As I said, looking very good indeed!
I expect you are well aware of this, but, just in case, you should set the current limit for the stepper motor on the driver.
A link showing this is here, about 3/4 down the page.
Have fun

Thanks Philip, yes I have been using the DRV8825 drives for a while on my DIY engraver, with the same CNC shield. With the small NEMA17 motors I set the current limit just a bit above 1A.

Josh, this CNC shield is open source, and it is used for all sorts of DIY engravers and 3D printers. The firmware for CNC control is available from the GRBL website. I am writing my own firmware for the telescope control.
