After kitting out my CR-10S with stepper motor dampers, I found the Y-axis stepper motor listed considerably - some 10-15 degrees due to the belt tension.
This bracket idea from Scholle was perfect and as you can see from the photos, the motor is perfectly aligned (I wish I'd taken a before photo now!!)
Due to the angle, I didn't take any chances and I took to fusion to really beef up the bracket to make it stiffer (I didn't have the belt too tight)
Really happy with this mod.
I printed the part in the same orientation as it is on the machine.
You will require the following:
2 off M3 x 40mm screws to replace the original stepper motor screws (thickness of damper means the original screws are too short).
2 off M3 x 8mm screws to screw the damper to the bracket
2 off M4 x 8mm screws and 2 M4 tee nuts to secure the bracket to the frame extrusion.
