Cancel.g doesn't do what I want :-)



  • Hi there,
    am I right that after cancelling a print job (after pause was pressed) the cancel.g file is started? Because the printer doesn't do what I tell him in this file...? Or what subroutine is started after cancel is pressed?

    greetings kuhni



  • Correct, I have mine set to turn off hotend and bed then move X and Y to 0.

    What are you trying to get it to do?



  • Really strange... Tried to switch of the part cooling Fan (m107 and tried also M106), a G1 X320 Y320 and also wanted to switch of the Stepper Motors. But the only thing that is done is a G1 X320 move and X and Y are disabled. The part cooling fan stays enabled and, the z motors also and the Y movement doesn't work...?



  • @kuhnikuehnast
    Can you post your cancel.g and also pause.g?

    On my machine i'm doing similar things and they are working as expected

    I use

    M104 s0 ; hotend off *
    M140 s0 ; bed heat off*
    M106 s0 ;fan off
    G1 x0 y0 f5000 ; move hotend away from print*
    M84 ; motors off

    “*” means I also use it in my end script in Slic3r



  • The usual dumb question ... you named it "cancel.g" ...? Because I think it is case sensitive.

    I have this /cancel.g and it works:
    ; called when a print is cancelled after a pause.
    M106 P0 S0 ;Set fan 0 (part cooling fan) to 0%
    G28 ; home all towers


  • administrators

    Can you confirm that the cancel.g file is in the /sys folder of the SD card?



  • Maybe you have something in your pause.g which prevent calling cancel.g?

    M106 P0 S0 ;Set fan 0 (part cooling fan) to 0%
    G28 ; home all towers

    the fan is disabled even if it is a thermostatic fan?

    I don't know, I didn't try it yet



  • cancel.g is in the /sys folder (same folder as config.g)
    This is my cancel.g file:
    ; stop.g
    ; called when a print is cancelled after a pause.
    M140 S0 ; heated bed heater off (if you have it)
    M104 S0 ; Extruder off
    G91 ; relative positioning
    G1 E-1 F300 ; retract the filament a bit before lifting the nozzle to release some of the pressure
    G1 Z+0.5 E-3 X-20 Y-20 F9000 ; move Z up a bit and retract filament
    G90 ; absolute positioning
    G28 X0 Y0 ; move X/Y to min endstops so the head is out of the way
    G1 X320 Y320 ; parks X head pushes bed out to front so you can pull part
    M106 P1 S0 ; fan off
    M84 ; steppers off

    and this is my pause.g

    ; pause.g
    ; called when a print from SD card is paused
    ;
    ; generated by RepRapFirmware Configuration Tool on Fri Mar 23 2018 20:49:13 GMT+0100 (Mitteleuropäische Zeit)
    M83 ; relative extruder moves
    G1 E-10 F3600 ; retract 10mm of filament
    G91 ; relative positioning
    G1 Z5 F360 ; lift Z by 5mm
    G90 ; absolute positioning
    G1 X0 Y0 F6000 ; go to X=0 Y=0

    Really strange...??? Any ideas?



  • btw: just found another file on the /sys folder called stop.g ? Where is the difference between these 2 files? (Also posted in the stop.g the same code as in cancel.g but with no effect... )





  • Just looked at the console:
    Cancelled printing file XXXX.gcode, print time was 0h 23m G0/G1: insufficient axes homed

    But there is no gcode that disables the steppers before???


  • administrators

    The "insufficient axes homed" may indicates that your homex.g or homey.g file isn't right. Try sending G28 X0 Y0 from the console and see if you get the same message.



  • M25 executes macro file pause.g
    M24 executes macro file resume.g
    M0 executes macro file stop.g

    I know that after I press ""pause print"" in DWC and press cancel, its executes macro file stop.g, which in my case includes these commands:

    ;Stop Printing (M0)
    G10 P0 S0; 	Turn off extruder heater
    M140 S0; 	Turn off bed heater
    M106 P2 S0; 	Turn off cooling Fan
    M300 S100 P500;	Sound beep using PanelDue buzzer, frequency Hz (Snn), Duration (Pnn) 
    

    I don't have cancel.g file in my sys folder,
    What am I missing?


  • administrators

    If you press Pause and then Cancel, it runs cancel.g. Whereas if the print terminates by executing M0 at the end of the file, it runs stop.g.



  • Thank you very much.



  • @dc42 tried G28 X0 Y0. This works just fine. Don't get any error messages and the extruder homes properly. Any other idea why this problem occurs?
    Here my homex.g:

    ; homex.g

  • strange thing is, that the cancel.g is exactly the same code as I use in the end-script in simplify3d. And there it works just fine!
