Hood, you took out the motors and drives and put in new ones, was that because the old ones were dead or did you just want new ones, or was it getting too hard?
The drives and motors were like new, I reckon the lathe had done under 50Hrs total. It came out of a University in Hull, UK and had been used for testing the differences between CBN and Ceramic insert life. I found a paper on the net that detailed the tests and the results, was quite interesting
There were two reasons I didnt use them. First was that my friend bought the drives and I bought the rest of the lathe, he has older CNC's that use HiAk drives so he wanted them as spares and the second reason was that when I did this there werent any devices like the DSPMC about so no way to convert the Step/Dir of Mach to analogue for the drives. There were the pixie boards but they were seemingly a bit hit or miss whether they would work and also supply was patchy.
