I have 3 of the STMBL drives and a couple of spare part drivers. One STMBL on the spindle and I was thinking replacing the HP_UHUs for the two brushed DC Servos. However, couldn't get rid of the whine so went back to the HP_UHU. But then I've also got 2 extra HP_UHU drives that are partially assembled. And now a two US Digital encoders that were replaced with CUI that work better. And then there's the extra Shumatech DRO-350 kit still in the box and the two DRO-550 of which I only assembled one but haven't used yet.
Oh and the 400W Bergerda AC servo. Ran the X axis really nice but nowhere to mount the drive in the present cabinet. Oh the list goes on....
