I am getting the impression that servo drives may not be that necessary so am looking for micro stepped nema23 with 3Nm torque. Can anybody recommend good drivers/ stepper motor suppliers, also a controller that has USB and some support. It seems so much electronics here is from china with poor support/ documentation.

I am quite tempted by the planetCNC controller and software as seems that its quite regarded and can work with several platforms including osX. Bit of a mine field out there it seems. Im pending good money on all the mechanics so don't want to skimp on poor quality electrics

Any help would really appreciate it!!

Also had good motors/drivers from longs motor and wantai on ebay (chinese)
Don't bother with Zapp automation.

Recommend use at least 48v power supply with Nema23 motors.
