Z Step
Is it required to calibrate the motor steps? My Vcore 3.1 500 seems to lose height on tall prints and eventually knocks the printed parts and so think the Z Steps might be an issue.... Or maybe not.....
This happens so much so that it breaks the "Tree supports" but snapping them in the middle. Bed adhesion is amazing.... but the force of the nozzle hitting the printed parts while traveling to next section is not good at all

Z Hop is currently at 0.4mm

Have you checked your Skew? I don't remember doing anything as part of commissioning regarding steps. If the skew is out though would that lead to an impact over time?
Will double check. Thanks
There was a similar Problem here recently. Motor steps are hardware dependent from you Pulleys belts etc. so no calibration needed.
If you loose Z height over time check your grub screws on the z-motors, if they're loose a slow deviation in Z or one of the z-axis can happen
Just cannot figure it out.... Print head seems to not be moving up enough. Should not see these drag marks with Zhop on or off.
I have checked this again, they are tight
While I could update rotation steps on Z motors. I would not thinks that 0.49mm over a 200mm distance should affect the prints on a 4 layer print (as seen in pressure advance test above)
uff sry then I am also not sure what the issue is....
I wouldn't update the rotation steps on your z-motors, the 0.25% deviation you measured are probably in your measurement error.
what you could try, is printing a large square in vase mode, if you loose z steps on one motor you should see that side being squished a lot more
