M92 command  

M92 command

Hi !

Did anyone try, with success, to correct X/Y/Z dimensional accuracy using M92 command ?

I use it, with the start g code, to set up my mk3s+ with a very great success (imagine Borat, here).
I can achieve 0.03mm accuracy, which is amazing.

But I can't figure out how to manage it with my mk4 : at first, it messed up the homing. So I moved it further in the start g code. And it does not affect the dimension as I want, as it does on my mk3s+.
If I try to modify it with a larger scale, as 1/2 on X or Y axis, it works : my 20mm part is 10mm on X or Y. But it does not work for minor adjustments.
Did I miss something ? As Y is nearly perfect, I start to think that this printer is made for accuracy, just OOB. And the X axis belt is just not correctly tighten.

But I would prefer the M92 way, which is more convenient and provides (on my MK3S+ only....) excellent results.

Thanks !
