It is far more flexible AVR Grbl due to the flexibility of the ESP32 I/O. There is a cpu_map.h file that maps the pins to the features. If I get get a service to build some the cost could come that should work. The cost will be about $40-ish (without ESP32 and drivers). I have a few extra to sell and will likely start selling more on Tindie. The design will be released as open source as soon as all testing is done. With router/lasers, there is much more manual jogging, probing, fixtures, etc and Grbl just feels better for that. The work offsets, real time feed rate overrides, fast feed holds are much better. I have used Grbl and Marlin on many projects, but I personally like Grbl far better for routers and lasers.

Serial Bluetooth for streaming via PC or phone.Much more reliable and convenient than streaming. This has a similar functionality to Octoprint Wifi (Client or AP), Bluetooth Serial and USB Serial control.This helps if you place the controller in an enclosure. Each has a low pass filter to help with noise. Easy connection of home/limit switches.Spindle / Laser PWM (5v) output with safety interlock.This can control AC and DC spindles or be used for a vacuum, coolant, etc.

The X and Y can optionally use auto squaring ( video) if you install (2) home switches per axis.

They are also hardwired to run in opposite directions as required by the MPCNC design.

The X and Y motors are ganged in hardware or firmware.

A stepper driver for each stepper motor (5 total).

These are the special features of the controller I am working with a friend to get one built in the next week. I tried to address all the basic needs of the MPCNC, but I have not used one yet, so I hope I got it right. FWIW: I designed a custom controller for MPCNC and Grbl_ESP32.
