It is rather distracting.

Those motors don't have much torque (1.5Nm) for nema 34. The datasheet only mentions A and B phases and 8 wires so looks like it's 2 phase. Standard 5-phase stepper motors are 0.72° step angle, whereas this one says 1.8° which is standard for 2-phase 200 step/rev. I've got a fairly big Nema 34 stepper motor lying around somewhere. You can get stepper drivers for them on eBay, but I just made a simple unipolar drive for it and it works. Never actually used it - one day I'll make a proper bipolar drive for it. It's a good candidate for my lathe I reckon...
