Hi, I am designing a fixed gantry fairly small desktop machine (inspired by the eco one cnc ) about 300x300mm working areas, total size perhaps 400x500

I plan to mill 10-20mm aluminium pots and am looking to use good linear guides hewing and ball screw drives etc.

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!!
