    I have a similar spindle on my 6040, and at full noise (24,000 RPM) running a router bit fairly hard, I've never seen the current displayed on the drive get above about 3 Amps.

    The stepper stalling if you try to accelerate it too fast is normal - typically, if you increase the motor voltage you'll find you can accelerate faster than at lower voltages.
