Python End of Slicing operation Looking for a smarter code

Posted (edited) · Python End of Slicing operation Looking for a smarter code

Hello,

 

I'm sure there's a more elegant way to get the end of Slicing event. But I can't find it. Note : This code works but the use of timers is really not clean.  If you could suggest me a more elegant way to recode this little piece of code.

 

Goal : Load an STL file -> Start slicing-> Export the gcode and read it back into Cura

 

import time
from typing import cast

from cura.CuraApplication import CuraApplication
from UM.PluginRegistry import PluginRegistry
from UM.Mesh.MeshWriter import MeshWriter 
from UM.Message import Message

FileName="C:/Temp/Tube.stl"
FileGcode="C:/Temp/Tube.gcode"
	
Me = CuraApplication.getInstance()

# Me.deleteAll()
Me._openFile(FileName)

# time.sleep(1)
print("File loaded {}".format(FileName))

Me.backend.forceSlice()
Me.backend.slice()

i=0
while Me.backend._slicing:
    time.sleep(1)
    i+=1
    print("Wait ! {} s".format(i))

gcode_writer = cast(MeshWriter, PluginRegistry.getInstance().getPluginObject("GCodeWriter"))

# open wt Write and text mode
with open(str(FileGcode), "wt") as stream:
    success = gcode_writer.write(stream, None)
print("Save Gcode Ok {} !".format(success))

Me._openFile(FileGcode)

    perhap's a begining of solution with  QTimer()  and  isActive() but I don't know if it's really better than 

    time.sleep

      • 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.
