Uhg. Doing the best I can here but...
The couplers are what came with the kit. I have maybe the second batch of Hadrons.
The motors are larger than the feet, so to keep them suspended and balance the machine on the actual feet I've got it sitting on a piece of ply that doesn't go under the motors.
The motor mount pieces flex, eve with no weight on them. So lining the z rods up with them is difficult as the motors tilt. They stop tilting when they get attached to the z rods.
However, after trying to recalibrate here one of the motors has decided to have it's entire mount move back and forth when the z axis is moved. It didn't do that before, before both motor mounts simply flexed when in use.And no I can't tighten the plate anymore, the screws can't go down further. You can get it to play easily by hand as well though. Not sure what's going on here.
And hanging the z rods, well there they don't hang straight. They have a significant amount of play while hanging, so it's difficult to get them centered over the motors without holding them to maintain square with the z maker slide.
Gonna play at this a little more before throwing in the towel for the evening.
