3 x 2.5Amp 30V Stepper Drivers

Yes,
Providing you are not trying for a low earth orbit then yes they will work satisfactory and give you what you are asking for, a cheap setup.

True, I might have been a bit quick to assume that he wanted to run the motors optimally. It would be cheap. I think it's the 3Nm motors... so they would have to be used in Bipolar-series which doesn't help matters.

I started off with 1nm motors and a unipolar stepper driver on my milling machine. It worked, but snails go faster than the 1mm/s it did.

Hi, I was using them to run some 23 frame 2Nm motors, easily did 600rpm which was more than enough for me.

With my 3mm ball screw I got feeds of 1800mm per min no trouble at 24v.

Cheers.
