I'm using the Robo3D R1 a couple of months now, and made 200+ prints so far working fine, until the bed temperature readout started to fail and showed 0 degrees. While investigating this, I noticed Robo3D used a very crappy stiff grey cable, Totally not designed for bending all the time.. Also the cable was directly glued with silicone to the Glass bed. I removed the cable and silicone. Since I use the printer 100% of the time for postproduction I could not wait for a decent cableguide. So I had to fix it with the parts I had laying around at that moment. First thing my eye fel on was the Y Idler block. Secured with 1 M4 screw. I decided to use the unused idler hole on the other side to fix a cable guide, and make a cable mesh clamp secured on the stepper plate. I also moved the Y Endstop, just to clear up the space for the cable mesh to run freely. For the bed wires I used silicone wire that is used in the RC scene, That is made to flex arround.
