Z-axis Home on Abort (Cura 3.0.4)

[mzemba 0]

I jumped from Cura 15 to Cura 3 recently, and I've been running into an issue where the "Abort Print" routine will end with a home of the Z-axis...which is a huge problem on printers that home Z on the bottom (potentially drilling your hot end into the aborted print).

I found discussion on the issue circa version 2.7 (here and here), and it seems to have been fixed. When I checked out my USBPrinterOutputDevice.py, Line 626 is commented, "# Don't home bed because it may crash the printhead into the print on printers that home on the bottom".

Is version 3 no longer using that file for the abort routine...? Are there any other reasons I would still be getting a Z-home when I abort?

In Cura 3.0, there's a bug where homing just the head actually homes all axes. This has been fixed for Cura 3.1. A beta of Cura 3.1 should be available in a week or so.

If you want to fix it yourself for now, change line 122 of USBPrinterOutputDevice.py:

 

self._sendCommand("G28 X Y")

Thanks! That answers that.

If I add anything to the USBPrinterOutputDevice.py, next time I open Cura it doesn't find the printer anymore. I have to remove the line, save the file and restart to go back. I am trying to add custom axys positioning when hit abort. Please advice.
