What means 189nm? nm is the symbol for nanometre. You wanted to say Nm? Then I doubt there are 189...
What steps have you set to 3200? Are you talking about microstepping? Are you setting them in a drive unit? Has this drive unit a name/model number?
Your 800 mm/sec does not look fast... What software are you using? have you set the unit correctly? What is your acceleration?

You are asking about changing the motor but you did not tell us what drives you have (current and voltage ratings) and what is your supply voltage. Stepper torque at high rpm highly depends on the voltage and drive quality.
Thanks for reply, sorry about 2 threads was not sure if first was sent,

Motor 2amp series 4amp parallel 1.89Nm holding torque,
Driver. M542t. 24 to 50vdc 1.5amp to 4.5amp
Awc608 control with laser cad software
36 Volt switching power supply running drivers,
24 Volt switching power supply running Awc608
3200 is micro stepping

First this software as calibration like mach3, cut square 100mmx100mm till your steps are right,
Cuts ok 4mm ply as 10mms is needed, but engraving uses faster speeds, and I notice 20 minute job is about 50 minutes

Thanks again for reply kev
