FluidNC Primo Config for FYSETC-E4 board

Software / Firmware Jackpot Board / FluidNC
1

This is a working config for a Primo using FYSETC-E4 board with FluidNC. This uses series wired steppers on X & Y with standard belts/pulleys and Z configuration for 2mm per rotation.

Keep on eye on the thread for additional tuning as I start making woodchips, however this will get you moving for pen drawing.

Updated this config to support homing sensors, probe and increased amps on the drivers.
