I received a MKS GEN 1.4 and TMC2130 steppers for it and still have issues I am trying to resolve.
Ordered both at FYSETC, plugged in - nothing worked. Every now and then “Driver error” crashes (especially when I went near the SD card), but otherwise - nothing.
Replaced the FYSETC drivers by Watterott ones - no change.
I tried with and without SPI connected - no stepper motor moves when I connect it through a TMC2130. Unfortunately, no way to plug new steppers into the old board or vice versa (old board is MKS Base 1.4 with onboard drivers).
I heard that TMC2130s are most happy at 28V - my printer runs 24V, so should be pretty comfortable for them.
I was able to get rid of “driver errors” by disabling “Monitor driver status”, so basically disabling sensorless homing.
Now with SM being 2nd priority, my focus was to get the damn thing running.
No matter what I tried - FYSETC drivers, Watterott drivers, with or without SPI - I was not able to get any stepper to do a single step, so I got out my multimeter and tried to measure the voltage - and got a huge surprise, since all of the pins of every motor were powered with 24.4V.
Any idea what is going on there?
Thanks in advance
