Let me answer a number of questions that I have received via email and PM:
The pendant buttons will operate any (and only) macros or operations that are currently on your WinCNC screen
Other actions or options can be added (by yourself for free) or for a small additional charge
Any operation or action that you machine is capable of performing can be assigned to a button and can be operated by a pendant button.
If you have a Branded machine, you should contact that OEM to add your pendant. They may refer you to me, but your first contact should be the OEM's Tech Support. DIY WinCNC users may contact myself or WinCNC directly.
