The controller board supplied with my 3018 Pro appears to match the picture above with one exception – the circuit board is red.
This controller is supplied with GRBL 0.9 installed. The 3018 Pro is supplied with the necessary firmware flashing tools to return to 0.9 if you decide to update and it goes wrong.
I have since flashed the controller with GRBL 1.1h to allow use of position homing on X & Y axis. It was necessary to tweak the configuration of the GRBL firmware so took the opportunity to update at the same time. Happy to report, so far, that version 1.1h appears to be fully compatible with this controller board.
