2012/7/6 BRIAN GLACKIN glackin.br...@gmail.com: I am a bit baffled. Why would you add milling capacity to a plasma table (other than to say you can do it)? Because it is so much cheaper than 2 separate machines! And yes, it will help my marketing, if I will have such a combo machine. My

2012/7/6 Ralph Stirling ralph.stirl...@wallawalla.edu: I'm looking forward to answers to those questions myself :-). Theoretically the AS5311 encoders have 2um resolution. I am going to be doing some repeatability testing tomorrow with an LVDT to try to verify the encoder performance. Force

I suspect it will, but I haven't seen anyone mention it. I propose to use it with a servo system, so I would think any latency coming from PCIe would have minimal effect, is that right? Eric -- Live Security Virtual

Brilliantly simple - why didn't I think of that :-). My motor generates 34N force for 45W power dissipation, for a motor constant Km of 5.0. My FEMM simulation indicated I should have had a Km of 7.7 or 52N of force for the same power, so I'm a bit low. I need to see if my magnets actually have
