USBPrinterOutputDevice.py edit the cancel routine?


Recommended Posts

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


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._is_printing = False
        self._paused = False

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

        # 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


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,

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
