Stack Overflow error when running G32 from gcode print file



  • Hello...

    I've worked my way through most Z probe/FSR issues, and it all works, until, I try to add G32 to the start code in my slicer. When that code is run, it hits the G32 line then gives me an "insufficient axes homed", then a bunch of Stack Overfows. It then continues with the rest of the code, which goes terribly wrong...

    The calibration works when I hit the button or run G32, and there is a G28 in the bed file, all work, but when G32 is run from the Gcode, no go.

    Here are some relevant files...

  • It was the M120 beep commands I had in there to warn me to remove any ooze before the print starts. On the Rambo board, M120 is a beep, not so on this one, it is something else entirely. When I redid the beeps with M300's, all works.

    First test print running now. Damn that thing is quiet. Well, the motion anyway. The fans not so much. I just need to find quieter 30mm fans. The printer is 3 feet behind my head, and I need to keep looking over to make sure the thing is still moving.

    Sadly the Marlin developers are not good citizens of the RepRap community, because they ignore the common repository for G- and M-code allocations for repraps at https://reprap.org/wiki/G-code. In this case they ignored that fact that Adrian Bowyer had already allocated M120 for push/pop when they decided to use M120 for a completely different purpose. Anyway, I'm glad you identified the problem.

    Lots of us find we need quieter fans after upgrading to Duets! The Noctua fans are very quiet, but sadly not yet available in 24V versions.



  • Nor are they available in 30mm (or 25). I have a couple of the 40's, I may try to design a duct for them, although there may be something floating out there already.

    Thanks

  • Actually reprap G-code doesn't show M120 as beep in any firmare. Marlin is shown as M300, just like RRF.

    This is the best 30mm fan I've been able to find. It's worth the cost as far as I'm concerned.

    It's quiet, moves enough air and has a high mean time between failure.

    @dougal1957 odd. Here's the part number to search for. Perhaps because it's the Canadian site?

  • And for those in EU you can get them here (Prob other places as well but I got mine here)
