hello, Yes I did finsh wiring up and they run great. I am using a direct drive on 8tpi acme lead screw with delrin nuts. my current lead screw set up has a lot of friction and so even by hand the screws are tight to turn but even so the motors run them well. I can cut at about 120 ipm right now and I think I should be able to cut around 150 with ball screws The rapids are limited to the rpm of the motors which are around 1100 rpm so direct drive works the best. You can get a really good power supply here..

It will rectify up to 75 vdc~
and finally just so you have an idea of what they can push my machine is made entirely of steel the y axis weights aproxamately 150 maybe more.
I put my own encoders from us digital I used the E2 250cpr encoder with the screw down wing style they worked wonderfully because the motors already come with the screw holes for that type and size. The guy on ebay sells agilent encoders with the motors but I think you have to have a seperate power supply for those because the geckos are limited to a 5 volt encoder power signal. One very good reason to just get the motors and put the US digital encoders on them. One more thing dont pay his asking price if you just want the motors. I offered him 100 per motor outside of ebay and he settled for 110. maybe he might do that again.
