POwer supply is 36 volts, the drivers are DM542, the Motors are rated at 4.2 amps. I am almost sure I set them at halve current setting. I will open up the case and have a look.
Sounds like a Longs or Wantai drive kit.
Had the same characteristics on my old X2. All still works.
I put it down to the highish inductance of the cheapish motors.
It's not like you can set the driver current too high for them and burn them out!.
