I upgraded my machine from the chinese board i had to fluidnc 6x board by Bart Dring 6x CNC Controller | Wiki.js , ive done some tests after upgrading and i can safely say it works like before.
also note i am exporting the gcode from fusion 360
only one issue i encountered so if you plan be careful, if you pause a job that has multiple tools and start again, the tool change does not go as intended, it will pause, stop the spindle, and it will start the spindle with the same tool back up. i noticed this stopped it and started from the beginning again. if you don’t pause this will not happen.
