I have a SKR Pro1.2 and TFT35 E3 V3 screen, I’m trying to source longer ribbon cables to lift the screen away from the board. Does anyone know where I can source them and the codes.
I don’t have an answer for your specific question, but, if you are not using Marlin mode, you don’t need to replace the two, usually gray, cables. As for the remaining cable of five (usually black) wires, any wires with Dupont ends will fit the connections. Unfortunately, I only see Dupont wires sold in “bulk” (120 count), but they are not too expensive. A 120-count set of 16" wires, runs $12 on Amazon, and a set of 20" wires runs $14.
Be aware that longer leads can lead to electrical noise issues. I had a problem once with a printer in marlin mode and the workaround I found was to make up a shielded cable and use touch screen mode.
