Posted (edited) · USBPrinterOutputDevice.py edit the cancel routine?

Hi

UM2 with the + upgrade kit

Firmware 3.3.0

Cura 4.11

 

When printing and Aborting from a USB session, the bed does not lower but the head will home to the corner. If the cancel action is somewhere on layer 1-10ish the head hits the aft buildplate clip (because its not lowering the bed).

 

USBPrinterOutputDevice.py file shows:

 

def cancelPrint(self):
        self._gcode_position = 0
        self._gcode.clear()
        self._printers[0].updateActivePrintJob(None)
        self._is_printing = False
        self._paused = False

        # Turn off temperatures, fan and steppers
        self._sendCommand("M140 S0")
        self._sendCommand("M104 S0")
        self._sendCommand("M107")

        # Home XY to prevent nozzle resting on aborted print
        # Don't home bed because it may crash the printhead into the print on printers that home on the bottom
        self.printers[0].homeHead()
        self._sendCommand("M84")

 

Im not a code expert but I think something can be added at the end of this. Could someone point me in the right direction?

 

Thank you,

 

Patrick
