hello makers, since a short time, my a350t doesnt execute the stops for filament changes. i checked the gcode for M600 and the code is there, but my printer doesnt pause anymore. any idea what is causing the problem? thank you!!

hello, thanks for you reply. no i start the print with luban over wifi. i never used M412 S1. yes, i use the single extruder that was shipped with the a350t. the thing is that about two weeks ago i had no problem printing with color changes. i will cut some filament and test if the runout senso…

I also just found out M600 doesn’t work like it use to. I found Profile - raypfountz - Snapmaker: where creation happens said to use M76. I tried M600 followed by M76 and that worked. I didn’t try M76 alone. I had previously used M600, but that was a couple years ago. Try the M76 and see.

hmm, that means i always have to open the gcode and change it manually? but how did it change? i havent updated the firmware

runout sensor is working. it stopped after filament was empty

Interesting, I wonder why this isn’t a part of SMFix if it’s a thing that needs to be done. Perhaps @macdylan never used M600?

Also, you’re using Prusaslicer, you can edit the “pause print” custom gcode under Printers > Custom G-code (you may need to enable advanced mode to get this to show up). You could add M76 there. M600 might only work when printing from the touchscreen or luban, if you’re running from octoprint, sinc…

Weird, M76 doesn’t really do anything: Snapmaker/Snapmaker2-Controller/blob/9bf2233c0262516d7dcbe46d6f28e28da7d9f8c5/Marlin/src/gcode/stats/M75-M78.cpp#L42C1-L55C2 /** * M76: Pause print timer */ void GcodeSuite::M76() { S…

I have M76 as “Pause the print job timer” so I’m not sure why that works with the M600, but it seemed to do it where M600 alone didn’t. I just went back to the M600 that ‘worked’ (2/2023) and noticed I actually used a M0 - M600 combination. M0 is “Unconditional stop” so I’m not sure if it was M0 or…

There could also be more to that code, most likely the systemservice is causing the pause stuff to run, but planner.synchronize() could be kicking off a chain of events that causes the m600 to actually execute, or something could be listening to the terminal for that echo.
