Torque is made by Amps, and Speed needs Volts. Do you loose steps at very low RPM or at medium RPM? If at low RPM, only increasing the current will help.
With a piker torque drops rather quickly at higher RPM's so if you are loosing steps during rapids or fast cuts, increasing the voltage would help a little bit. Changing to Xylotex or Gecko helps a lot.
