Stepcraft cablechain modification

thingiverse

I noticed a Z-stepper wire was broken at the connection point near the left-Y bracket. I decided to rewire everything, replacing it with a cablechain instead. I reused an old cablechain (similar to the one found here: https://www.banggood.com/10-x-15mm-Plastic-Cable-Drag-Chain-Wire-Carrier-Length-1000mm-With-End-Connectors-For-CNC-p-995512.html?rmmds=search&cur_warehouse=CN) for this task. The cablechain is supported by an Alu 20x20 L-profile, which is held in place by two printed supports, the front and back support items. These supports are secured using one M3 screw each and fit tightly. I used a 12-wire Lapp-cable with 0.5mm (numbered) wires for this project. The first four wires are connected to the X-stepper, while the next four are linked to the Z-stepper. Wires nine and ten control the endstop switches for X and Z, respectively. Finally, wires eleven and twelve power the LED-strip. The cable itself comes from Conrad (https://www.conrad.be/p/lappkabel-0026105-geleiderkettingkabel-olflex-fd-classic-810-12-g-050-mm-grijs-per-meter-602996). I reused a cable protection sleeve, originally used for the cabling under the bed to the controller board (13mm dia), and installed it on the X-axis. The locking x-rail and x-rail parts fit snugly into the top slot of the X-axis. The cable cover part clicks onto the Y-support bracket, effectively covering the cable connections.
