Unknown Command popups (Prusa Slicer)

[dexter323i]

The display is TFT35 V3.0, latest FW. I use Prusa Slicer. I printed from Display SD port, and during the print, it kept popping up messages telling echo: Unknown command. Two examples:
"M73 P58 R3" ok
"M73 Q30 S5" ok

hi, according to http://marlinfw.org/docs/gcode/M073.html, M73 is a set current print progress percentage for LCD(LCD12864/LCD2004 etc...) manually, it's useless for touch screen,You can enable LCD_SET_PROGRESS_MANUALLY in Marlin's Configuration_adv.h to support this command, or disable this commad in your slicer

M73 is used to set the progress bar value like this M73 P12 to set at 12%. There are extra variables in your g code file for M73 command which are not compatible with marin firmware.
You need to check your slicer setting and gcode file.

Okay, I accept M73 P__ is the standard format, and Q R S are Prusa specific, not standard parameters. But can you modify the FW, not popping up this window? Hide the error, that's all. This could solve the issue.

I guess Marlin 2.0 FW does not now this advanced feature also, but the factory Ender 3 display not pops up errors. Just steps over it.

@dexter323i Disabling the notification in TFT will not disable it in printer.
you can disable the M73 command in prusa slicer
make sure Supports remaining times is unchecked in prusa slicer settings as below:

@guruathwal thank you so much! This checkbox solved the issue!

M73 R support was added to Marlin 15 days ago: MarlinFirmware/Marlin#15549

Marlin’s documentation needs a refresh, so it’s not listed.

I have written a python script and a windows droplet for this purpose. You can drop your gcode file onto the M73exDroplett and it removes all M73.
