Used wireless pendant compatible with MACH3 motion control software. WHB04S USB receiver. Works great. Pendant requires 2 AAA batteries not included. Magnetic base. The M930.m1s plugin file and Probe VB script will be emailed to the buyer once payment is cleared.
Very simple setup. Once the plugin is installed into the MACH3 folder, the unit will work with all buttons functioning. You will be able to adjust the Auto Zero parameters with the VB script editor built into MACH3.
If you have any questions let me know.
