I recently bought the k8200 and assembled it. Since it didn’t really seem to work for me to measure the voltages on the motor drivers, I went ahead and launched repetier to test if I could manually control the X,Y and Z movement.
X and Y worked fine, Z got the signal to move but it seemed like it didn’t had enough strenght to rotate the Z-axis around. Since I had allready ordered the k8204 upgrade I decided to wait untill it arrived and try again when I mounted the Z-axis upgrade. Just an hour ago I installed the upgrade but still the Z motor seems ‘to weak’ to get it going.
I grabbed my multimeter again and tried to measure the voltages again. When i’m measuring these the first number that pops up is around .350, but it immediatly drops down to .008 - .0015
Am i measuring on the wrong spot? has this anything to do with the motor? I have no clue since the X and Y motor drivers give me the same measurments and they seem to work fine.
It turns out i was using my multimeter the wrong way. I now have succesfully adjusted the voltages on the extruder motor driver and the X axis. The Y axis gives .780 and doesn’t change, the Z axis doesn’t seem to give any voltage (.000). Could it be that this is because of a faulty PCB?

Best way to check if your driver is bad is to swap it with another one. If your Z axis is functional ant the other not you have a stepper driver issue.
Before using the printer, you should set the reference voltage of the stepper drivers around .5V A higher value is way too much and .38 way too low.

So I can just swap 2 of the stepper drivers (a working with a non working) to double check if that’s what’s the problem ?
Exactly. If the problem shifts to another axis and your Z axis is working then the stepper driver is to blame.
But don’t forget to adjust the drivers before doing any test because at 0.38V the motor probably wont move.
