How to disable Axis from homing in RDWORKS V8 in the event of a failed home proximity sensor

step-2 rd works disable home

A common failure of chinese laser engraving machines is failure of the home sensor. Each time the machine is powered on, the laser head will travel to its zero position, most commonly the top right of the machine. A sensor tells the controller when home is reached and sets that point at 0mm in the […]
