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.
