When you're getting started, in order to make sure that your Industrial CNC Router doesn't run into the side of the table, it can be a good idea to set up limits in your Mach 3 software for safety. In this post, I'll you how to set your soft-limits, which means that the software will stop the table automatically before this occurs.
*Please make sure that your motors are properly tuned before setting the limits or they won't work properly.
1) The first step is to go to CONFIG/PORTS and PINS/INPUT SIGNALS. Make sure that all of your limit switches are disabled. (a red X for each row) See attached picture.
If you're using your Homing Switches, you can ignore that, and simply "Reference All Home" so that your "Machine Coordinates" Home is set automatically at Zero.
