M226 Pause Gcode ignored

totalitarian

I think you are right. It worries me it says not to use M25 code to pause the print in the currently printing G-code file though

Phaedrux

Yeah I'm not sure what the real intention is there.

You might be able to find some more context by searching the forum for M226 and M25. I know it's been discussed a few times. @dc42 would have to answer on the best way to implement a pause for the Mosaic Palette. Perhaps better support could be implemented if what's available doesn't already fit the need.

M25 is an asynchronous pause (i.e. pause as soon as possible). It used not to work inside the GCode file being printed, but I fixed that about 2 years ago. So it should be OK now.

Whereas M226 is a synchronous pause (i.e. wait until all preceding moves have been completed, then pause), and only works when used within the GCode file being printed.

Thanks, M25 indeed pauses. How to resume the print from DWC though?

Pressing the Resume button should work, just as for any other type of pause. Doesn't it?

totalitarian

@dc42 The resume button doesn't appear when the command is sent via usb

dc42

Like I said, M226 on!y works from within a file being printed from within the SD card.

Phaedrux

You could create a macro to send M24 to resume.

I've decided to allow M226 (and M600) even when no SD card print is in progress. This will allow it to be used in GCode files streamed over USB as well as within SD card print files. I'll implement this in 2.02RC6.

@dc42 Does that mean this will now work on a macro too? I found that M25 and M226 both get ignored in macros at least when run within DWC.

@dc42 You sir are a true gentleman. Thanks

M25 should already work from within a macro. Please try it again.

I've recently run into an intermittent problem, where hitting 'resume' from the DWC after an M226 (manually inserted in gcode file) will sometimes drop the Duet Ethernet (v1.03) from the network. This is similar to what others have described, other than it isn't guaranteed to fail. Unfortunately, when it does, the build is ruined. Yesterday, resume worked once and failed twice. I'm running 2.01.

My pause & resume macros are pretty much stock from the configuration tool.

Pause.g:
M83
G1 E-3 F3600
G91
G1 Z10 F5000
G90
G1 X0 Y130 F6000

Resume.g:
G1 R1 Z5 F6000
G1 R1
M83
G1 E2.5 F3600

Thanks for any suggestions!

Please try the just-released 2.02RC6 release (carefully - and read the upgrade notes) because this may have been be fixed already.

PlasticMetal

Thanks, David. It worked three times yesterday with the new release, so hopefully it's good to go.

Now to just find a quality heater cartridge...

@dc42

OK I tried again. I did the full update to RC6 yesterday and this still happens:

Error: M25: Cannot pause print, because no file is being printed!

I'm calling the macro by clicking the button in DWC

Calling which macro?

JRDM

@dc42 it's in a macro I wrote that's in my DuetM's standard macro folder.

dc42

You mean you have M25 in a macro, and you are invoking that macro from DWC or PanelDue? I've just tested that, and it works for me.

JRDM

@dc42 Yes. To test it in isolation, I just now put M25 in its own macro to test it by itself. I invoked it by clicking it from the DWC Machine Control panel, the User-Defined Macro list and I still get:

M98 P"0:/macros/Pause"

Error: M25: Cannot pause print, because no file is being printed!
