BTW. One of the reasons I'm trying to see a US or Canadian distributor is one or two units with FedEx shipping is expensive. They won't ship mail because so much gets lost. They are truly a manufacturer and not just a reseller.
So far each time I order one motor I add one or two more of something else. So now I have 3 of the 40 series AC servos and could outfit all three axis of a mill. I also have two stepper drivers, one for each of the size 34 steppers I have sitting on the shelf. The whiny stepperonline from amazon.ca has been sold at a discount to a friend who doesn't care about the noise. I've not updated the X and Y on the mill because at the moment the much larger brushed servos with HP_UHU drives are working fine. Still need to add ball screws and power draw bar so why muck with what works. Not sure yet what I'll do with the steppers. Maybe for the South Bend Heavy 10L.
