I am going to check with the manufacture and make sure the data on the ball screws was not a typo. I find it hard to believe also.
My only concerns with the Xylotex were if I could get more than a 4th axis and it seemed weak. I bought a small bipolar motor to play with. When it arrived I was surprised to see how small it was. I can't test it untill I have a controler but it looks like it couldn't power much. It is rated at 2.8 amps bipolar series and 35 volts. Xylotex is rated at 2.5 amps and 35 volts. That made me nervous. I did not think Xylotex could drive a 250 oz/in motor. I guess I can't judge this motor by its looks. It is also rated at 1500 rpm. This motor by the way is a Pacific Scientific Powermax II M21NRXA-LSN-M1-02.
As far as more axis is concerned, I just need anouther parallel port and anouther board and appropriate software. I think I may get the Xylotex.
