Will note that the M3D uses a specialized plugin, this is why this is in the plugin section.
When you say "Cura" do you mean the one that's embedded in OctoPrint or the stand-alone version?
I am using the standalone. The M3D, M33 FIO plugin comes with a full blown slicer and I am using that.
I know that OctoPrint's Settings -> Printer Profile for your printer includes various settings but it's possible that these are only used in the buttons as seen in the Control tab.
They seem to be set in th Cura settings parameters aswell in the "advanced" tab.
If you slice in the stand-alone version of Cura, then see if adjusting the printer's X/Y perhaps. Not sure exactly how it's bumping on your printer.
No idea. That is why I am asking
It might instead be necessary to go into your printer and to move the left end-stop switch rather than fussing with everything in the firmware/software areas. Many times when you choose to HOME the X/Y motors, it just moves left and back until either end-switch is in the TRIGGERED state as seen via the M119 report. Then the printer knows that this is the zero point. This may slightly reduce your print volume. So then you probably should reduce the maximum X/Y to compensate for the reduction you made on the other side of the printer... or not. (Try it and see if it still works.)
The M3D has no endstops. Its a strange printer.
Me, I tweaked the end-stops further out and then adjusted the maximums slightly more to add about 75 cubic mm to my print volume. It's the reverse of what you're doing.
I can't do that
