Just finished building my K8200. Everything went according the the instructions except for adjusting the motor voltage. My voltages are E-.83, Z-.78, Y-.74, X-.79 and none of them will let me adjust the voltage down to the .425 to .55.
The first time I did this I had the same problem.
After many attempts I had to get a magnifying glass and to see what was going on.
Turns out the screw driver I was using was to big.
0.55 works best.
Ok. Thanks for the advice. Best I could tell it looked like they were turning but I’ll get a magnifying glass and try again.
Thanks for the tip. Even with the magnifying glass it was almost impossible to see if the screws were moving. I had to take a small jewelers screwdriver and file the tip down, but was able to get them adjusted to .55v each.
Glad to hear everything worked out.
I should warn you.
