reprap stepper control arduino system does it work for 3 axis cnc?

reprap stepper motor control system & arduino system does it work to control the 3 axis cnc machine they sell parts for at the RRRC?

Yes the stepper drivers and the Arduino system are exactly what is needed for a CNC.

Reprap is a kind of CNC machine that deposits material in stead of removing material.

The MCwire design or any of the small CNC designs on Instructables.com could be driven by the RRRF electronics. The steper motors from the RRRF would be ideal or need to be of a similar spec to the motors specified. The stepper drivers can only contoll steppers that use up to 2A per winding with a voltage less that 12v .

This is why the electronics are only sutible for a relativly small CNC machine.

It should be possible to use more than 12V, but that would improve speed rather than torque.

Yes you can use up to 46V with the 298 devices V1.2 and V1.3 stepper boards.

The components supplied in the kits could be a limiting factor.

The cct was based on a 5v & 12V supply from an Old PC switch mode PSU, using the 4 pin molex D connectors as used in HDs & CD drives.

So you may need to adjust the values of R8~R10 to suit the voltage of Vss

You must check that the maximum voltage of C2 is adequate for the new supply voltage. An electrolitic capacitor given a higher voltage than its rateing is very dangerous.

I've been using the V1.2 stepper drivers and a Sanguino to drive my Sherline mill. Has been working like a charm so far. I use custom firmware on the Sanguino.
