I’m a newbie in CNC construction and I going to create a dispensing robot. I create the concept of the machine - It moves as I need - except the 4th axis… all four axes must have endstops. my prototype works on Marlin firmware (with all restrictions - only three min endstps) - but I’m going to move to 32-bit core and thinking about Smoothieware firmware and asking for your help - where I could find an example of the config file for four axes with own endstops?
Have you tried just setting delta_min_endstop and delta_max_endstop just like the alpha, beta, and gamma axes? I see no axis limitations in the endstops module.
