To do this “Limit Switches Stop” checkboxes should be checked. Triggered limit switch should stop machine.
To verify that all limit switches are working, trigger switch with hand and position display will become red or purple. Two limit switches on X, two on Y and one on Z axis. Machine that I will use has 5 limit switches. For now it is important that everything is set to zero. “Empty” tool should be selected with with “Machine/Tools/Select/Empty” and tool offset should be set to zero with with “Machine/Tools/Zero Tool Offset” command. Working offset should be set to zero with command “Machine/Offset/Zero”. If your SPU is not yet set please read SPU tutorial: How to set Steps Per Unit values?įirst we need to set offsets to zero. If position display changes for 100mm then machine should move 100mm. You should verify that distances in all directions are correct when machine moves. “Steps per unit” settings are already calculated and set. I use metric (millimeter) units but everything is same with imperial (inches) units except numbers are different (1mm is apporximately 0.03937in). I will use my router machine as an example but you can do it similar way on all machine types. I will try to show you how to setup your CNC using PlanetCNC software.
