Print without Input Shaper on MK3.9?


as there is no profile without Input Shaping for the MK3.9 upgrade - is there still a way to print without it?

I am not really a big fan of the Input Shaper for functional parts, neither on my MK4 nor on my MK3.9 - the results are still better than my upgraded Ender 3 V2 though - but not as good as with the 0.2 quality settings. Maybe going back using gyroid will help a bit as suggested in an MK4 thread - but a non Inpus Shaper Profile would still be nice to have.

There is still a certain weirdness to it - maybe the frequencies are off on my concrete paving slab on composite foam combo the printers are placed on?

If you make this entry in the start gcode of the printer, input shaper is disabled.

M593 X T2 F0 ; disable IS

M593 Y T2 F0 ; disable IS

Topic starter answered:

Err... That is most certainly correct - but not really what I wanted to achive 😉 InputShaping may be disabled then - but that would propably even worsen the quality as the printer still prints at high speed - but now without the compensation of InputShaper...

Maybe I should re-phrase the question to "quality profile for MK 3.9"?

I've been fighting with passing the axis tests on firmware 5.1.0. The Y axis passed just fine before, but the fan didn't. So support had me upgrade to 5.1.0... now the Fan passes, but the Y fails... I think because the Y fails, it stops further tests and tuning.

I was asked to try some prints and so far they sucked! The X axis is shifted with every layer.

I finally tried slicing with Mk4 no Input Shaper as @Sandre4 indicated.

So far my benchy is "better"... There is the ocassional X shift, but nothing as bad as with input shaper.

Yep on my MK3.9 Printing without InputShaper is done by using default MK4 profile. An interesting note: Input shaper limits layer height, there is no 0.07, or 0.05mm ULTRADETAIL and no 0.30mm DRAFT mode.

Kind of a shame it's not more clearly noted...
