You may need to start quoting your file names when calling macros. It should be fine in standalone mode, but in SBC mode it is required and may be required in standalone in the future.

It's a long shot, but still worth a shot.

Are your drivers actually getting hot to the touch or are they spurious warnings? Printing is working correctly, right?

moth4017

@phaedrux
No they are not hot and i did a 8 hour print and they were ok , i only get that error after the "Pause, Cancel"

Phaedrux

I assume you're in stealthchop mode for the stall detection?

Can you zip up the entire sys and macros folders and share them with me, either upload them here but first change the file extension to .txt or use a file sharing cloud service. I'd like to get a complete look at what's going on with the actual files.

Thanks, I'll have a look tomorrow.

Can you try copying your cancel.g to stop.g?

Hi

I just noticed in your pack of files that cancel.g has a leading blank space character.

Do you have a start.g file? If not, can you create one and add G28 to it?
That should make sure all axis are homed before the sliced gcode is executed.

I think the over temperature warnings on drivers 0.4 and 0.5 may be related to stall detection on the Z axis.

@phaedrux
Will do ill test now so you have results in the morning

moth4017

@phaedrux
Interesting after removing the "space " from the "cancel.g" file the commands now work
also the over temperture errors seem to have stopped, will do more checks to confirm

moth4017

@phaedrux

After testing , I can confirm all the above issues are caused by the space in front of the " Cancel.g" file , including the errors below.

Thanks for the help. im guessing you will want to trap this issue some how, help happy to help test if needed .

Well I think what's happening here is that with the cancel.g basically missing when the print is canceled it's getting sent M0

https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m0-stop-or-unconditional-stop

Then when trying to print again the machine is not in a ready state. When the motors are in stealthchop mode they require a short tuning move and I guess that's not happening, hence the errors.

It would be best to have a cancel.g and stop.g file present with the commands you wish to happen. Use M0 as your slicer end gcode, then have all your ending commands in stop.g.

You can also use a start.g file that has any preparation commands you want. Like homing the printer, pre-heating, etc.

That should give you more predictable behaviour.
