I never understood the significance of closed looped steppers at that price point. Plus i pointed already a couple of times in forums where cheapest servos could be bought.

400w AC servo motor could be bought for ~180$ together with drive. JMC motion. 60ASM400 +MCAC808 , not sure of actual prices so have to check. Also they sold the closed loop stepper 3nm motor and 2HSS86H driver for around 130$ . that prices were when you buy 4x. Obviously a PSU must be fashioned. That includes cables so price was great.

So forget about the Leadshine for the moment, there are other players. That was an year ago. Now may be even sth else new on horizon.
