    While I like the addition of feed speed override and spindle speed override it’s still missing the ability to control a 4th axis. Barton Dring says he plans on adding additional axis to grbl but until then I’m not sure if this port is going to expand as rapidly as many hope.

    You can currently purchase 32 bit 4 and 5 axis controllers from China that eliminate the need for Mach 3 for reasonable prices such as this: https://www.banggood.com/Machifit-CNC-5-Axis-Offline-Controller-500KHZ-Motion-Controller-Replace-Mach-3-USB-for-Engraving-Milling-Machine-p-1417786.html?rmmds=search&cur_warehouse=CN

    I’m currently working on an interface to replace a proprietary controller. While I think the esp32 grbl port is the way of the future, it’s in dire need of at least 4 axis control and many want 5 axis.
