I found out what they do, one is a direction reverser, the other makes it open loop. Suits me anyway. I'll get one of those supplies and one of these on the same table and play with a function generator tomorrow, claims to be good for 200 khz steps, and has divisors out the yang, so it ought to be a dropin except for the mounts and shaft sizes so I'll need to find some timing pulleys and belts. And a nema 23 mount since that 1600 oz/in on the Z now is a nema 34 mount. An see if there is room enough behind the apron for one of them, its 124mm long in which case I'll order another for the indexer and put both of these on the Sheldon. That 8 lead nema 24 on the x is slow, stalls at about 30 ipm. even when set as 4 wire parallel and all the amps a 2m542 can do. Even then it runs cooler than steppers usually do. The x belt tensioner is drilled for a 23 and then the holes were moved enough for the 24. > My guess about the cable length mismatch is that the seller you bought > this from gathers parts and packages them and this motor was made for > a use case that did not include this controller. The motor and encoder look to be an integrated unit. So I'll have to splice it, or pull the cover and see if its easily replaceable with a smallish 18 or 20 gauge line cable. Lots of layup stuffing on this one to get to a matching cable jacket size, the wire gauge itself isn't impressive at all. At its peak of 4 amps a coil, that cable WILL heat. Not badly, but detectable. > > When googling for the instruction, look for related controllers as I'd > bet the firmware was written to run on many different sizes of > controllers, not just the one you have.
