After installing a new MKS Base motherboard some prints came out shifted...in particular the larger and more complex prints, and combined prints...very frustrating!

I remembered that I had this problem before and it had something to do with the stepper motor..not the slicing, not the memory card, not the power instability :-)

For future reverence I post this installing addition.

The voltage is measured between the USB casing and the stepper motor potentiometer.
I currently set the potentiometer voltage to 1.2volt i.s.o. the advised 0.9/1.0.

Before adjusting the motors were quite warm (indication for a too high current/voltage), about 41°C...
After adjusting they were about 26°C, some 10°C above room-temperature.

A too high voltage causes the stepper motor to overshoot the next step, and also may cause to shake the (larger/higher) print loose.
At a too low voltage the motor might not be able to overcome the sliding resistance or displace the printed mass.

Through some kind of blockage or overload your stepper may be (temporarily) o.o.o. (out of order).

I had some trouble with my extruder, so I switched from a one extruder setup to a two extruder setup.
Then I plugged the extruder into the second extruder connector but that didn't work.
Then I thought that my stepper was defective, so I tried it in the X and Y connector, which did not work as well. So...the stepper must be o.o.o. right?
It so happened that I had a new set of 5 steppers available, for a yet to build 3D printer (HyperCube). Tried them all, and all were failing.
Five new and defective steppers? Unlikely!

Long story short:
I switched all stepper motors and all X/Y/Z/E connectors live (with the power on).
This produces a surge current that blows out the stepper driver, destroying it beyond repair...
Just to be safe, I ordered 2 new controller boards, and will really remember never-ever to "hot-switch" my stepper connectors!!!

Otherwise, check your stepper motor voltage, maybe it's too low, or strangely too high.
Consult your supplier, or look it up; stepper motor tuning, or something like that.
