I'm currently replacing the BFB electronics of a BFB3000 with an Ultimaker 1.5.6 pcb. Keeping the old frame, motors, sensors and wiring of the BFB3000. I stumbled upon a problem with reading out the endstops. :? The endstops are reed contacts, but the cables run along the wiring of the stepper motors. The Ultimaker endstop connectors take up some interference from the stepper motors. This was no problem with the BFB board, because the sensors had a small network with 2 resistors and a capacitor. What could this schematic be and look like? Further twisting the cables (they are only partially twisted) could bring a solution, but I'm wondering if an network could also solve my problem. Any help is greatly appreciated.
