Re: NEMA 23 Z-axis Kit

Is there a drawing somewhere for the Nema 23 Z mounting plate?
I drew this up myself, but I'm not sure if I trust my own measurements :ugeek:

Re: Nema 17 motor for HobbyCNC?

Thanks. Looking around, I don't see any unipolar Nema 17 motors with torque over 42 oz/in. I do have a Nema 23 305oz motor to spare (I have 4 of those total), but I'm afraid that all 4 running together will be pulling too much current. Plus it's heavy as hell. I guess I can try it out and see if any...

Re: Nema 17 motor for HobbyCNC?

6 or 8 wire motors will work with the HobbyCNC Pro board, they just need to be unipolar. I'm having a look on eBay now. How does this one look...

Nema 17 motor for HobbyCNC?

I have some hefty Nema 23 motors (305oz/in) that came with a HobbyCNC kit that I am going to use for the X and double Y axis. I picked up a Nema 17 from Inventables to run the Z axis. I figured the motor from Inventables would use less amps, be lighter, and be plenty powerful enough for what the Z a...

Re: So you're thinking about scaling up.

My Shapeoko kit is still incomplete, but I've been thinking about how to eventually scale up. Ideally I'd like to be able to slide a full 4ft x 8ft sheet of material onto the bed - not necessarily be able to cut that entire area, but I'd like the gantry to be wide enough to get part of the sheet on ...

I just got the mechanical kit from Inventables and am planing on Nema23 motors. What is this problem with the current plates?

Re: Bosch PR20 Colt - Anyone try it?

I already have a Porter Cable 7310 trim router (5.6 Amp, 3/4-Horsepower, 30k rpm) but since it's single speed I'm hesitant to use it and the Bosch PR20 looks ideal.
Has anyone actually tried it out on a Shapeoko yet?
