Got the C Beam setup. Couple of niggling issues that i need advice on its likely cause and resolution. Noise - The machine is noisy. Been trying to identify the source of the grating sound, X axis seems to be running nice and smoothly when it suddenly decides to start making a grating noise. Turned off the mains to prevent damage. Maybe my stepper motor is too heavy and the existing supports are not rigid enough to offer sufficient bracing? Endstops - Set up the limit switches in a basic NC configuration. Hooked everything up as per the guide but nada. It still works when i manually trigger the limit switches. I am grounding the setup via the ground circuit on the stepper drivers (It is connected to the same ground as what is indicated on the guide for the endstop configuration on the GRBL guide. Did I miss a step? Do I have to configure and modify the config.h file to set it up? Heat - I know the stepper motors get hot, but what is acceptable heat levels? I have set the DM542 to 1/2 current at idle. My X axis get much warmer than the Y and Z axis. Cable management - What are your preferred methods on managing the cables on your machine? Thanks for your comments and advice.
