Re: [CAD_CAM_EDM_DRO] small 3-axis micro stepper

Jared,

First determine what stepper motors you are going to use with them. The
xylotex board is limited to 35 volts.

As a general rule, if you divide the 35 volts by 20 you would get 1.75 volts
as the voltage for the stepper motors.

You can ask others, but I think that 2.5 amps may not be enough.

You may want to save up your money and buy Gecko drives.

Before I go out on a limb and buy one, does anyone see anything wrong with
this system for a small cnc? I have an Enco mill/drill table that is
slightly larger and heavier than a Taig's. I don't know what to use as a
spindle yet (I guess just a router for now). Is 2.5 amps bipolar enough? I
would greatly appreciate any help from those more experienced than me
(probably 99% of those reading this right now). My problem is that I can't
afford geckos, and don't want to buy a unipolar driver board and be
disappointed with the performance.
