Those motors have very high inertia and high inductance, so they dont spin as fast as the 34's, also the PM2278 goes up to 220V, so you will need to get a transforma regardless because it is not advised to put 230V single phase straight in.

Another thought was i could even go for a single NEMA 42 for the X axis and drive both of the ballscrews with a belt coupled together! what are your thoughts on this guys? the NEMA42 is rated at 2830 oz-in and can work at a max of 210v do you think this would work. ( im just trying save money as funds are abit low at the moment )
