Pause print message not showing?  

RE: Pause print message not showing?

Posted by: @teachtheprints

Using the pause print feature, the printer stops at the set layer height, but it doesn't actually show the message set in PrusaSlicer. Is that just not working on the Mini?

Prusa Mini FW 4.2.1 using PrusaSlicer 2.3.0 alpha 3

If that's relevant, i could upload the gcode.

As far as I know, the functions M117 and M300 and some others are not yet available in the Mini Firmware, but this does not affect the pause function, because only the output on the LCD is missing.

RE: Pause print message not showing?

Thanks for the clarification.

Initially, I had printed via Octoprint, where it completely ignored the pause function. Printing the same gcode via USB, it did indeed pause at the set level, just without the display instructions on what to do.

This is probably and issue with commands being recognized by octoprint.  

RE: Pause print message not showing?

I have come across this very issue today also on my MK3S.

Firmware 3.9.1 and alpha1 slicer

Everything works OK except message entered when sliced does not appear on LCD.

Not using Octoprint.

RE: Pause print message not showing?

I also have a MK3S (FW 4.10.0-4481) that does not show the pause message...

The GCODE contains:

;PAUSE_PRINT
M117 Place Mk3 insert
M601

The message "Place Mk3 insert" is not displayed on the LCD screen (at least not for long?).

In Pronterface, the gcode M117 works OK:  couldn't resist trying "M117 Hello World!".  So the MK3S can handle the gcode, just not whilst pausing during a print it seems?

Perhaps it's affected by a previous command or something?  Here's the above, with more gcode either side of the M601:

; stop printing object FrontBadge id:0 copy 0
;LAYER_CHANGE
;Z:0.85
;HEIGHT:0.05

Not sure about the preceding "0.85" ?!

RE: Pause print message not showing?

It's an old thread, maybe you have already found a solution.

I have the nearly same issue on Prusa MINI+: I want to show the next color on the display before M600 (Change Tool).
I solved it with the following code. Maybe you can adapt this to your needs.

M601 ; Pause
M400 ; wait until all moves are completed
; color notification
M117 Next color is {extruder_colour[next_extruder]};
G4 S4 ; wait 4 seconds
M600

BUT than you will get an other issue. You can not post such a GCODE-file to printables, Printables doesn't allow code M400 in GCODE-files. I don't know why.
