[BUG] SD Print Filament Change and Pause Freezes TFT, No resume working.

[sharonna511]

Describe the bug
No pause method is working.
Tested:
SD Print > press pause onscreen, head goes park, tft button switches to continue, but is then not responding.
SD Print > M25 Pause in GCODE, head goes park, tft button switches to continue, but is then not responding.
SD Print > M600 in GCODE head goes park, filament gets unloaded, peeps a lot, tft button switches to continue, but is then not responding.

Any help to fix that appreciated, Thanks.

To Reproduce
See above

Expected behavior
On onscreen or M25 pause, resume should be working.
On M600 resume should be working.

Printer (please complete the following information):

• Firmware version: # Anycubic i3 Mega / Mega-S Marlin 1.1.9 by davidramiro, self compiled
• Printing method: SD
• Model: i3 Mega

Cannot reproduce any of those issues, anything special on your setup? Since you are using a self-compiled version, anything noteworthy that you changed? I'd recommend trying again with a precompiled release, at least that's what I am testing on.

[sharonna511]

Yeah its strange, i figured you would have noticed such things, but it is so
Changed, just basic stuff, tmc2208 reversed plugs in printer, commented out the filament runout sensor, removed and add a few entries in special menu. But i must say that even before with the anycubic firmware when i put M25 pause in gcode resume did not work, tft just never displayed resume. Maybe i have a buggy or different tft version ?

[davidramiro]

before with the anycubic firmware when i put M25 pause in gcode resume did not work, tft just never displayed resume.

Yes, that is a feature I built into this version.

commented out the filament runout sensor

Not sure if that might cause it, but try again with it enabled.

Also, you can uncomment ANYCUBIC_TFT_DEBUG in Configuration.h to get some more info via USB in the terminal.

[sharonna511]

thanks i will test and report back.

[davidramiro]

Could you find anything out?

[sharonna511]

I did not have time over xmas/new year. I tested it now.
I had filament sensor and tft debug uncommented. Also i had the filament sensor connected and filament was in it.

m25 in gcode > parks, display says pause not continue, on press on pause not responding, then i press stop, the message came with ok and back arrow, pressed back arrow, but it stopped then, as if i pressed ok

So i don't know what is wrong there, would be nice it is was working, but it is not high priority for me, since i can always use my Kossel for filament swap things at the time.
But it is very strange...

[coolio986]

I also have this same issue described above. Tested with the same gcode.

[andreymukha]

I and many people from the Russian chat of Anycubic I3 Mega have this problem as described above

[JensW2000]

before with the anycubic firmware when i put M25 pause in gcode resume did not work, tft just never displayed resume.

Yes, that is a feature I built into this version.

Here the same problem. Neither Continue nor Stop works when the printer is paused.
This affects both - the "Pause button" and M600.

The error is gone when
#define ANYCUBIC_FILAMENT_RUNOUT_SENSOR is declared again
