Marlin: [BUG] After Bed Leveling LCD stays in Print mode

[reloxx13]

Description

If i level the Bed with G29, the LCD stil says "Printing" and it shows only the printing menu items.
While in Octoprint i can start a print w/o problems.

Steps to Reproduce

This is my level code in octoprint Bed VIsualizer which i use to level.

M190 S70 ;wait for heat
M155 S30 ;lower temp reports
G28 ;home
G29 T ;ABL
M500 ;save mesh
M501 ;load mesh
M155 S3 ;default temp report
M140 S0 ;stop heating

Expected behavior:
Printer LCD shows Non-Printing Mode menu

Actual behavior:
Printer LCD shows Printing Mode menu

@reloxx13 is this still a problem?

[reloxx13]

yes

[boelle]

thinking of this, does it only happen when printing/leveling from octoprint?

[AndKe]

@boelle yes, in my case, it is the only way I see it happen as the levelling is in the start of any job, right in the gcode.

[boelle]

i print from octoprint also but i dont do level before each print, only when print shows its needed

i have #define RESTORE_LEVELING_AFTER_G28 and the only thing i need to check on LCD is that bed level is enabled, if it says off i just click that to make it say on

normally i only do this after i power up the printer and after a disconnect,

and even if i home its enabled, doing level before each print is kind of overkill,

but this does not mean that there is not a bug, its just to figure out if its a problem with marlin or octoprint

[reloxx13]

yes, i use octoprint.

i only level if needed with bed level visualation tool.

yes, still happens, had it again few days ago.

sometimes i level and want to change filament afterwards oder move z up to clean the bed and i cannot cause it stays in print mode (print mode menu and status text "printing").
had this again a few days ago.

@reloxx13 dusting off this one, is the issue still there?

[reloxx13]

+

[boelle]

and that means?

[reloxx13]

positive :D

[boelle]

oki, a shame its still there :-(

[boelle]

is the issue still the same with all the updates in the last 43 days?

[boelle]

btw, who can confirm there is an issue? use the same configs as OP and the same hardware if possible

[reloxx13]

there were leveling changes last days and ill have to re-test.

[boelle]

oki. looking forward to that :-D

[boelle]

@reloxx13 did you retest?

[reloxx13]

still happening.

e.g. menu shows stop/pause sd print, but printer is idling after bed leveling.

load/unload text is also switched,
load shows text for unload, unload shows text for load, since months.
german fw latest bugfix 2.0.x from today.

i wont answer any further questions if its fixed or not. ask the devs or tell em to properly use git and #issue id in commits.

If you don't plan to be involved in the solution it's likely it won't be fixed unless someone else with the same issue gets involved to sort it out. I personally can't reduced this issue.

[boelle]

@reloxx13 i agree here, you are the only one with this issue so far, i cant reproduce it either and tried many times but it works every single time

and you last 2 lines of comment are kind of uncalled for and belongs to where i call it "nasty"

[thinkyhead]

last 2 lines of comment are kind of uncalled for

Well to be fair, this issue has lingered a long time without a single human capable of investigation coming along to look into it. We could really use more initiative in that area. It can't all fall to me.

@reloxx13 — At a glance, the problem seems to be that you might need M104 S0 (after M140 S0) at the end of your script. Please confirm if this helps!

[thinkyhead]

@reloxx13 —

Ach, that last suggestion is sensible, but you deserve more detail. So here's what I can tell you:

• It's unusual to use a G-code script from host to do G29 bed leveling.
• Marlin uses hints and clues to detect that a print job has begun/completed (heater turned on, print job timer started, etc.), but the host can help with some explicit commands.

So, if M104 S0 doesn't solve it, see if it helps to add M77 to the end of your script.
It also might help to add M117 to the end of your script, after that.
If these don't do the trick, we can look further.

[thinkyhead]

To remedy this (for future Marlins and beyond) we should take account of bed heating and not just hot-end heating in our evaluation of print job start and stop. Contribs wanting to have a go at this patch should look for PRINTJOB_TIMER_AUTOSTART in M104_M109.cpp and contrast with M140_M190.cpp.

[Vertabreak]

strange as i used a script for UBL on both octoprint and pronterface and it does not produce this effect. i did have it turn off the heat at the end might be why.
