3.2 SBC cancel print not working w/ missing/blank cancel.g

Heartleander81

There is a picture oft the DWC .
Print is at layer 71 and filament only used 0.4mm, but must ~100mm used at this layer hight.

I hope you understand what i mean. My english is not the best

Hi,

This is a long shot but create an empty cancel.g file and see if that makes a difference.

@fcwilt Will test it after work. But just think that I have an error somewhere in a file. After successfully printing the file, the problem was that the next print did not work either. It only worked again after restarting the Pi. That's only since I updated from 3.1.1 to 3.2.0

@Heartleander81 said in Problem after cancel print:

If I have to cancel a print and start this or another, the extruder no longer feeds filament.
Only when I reboot the Raspberry Pi 4 does the pressure go back to normal.

Can you try describing again what exactly this means? I'm having a hard time understanding the problem.

Does the printer try to resume the print but the extruder motor doesn't turn?

Does it just sit there?

Is the heater at temp at that point?

@Phaedrux
I start a print.
For example, a component comes loose.
Then press pause and release the pressure.
Change something on the slice or try to reprint.
Then nothing is extruded during printing.
When I restart the Pi, it prints normally.
But today I was able to determine that this problem also occurred even after a successful print. That's only since the update from 3.1.1 to 3.2.0

After Bed and Nozzle is on temp make my Printer Homing.

Did you try creating the missing cancel.g?

This post is deleted!

Heartleander81

Is the same with empty cancel.g

Phaedrux

Do you have a T0 command in your slicer start gcode?
Is your tool still selected after canceling?
Can you try putting some commands in your cancel.g?

Example:

; cancel.g
;
; Run when the print is paused, and then canceled.
;

G10 P0 R0 S0		; Set hotend temp to 0
M140 S0			; Set bed temp to 0
M106 S255 		; Fan at 100 to cool nozzle and bed
M220 S100		; Set speed factor back to 100% in case it was changed
M221 S100		; Set extrusion factor back to 100% in case it was changed
M290 R0 S0              ; clear babystepping
G28 XY			; home XY
M84			; turn off steppers
G4 S60			; wait 1 minute for nozzle to cool
M107			; turn off the fan

Now is working with this config.

Can you tell me why?

What config? Did you mean to post one?

@fcwilt i mean the config post from phaedrux

Phaedrux

You mean you added those commands to cancel.g?

I'm thinking there is an issue with missing or blank cancel.g files and the firmware isn't doing the expected default behaviour.

Thanks for confirming that adding a cancel.g with commands allows it to work. I'll flag this for further investigation.

@Phaedrux I doun't now why, but on second test, the same bevore. I test at saturday more cycles. I think the problem is at my side.
I give you Feedback at saturday night ore sunday morning.

@Phaedrux
Thanks for your help. But i doun't find out what is. I have downgraded to 3.1.1

When the next 3.2.x stabel comes out i test it.

Heartleander81

I found the mistake. It was the slicer. I accidentally swapped relative and absolute extrusion. As a result, the skirt was still printed and nothing came out of the nozzle during the actual printing

Phaedrux

Thanks for the update.
