Re: All axis only move in positive direction

I finally got my machine to work correctly but only after completely disconnecting all stop switches and then crimping the connectors to make sure all wires to the switches and the board had solid contact. I don't know exactly why this worked but I was able to run a complete program and finish my ...

Re: All axis only move in positive direction
