Pause.g Resume.g problems

Deluxe 600

Do you guys any ideas what can i do so that i can pause the printer and get rid off the stepper whine noise? The printer i built is very large and because i keep it at home cant be run over night. So i am trying to set up a pause state in which it doesnt make any noticable noise but can be resumed printing the next day. I would be very happy for any suggestions . And happy christmas to you all

Well you could make note of the XYZ position and then turn off the printer. If it's stable enough and doesn't drop the Z axis or something like that you could then use G92 X Y Z after power up to reset the current position to what it was before powering off.

As long as the print stays attached to the bed and the Z axis doesn't change to much you should be able to resume the print either from the power loss recovery save position or from manually editing the sliced gcode file to restart from where you left off.

You can try using M913 to reduce the motor current to a lower value while the machine is paused. Or just set the idle current lower than the default value of 30% in M906.

@dc42 The holding current now is "M906 X1650 Y1650 Z1650 E700 I1" so thats 1% right? I think it doesnt go lower than that.

@Phaedrux It is stable enough so even after power off it doesnt move. But my problem is that after i pause it and turn off the steppers it doesnt watn to home and also i found out yesterday that in the pause.g i switch off the hoend heater, but after resuming it doesnt go back in temperature. Any ideas?

Have you read this about the noise? I managed to reduce the whining on my Duet3 with this.

@Deluxe-600 You can put the tool in standby when pausing and then in active mode when resuming.
For example if you only have one tool in pause:

G10 P0 R20 ; Set standby temp of tool 0 to 20*
T-1 ; put tools in standby

And in resume:

T0 ; activate tool agin
M116 ; wait for all temperatures.

@Deluxe-600 With G92 to set the position you don't need to home.

For pause, isn´t

T-1 P0 ; deselect all tools but don't run any tool change macro files

& For Resume, isn´t

T R1 ; select the tool that was active last time the print was paused

even better?
Just asking...

Nice it works!....well kind of strange thing thats happening to me is that when i use the pause button, it works as it should. But when i press the resume button i still get the error "G0/G1: insufficient axes homed". Now the strange part is that when i use M98 P"resume.g" and THEN the resume button it works. Can someone please explain this?

Phaedrux

Is your Z axis unhommed when you try and resume?

Deluxe 600

@Phaedrux
Yes, im still trying to do it with turning the motors off and then rehoming on resume. And it works just not by pressing the "resume" button. I have to use macro M98 P"resume.g" for it to work. After i apply the macro i pres resume button and it works as it should.

; resume.g
; called before a print from SD card is resumed
G28 X Y ; home X and Y
G1 R1 X0 Y0 Z5 F4000 ; go to 5mm above position of the last print move
G1 R1 X0 Y0 ; go back to the last print move
M83 ; relative extruder moves
G1 E10 F3600 ; extrude 10mm of filament

Assuming this is still your resume.g you should add something there to home z as well as XY

Deluxe 600

Now my resume.g looks like this

T0 ; activate tool again
M116 ; wait for all temperatures.
M98 P"homex.g" ;
M98 P"homey.g" ;
G1 R1 X0 Y0 Z5 F4000 ; go to 5mm above position of the last print move
G1 R1 X0 Y0 ; go back to the last print move
M83 ; relative extruder moves
G1 E10 F3600 ; extrude 10mm of filament

@Phaedrux it works as it is. Now i am trying to figure out why is it not working trough the "resume" button but trough macro (M98 P"resume.g") it does. I thought that the button calls the macro just liek the command?

Phaedrux

Firmware version?

Deluxe 600

@Phaedrux RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)

Deluxe 600

The resume button uses M98 P"resume.g" right?

Phaedrux

I believe so, yes. The only difference that comes to mind is maybe which gcode stream the commands is coming through.

Deluxe 600

@Phaedrux What can i do to make it work properly? I would like to use the normal web control buttons. If possible
