I have several Qidi's and a Flashforge (all running sailfish 7.x), and none of those get hot steppers during printing.

Can you find any serial number/product number on the steppers and look up the advised currents?
So, I found that the VREF pot. settings for my printer were as follwing:
X: 118
Y: 118
Z: 40
A: 118
B: 118

The stepper motors on my printer are all the following model number: 42HB34F08AB 06. (I found a specifications sheet here: http://voltom.ru/info/42HB34F08AB-06.pdf )

The advised current says 0.8 A/Phase, but I don't know what the VREF settings mean in practice (and I'd prefer not to have to grab a voltmeter and measure manually).

According to the link below, to have an output of 0.8 A, I should change the VREF to 85.
