I saw limit for stepper is Vref = 0.6.
I had to push them to 0.7 to stop loosing steps. It is now ok.

What about extrusion motors ?
because of the difficukty to push pla in diamond hotend, they often loose steps, even at 0.7. Where can i go ?
O,8 is possible ?
Thank you for your help.

I guess 0.8V is OK,mine is .9 and it works fine.(Though the value is different from calculation.)
