Pause.g Resume.g problems

A Former User

@TypQxQ said in Pause.g Resume.g problems:

@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. 

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?

Is your Z axis unhommed when you try and resume?

@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

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?

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

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

@Deluxe-600, what happens when you press the Resume button?

Deluxe 600

@dc42 The printing head goes back to the saved position lowers to the print and then "G0/G1: insufficient axes homed" error and cancels the print. I can change whatever i want in the "resume.g" file but nothing changes.

Deluxe 600

This is just weird. If i create a macro for resume in which i have :

T0 ; activate tool again
M116 ; wait for all temperatures.
M98 P"homex.g" ;
M98 P"homey.g" ;
M106 P0 T1 ; restores the previous fan speed
G1 E10 F3600 ; extrude 10mm of filament
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

It does all it should but then it just moves above the print and pauses.
Then i have to push the "Resume" button in the interface. It homes again and then starts printing....but if i dont run the macro first it doesnt home or wait for the tool to heat up. It just moves above the print and then throws an error messeage. I realy dont know what to do . Im fighting it for the last 4 days.

The button is checking to see if any axis are unhomed and will not run if it's unhommed. Which is why when you force resume.g to run and it runs the homing macros you can then use the button the second time.

Can you try splitting out the homing from the resume.g file?

As I suggested before, create a macro that contains a G92 command to set the current location for X Y Z. If your pause.g moves the axis to a certain location, and your axis stay stable when the motors are off, then you can use that same position. No rehoming needed.

Then you can run that macro to set the axis as homed, and then you can use the resume button. Remove any homing calls from resume.g.

@Phaedrux I will definetly try that and let you know. CAn i have one more question? When pausing i would like to turn off the part cooling fan but also somehow save the value it was on so i can resume cooling when resuming the print. I was trying to figure it out using M106 R1 or R2 but no luck so far. Thanks

Phaedrux

I would have thought M106 R1 or R2 would have worked. How are you turning the fan off in pause.g? M107?

Deluxe 600

@Phaedrux M106 S0

Phaedrux

Try using M107 in pause.g to turn off the fan and then M106 R1 to return it to it's last speed in resume.g
