Hello...
I have been searching for a board to make a small cnc...
I thought that this board is perfect for that...
Today many people uses grbl or marlin to make small cnc...
But there is a few boards that is prepared for that..
Like the 3018 - 3018 pro....
I think that the only thing missing in your board is a output for the spindle / laser...
Instead of the heatbed and extruder...
Change that for the spindle with pwm and laser....?
If you can make a board like AIO with that..
And maybe work a bit on the firmware to make it even better....
Maybe you can sell very well in that place of cnc controllers boards for cnc...?
I don't know if I'm right or not...
It's just a idea....
