I'm borrowing a MakerFarm Prusa i3v printer from a friend, and he has this extra Smoothieboard V1 5X I'd like to try and use. When I load a recent version of the firmware onto the board and then issue a Version command via USB, I get the following response.
"Build version: edge-bdb141f, Build date: Jan 12 2020 10:21:20, MCU: LPC1768, System Clock: 100MHz 5 axis
NOTICE: This MCU is deprecated, and cannot guarantee proper function"
Does anyone know what version of firmware, by date or commit #, that was last known to work with the 100MHz MCU?
