Heaters won't shut off after a print with 1.19
-
Those commands should still work. Is this reproducible?
-
I've been trying to tune retraction and heat with the temperature issues I've been having on my corexy with correctipn a 1000mm Bowden tube and everytime it finishes the print it's still at temperature. When I get back from work today I will be trying again. So far I'm on my 23rd attempt with same results, heaters stay on after print finishes and blobs on corners.
Edit: if I hit pause print and then cancel. The heaters shut off.
Another edit: duet web control constantly disconnects every couple of minutes.

Please open the gcode file you are trying to print in a text editor, and post the last 30 or so lines of that file here (or more lines if there are a lot of comment lines after the last gcode commands). Or copy the gcode file to a file sharing site and publish the link to it here.

I just grabbed a clump of code from the end of the print I have been using

Thanks, I'll try that ending gcode on my next print.

I have reproduced this issue, and will prepare a fix for release 1.19.1.

I have tracked this one down. It's failing because M104, M140 and M300 are all commands that are deferred until the preceding movement commands have completed. However, the deferred command queue is only 8 commands long, and the number of M300 commands you have alone exceeds that.
The firmware should handle this case by executing the oldest queued move immediately so that no commands are lost, but that part evidently isn't working. We will fix it in the next release. Meanwhile, please add M400 before your block of M300 commands. That will force the firmware to wait for movement to cease.

@zakfarias. This is nothing to do with your heaters shutting off but I noticed that at the end of the file, you have an 8mm retraction just before ";layer end". Immediately after this, presumably in the end gcode the extruder is zeroed an then another 10mm retraction happens. So at the end of a print you are retracting 18mm of filament. That's quite a lot and could potentially lead to molten filament being drawn up past the heat break where it will solidify and could potentially cause a blockage. Just a thought…....

I did notice that when posting to DC42…however it definitely isn't retracting that much at the end. I am wondering if maybe the DUET is calling the print done before Simplify 3D end layer gcode starts...whoch would explain why adjusting the end retract and heated off isn't working. But how would it be doing that...haha so many unexplained mysteries this week on this machine.
Sorry didn't notice your post DC, I will edit as you say. Thanks!

Once done that edit that David recommended, you might want to take out that other retract because then it will be acted on.

OKAY So I ended up adding the M400 and then for fun said screw it and got rid of all the M300. Works like a charm now! Also dialed back the additional retraction to 2mm. So at least the heater safety issue seems to be resolved
