Hi Charles,

Thanks for the Ah-ha review. I am hearing good things about their kits.

What you say about building my own the first time makes sense. I don't want
to screw around with the set up forever.

You say you have 650 oz-in motors. The Ah-ha sales guy, Mike, told me that
the highest they can go with the RC-500 driver/power supply box is the 450
oz-in motors they sell. This is because the power supply can supply only up
to 6 Amps/phase and their motors draw about 5.6 Amps. However, I have seen
stepper motors with torque much higher than 450 oz-in with current draw of
less than 6 Amps.

Do you have the RC-500 box or the bigger one from Ah-ha?

Did you purchase your motors from Ah-ha?

What brand motors and what are the specs (model #, amps/phase,...)?

What type of milling machine do you have?

What type of couplers did you use to mount the motors? (Mike suggested
helical couplers but I don't know what these are.)

What limit switches do you use and how repeatable is your homing accuracy?

Have you used the Ah-ha system for contouring? If so how well did it
perform?

I really do appreciate your help.

Thank you,
Peter
