M900 is not supported

[SIam]

@mendelevium can you post the first 50 -100 lines of this g-code file which this error occur

[alankilian]

@siam If you export your factory file and post it here I can load it in Simplify3D and see if I can find where the M900 is getting added.

[Phaedrux]

Do you have Simplify set to reprap gcode flavor?

[SIam]

@alankilian I didn't use s3d since some months because i find the most other (free) Slicer are better than that... but this is another problem so please post your g-code

@mendelevium said in M900 is not supported:

M115 U3.1.0 ; tell printer latest fw version

This is invalid for RRF (no U parameter) and un-necessary.

M900 K30

I suspect (as @Phaedrux asked) you have the slicer set to something other than RRF flavour.
Or you have not altered your start G code in the slicer to suit RRF
M900 sets marlin linear advance.

[mendelevium]

@owend
its RepRap I have put a sreenshot.

[mendelevium]

@mendelevium
I believe the issue is in the startup scripts in my simplify 3D

Is there a substitute G code?

here is is.....

@mendelevium, M900 sets pressure advance in Marlin. For some reason they chose not to use the M572 code to control pressure advance, which we had introduced and allocated in the RepRap wiki several years previously.

It's not common to set pressure advance in the GCode file. You would normally set it in config.g or in the filament files. So I suggest you remove that M900 command from your slicer start code.
