Pause.g Resume.g problems

dc42

@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.

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

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

M107

I put M107 is the pause.g but the cooling fan still didnt turn back on . Dont understand why. Also i have tried the G92 but it didnt have any effect, when pressing the resume button the print head just went above the print and then i got the "G0/G1: insufficient axes homed" error again.

Here is what i changed

; pause.g
; called when a print from SD card is paused
;
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 X20 Y525 F6000 ; go to X=20 Y=525
M18 X Y E ;turn off X,Y,E steppers
G10 P0 R20 ; Set standby temp of tool 0 to 20*
T-1 ; put tools in standby
M107 ; FAN off

; resume.g
; called before a print from SD card is resumed
G92 X20 Y525 ; axis position
T0 ; activate tool again
M116 ; wait for all temperatures.
G1 E20 F500 ; 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
M106 R1 ; FAN on

Phaedrux

Don't put G92 into the resume.g file. As I said, put it in a separate macro and then run that manually before pressing resume button.

Deluxe 600

@Phaedrux Yeah that works. But i cant figure out that print fan, any ideas?

Phaedrux

G31 X0 Y0 Z1.45 ; set Z probe trigger value, offset and trigger height

You may want to add your X Y offset for your BLTouch. Unexpected things can happen if you don't.

@Deluxe-600 said in Pause.g Resume.g problems:

; Tools
M563 P0 D0 H1 ; Define tool 0

Try adding F0 to your tool definition to make sure it's using fan0 for the part fan.

Deluxe 600

@Phaedrux The bl touch has a mechanical offset so its ok, but thank you . I added the F0 to the tool definition (now looking like this"M563 P0 D0 H1 F0" correct?) . Doesnt seem to change anything, the fan still doesnt turn back up. Any other ideas what could i try? This is realy strange.

dc42

How did you set the fan speed before the pause: did you use M106 with or without the P parameter? If you used it without (the usual way that slicers generate it) then your pause/resume code looks OK to me.

Deluxe 600

@dc42 Its set by the Slicer. So no ideas? Ow man

Deluxe 600

Well didnt know this would be such a problem

Phaedrux

an you share a sample gcode file? What slicer?

Deluxe 600

@Phaedrux Hi.
Im using PrusaSlicer for slicing.
Here is a gcode i tried printing.
