microcosmo has generated a nearly perfect cable guide for the A1. There is no force on the cable in any direction, unfortunately, when you use the complete height, the toolhead is crashing into the guide where the cable is held.
I have chosen to remix this in fusion 360 and move the cable guide holding area 4 mm to the back. This should solve the most problems.
However, you should not mount the guide/holder to the far right end near the portal post as it would interfere with the Z axis guide when moved to the top. Please check the photos for the location where I do not have a problem.
