It looks like NI will be able to loan me a sbRIO to control the system. The form factor doesn’t fit into my design quite as well, but internally it is identical to a cRIO. I really can’t complain if they loan it to me for free…
Bearing kit arrived today. I put it all together but the slide units have a lot more friction than I expected. After looking closely at them, I realized there is a rubber seal on each end of the bearing that rubs against the shaft. I decided that for my use case I don’t need the seals. I tried to remove the seals, when I discovered the seal has a metal washer inside it for strength. I ended up just scraping off the sealing edge with a razor knife. The slide unit moves much, much easier now. If removing the seal was a bad idea, I always have a spare slide unit that still has the seals intact.
Motor arrived today. It looks pretty good. The only problem I see is that the motor wiring kit came with a one foot cable, and I need about 4 feet. I will have to find a new cable somewhere.
