You still miss understand
the calculation is for max torque, most printers don't need to run at max torque and thus can run fine with lower vrefs. (and much lower noise levels)
when printers suddenly start layer shifting they normally need lubrication, not re adjusting the vref to force the printer to overcome the additional friction.
No, I did not misunderstand, Without knowing what Max Torque you have no ideal the max V-Ref you are allowed and adjusting past this point can be disastrous.
I am not running Max Torque my calculations .9 * 8 *.1 = V-Ref .720 I have been running .400 this value is too low and causes stepper motors to skip steps.
In turn it directly causes the layer shifting that the 3D Printer has been experiencing.
Took the calculations off my other 3D Printer where I was given factory settings for the V-Ref of 0.800 calculated the percentage from Max Torque to get 67%.
Actually I have been running the 2nd 3D Printer at .700 which is ~60% of the Max Torque calculated V-Ref setting. When I lower the V-Ref I get the same Layer Shifting.
Took this calculation into perspective for calculating an average for the 2nd 3D Printer By the Same Company came up with ~60% Adjusted V-Ref to .500
Only increased the V-Ref voltage up by 5%
Lowering V-Ref on the 2nd 3D Printer resulted in this Print.
Left Image is a similar Model, Right Image Incorrect V-Ref is Layer Shifted.
