothieboard that i never particularly cared for. I'm amazed at how smooth/quiet it is.. i didn't know sound levels like this were possible!
    I heat my bed / nozzle up before running g32. After running g32 both heaters turn off… i didn't think much of that until i put it in the startup of my print gcode. Now as soon as the g32 finishes duet thinks the print is done.

    Is that normal? I've read a bunch of threads where people do something similar so I'm thinking I'm doing something wrong or maybe it has changed recently?

    this is from my config.g

    M558 P4 X0 Y0 Z1 H5 F120 T6000 I1 ; Set Z probe type to switch, the axes for which it is used and the probe + travel speeds
    G31 P500 X-30 Y0 Z1 ; Set Z probe trigger value, offset and trigger height

    I think something in your bed.g file must be turning the heaters off. Please share the contents of bed.g.

    That looks OK to me. Please post the contents of your homeall.g file, or homedelta.g if it is a delta printer.



  • I added an S1 to one of the G1 commands because otherwise it would ignore the endstop and keep running in.. this is a corexy setup, fyi

    That looks OK to me. I don't see any reason why G32 would turn your heaters off, so I suspect that you are getting a heating fault. Are any messages displayed on the GCode Console page of the web interface? Does the web interface show either of the heaters as being in an error state?
