OK, another few questions regarding this mill.

1. If I were to convert this mill from brand-new, would it be possible to use the factory motion screws and put Nema 32-960's into them, and build the controller WITHOUT switching to ballscrews? I'd like to do the project in 2 or 3 phases ($$$!!) if I could. I'd add ballscrews in phase 2.

2. I'd like to use Gecko 204V's and a PICStep opto-breakout board for my controller. Do they play nicely together?

3. Other than the Gecko's, breakout board, power supply, and on-off switches, what else should go in the controller box?

Thanks

I think you mean N34 motors and G203V Geckos. N23 motors of 387-500 oz should be more than enough for X/Y. N34 640 - 960 oz should be ok for Z.

You will want to wire them in Bipolar Parallel and match the motor best voltage with the PSU. Formula for best/max motor voltage is 32 times the square root of the inductance in mH.

203Vs are the best IMO.

Actually, 203V' and N34 are exactly what I meant. Good Catch. (Damn salami fingers!!!!) Are 960's overkill?

Also, do I NEED ballscrews or can they wait till later?

Yes, 960s are probably overkill. Bigger motors run more slowly than smalller motors.

You will need to be creative, but lots of CNC conversions use stock lead screws. The downside to that is that because they have more TPI, the rapid speed is lower. The upside to that is that because they have more TPI, the accuracy is higher.

CR.

Hello

I have an CT129 and want to CNC it!

If you are in the process of buying parts maybe I could order the same parts and combine out experience

Same thing for me here I would like to step through it in stages and build it as i go

Any comments would be appreciated

Thanks

I'm In, I'm looking @ Rockcliff machine for the control board > http://www.rockcliffmachine.com/electronics.htm

I'm also in the process of disassembling CT129 and seeing what I've got to work with + I need to clean.
