The motors you are using are relatively high Inductance so will require more voltage to spin fast but still with 100mm pitch they should easily reach 500rpm if wired Bi-polar parallel.
If series wired then this could be your issue because torque drops away quickly as RPM increases and with only 36V may struggle to spin much more than 500rpm.

Do the Motors have 4 wires or 8 wires.?
hi jazz 8 wires wired parallel, the only settings that can be set in controller is calibrate the distance moved, table size, homing switches
I cut square 100mmx100mm and put that in till it gets to right um pulse, which works out at x 15.621760 and y 15.575712

thanks jazz kev
