33 Oz/in Motors Are They Enough

[chadwiggan]

I RECENTLY FINISH A CNC ENGRAVER AND CHOSE HOBBY CNCS 33 OZ/IN MOTORS TO RUN IT. I WAS JUST WONDERING IF ANYONE HAS USED A SIMILAR SIZE MOTOR AND IF YOU HAD ANY TROUBLE WITH THEM. I REALLY DONT WANT TO GO THROUGH THE TROUBLE OF MOUNTING THEM IF I HAVE TO STEP UP TO A NEMA 23

33 Oz/In Is not very much, you might be able to get away with it but I will suggest getting some cheap (ebay) 100 oz/in, thus give you 3x the odds that have have strong enough steepers to not skip steps...

thanx cromwell

ill look into those motors on ebay. do you know if ill have to switch from a 12v 8a power supply to a larger one to run that size motor

[balsaman]

The 8 a powersupply will run almost all 50-100 oz motors, especially if you are running a chopper controller. If unipolar, you can run motors up to a little over 1.25 A. per phase.

BUT, PC powersupplies work and are cheap. Use one for the Z and one for X and Y.

thats a good idea eric im using a modified pc power supply right now so all i have to do is modify another and hook it up to just the z?
