Robo3D R1 Heatbed cable upgrade

thingiverse

I'm a proud Robo3D R1 user, and after printing over 200 jobs with my machine running smoothly, I encountered an issue - my bed temperature readout suddenly started showing 0 degrees Celsius. Investigating further, I realized that the culprit was a flimsy, stiff grey cable provided by Robo3D, which wasn't designed to withstand constant bending. To make matters worse, the cable was directly glued to the glass bed using silicone. I decided to remove both the cable and the glue to give my printer the upgrade it deserved. Since I rely heavily on my Robo3D for postproduction work, I couldn't afford to wait for a decent cable guide. Luckily, I had some spare parts lying around that I could use to create a temporary fix. My first stop was the Y idler block, secured with a single M4 screw. I noticed that there was an unused idler hole on the other side, which presented an ideal opportunity to install a cable guide. To make things more secure, I added a cable mesh clamp, fixed onto the stepper plate using a small bracket. To free up some space for the cable mesh, I moved the Y endstop and routed the cables accordingly. For my bed wires, I opted for silicone wire from the RC scene, which is designed to flex and bend easily. If you're interested in replicating this modification, here's what you'll need: * Printed parts (preferably ABS) * Cable mesh with a diameter of 6-7mm * A connector to link the bed wires (heater and thermistor) - Multiplex connectors are suitable options that can handle up to 35 amps continuous. * 14 awg silicone wire (available from HobbyKing or similar suppliers) * 22 awg like wire for connecting the thermistor You can watch a video walkthrough of this modification here: https://www.youtube.com/watch?v=HVe5srJrDmo
