If the shaft size is OK for you, then yes, tinyG will make it move.
tinyG is limited to 2.8A per winding output, so may not develop full spec torque.
Yes, I had so I apologize for the repeat question and I appreciate you sending me info on your choice of motor and indulging me. I see quite a difference between the two with regard to Current/ph, yours being 1.8A and mine at 4.2A so I have a choice in my opinion to either return these for the lower amp'd ones or, in order to get full benefit, move away from the use of a Tiny G. Does that make rational sense?
Honestly, I have no idea what would have been a best choice but since we last spoke I have completely built a new and more robust CNC complete with a steel gantry, slide rails, and ball screws so I just thought a little more meat on the motor shouldn't hurt. Sounds like I may have pushed myself away from the use of the Tiny G or at least to it's limits.
I am open for your advice. If it to return those for lesser sized ones or keep what I have and move to a breakout board, separate motor power modules, and Universal G Code I'm all ears.
By the way, I am fine with the 10mm shafts. In fact I purchased 10mm ball screws and 10mm x 10mm couplers as well.
Thank you!
