Getting “gcode not sliced for this machine” warning message on lcd screen

Getting a warning message on my MK3 with mmu2 . It says gcode not sliced for this machine. I can press continue and it will print.

i am using the Prusia slicer 2.1 1 and the profile is for an mk3 mmu2 . Any ideas out there ?

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

Hi William, 

do you have the latest firmware and prusa slicer versions loaded? 

 

Prusa have recently started adding Gcode messages to the sliced Gcode, to try and help us prevent various own goal errors...    they look like this 

M862.3 P "MK3SMMU2S" ; printer model check    
M862.1 P0.6 ; nozzle diameter check
M115 U3.8.0 ; tell printer latest fw version

the first line checks against the loaded firmware version... 

the second line checks against the expected nozzle diameter in the printer firmware configuration, this code snippet is expecting a 0.6mm nozzle, so if you have the standard 0.4mm zozzle fitted and recorded in the printer config, you will get a notification,

the third line checks the loaded firmware version against the slicer's expected latest firmware...

regards Joan

@joantabb

Thank you for the info. 
it has started when I did the Prusia slicer upgrade. In the config I only choose the .4 nozzle. Will go in an check out the gcode 

thanks

I'm also getting it when I use the MMU2 Single Mode as a Printer profile.

I see in my GCODE Printer Settings:

M862.3 P "[printer_model]" ; printer model check
M862.1 P[nozzle_diameter] ; nozzle diameter check
M115 U3.9.0 ; tell printer latest fw version

So I assume these variables get their value from something within the Prusa Printer itself and not from PrusaSlicer, is that correct or is it the other way around (those variables get their value from something within PrusaSlicer)?

 

Thanks

Ed

Hello - does anyone have any answers to fixing this? - I have the latest slicer and firmware - import my stl. save my gcode and print and get this message

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

These are safety checks triggered by 2 factors:

Under Printer Settings->Custom G-code-Start G-code, you'll see the following lines:

M862.3 P "[printer_model]" ; printer model check
M862.1 P[nozzle_diameter] ; nozzle diameter check
M115 U3.9.0 ; tell printer latest fw version

These embed the printer model, nozzle and target firmware information used to slice the gcode into the output file. If you remove or comment out (precede with semicolon ';') these lines in the startup gcode, you can save a custom printer profile that does not include these checks in generated gcode.

Alternately, you can disable the checks on the printer itself. If you open the printer menu and navigate to Settings->HW Setup->Checks, you can modify or disable warnings for nozzle, printer model and firmware.

I'm the only user of my printer, so I find these hand-holding checks annoying and just disable them on my printer.

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

I just figured out the fix.

The custom G code

M862.3 P "[printer_model]" ; printer model check

results in 

M862.3 P "MK3SMMU2S" ; printer model check    

in my gcode

removing the P so it becomes

M862.3 "[printer_model]" ; printer model check

does the check properly.

I'm having the same issue.  I found this in the Prusa Knowledge Base:

M862 - Print checking M862: Print checking

Checks the parameters of the printer and gcode and performs compatibility check

  • M862.1 { P<nozzle_diameter> | Q } 0.25/0.40/0.60
  • M862.2 { P<model_code> | Q }
  • M862.3 { P"<model_name>" | Q }
  • M862.4 { P<fw_version> | Q }
  • M862.5 { P<gcode_level> | Q }

When run with P<> argument, the check is performed against the input value. When run with Q argument, the current value is shown.

M862.3 accepts text identifiers of printer types too. The syntax of M862.3 is (note the quotes around the type):

M862.3 P "MK3S"

Accepted printer type identifiers and their numeric counterparts:

  • MK1 (100)
  • MK2 (200)
  • MK2MM (201)
  • MK2S (202)
  • MK2SMM (203)
  • MK2.5 (250)
  • MK2.5MMU2 (20250)
  • MK2.5S (252)
  • MK2.5SMMU2S (20252)
  • MK3 (300)
  • MK3MMU2 (20300)
  • MK3S (302)
  • MK3SMMU2S (20302)

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

May well be a different problem, but I was getting this error message when using octoprint to automatically turn on the printer using tplink plugs in response to the Prusa slicer gcode upload.  Octoprint was kicking off the print before the Mk3s had detected the mmu2 - so was reporting the wrong printer type.

I work around it by either introducing a delay gcode at the start or moving the model check down until after the nozzle heating - this then gives the printer time to have recognised the mmu2.

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

I slice most things for MM2S single mode, and I normally have the MMU2S power disconnected, and it does not complain.

I commented out the firmware version check, however, as I will probably continue using the version I have until there is a specific reason to upgrade.

If I re-print my older .gcode files that were sliced prior to the MMU2S upgrade, it will complain, but I tell it to go ahead and it will print fine.

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

It says when you use the [P] argument “The check is performed against the input value.”

Does that mean the G code output file is compared to something that is stored on the printer, and if the two text strings don’t match it throws up the error for a wrong printer?   I’m just trying to find the two things that it’s comparing.   It would just be nice to squash this bug and make those two text strings match.

RE: Getting “gcode not sliced for this machine” warning message on lcd screen

In addition to the other ideas out there, for me, I had mistakenly flashed my mk3s+ with the mk3 firmware.  Once I corrected the firmware the errors went aways.
