I have a clearance height issue in my workshed due to a loft. I had to modify the cable arm tower to fit under. At first I cut the tube near the beam and used an inserted spring. The weight of the cables plus the movement of the axis’s pulled the cable down too low, I was afraid that it would get in the way of the work. What I ended up doing was adding some PVC sections, cutting the tower pipe into a few sections and adding some gantry carabiners and wire wrap. It works really well, allows for full travel and keeps the wires neat and out of the way. If anyone is interested I can share how I did this.
