Dear Forum.

I'm getting warm on the idea on getting a 4.th Axis for my diy machine.
Primarily wood routing.

I found this kit on eBay:
http://www.ebay.co.uk/itm/CNC-Router...:X:RTQ:GB:1123

However the motor fitted is a 2-phase stepper NEMA23.

My machine is build up using 3-phase steppers NEMA23, and I already have the drive and motor in spare.
So I wanted to replace the motor on the harmonic drive.
Don't know much about alignment and harmonic drives, but from the picture "it seems" fairly easy.
Is there any alignment/adjustment involved in this, just so I don't start out breaking the wave generator or flexible gear.?

1. Alternative could be getting a 2-phase driver, but that adds to price, as I already have motor and driver.
2. Alternative Getting a belt driven instead, but I like the high torque from this, If one day I would expand with a 5.axis.

Best Regards, Bo Andersen.
