I plan to build the MPCNC with my dad. I already own an ender 3 to print the parts. From upgrading the printer (I installed an mks gen l board) I still have the stock ender 3 board. As a CNC does the same control work as a 3d printer and both run Marlin, would it be possible to use this board to control the MPCNC? The board supports 4 stepper motors and 3 endstops, anything else I am missing?
Thanks for your help,

If you can flash marlin on it you should be able to tweak the settings to make it work. I have no experience with that board though.August 6, 2019 at 11:42 pm #108702
It is shipped with Marlin but I flashed it to use TH3D version before I switched boards. Thus no problem flashing and tweaking marlin settings. What I read is that the X and Y axis use two stepper motors so it totals to 5. Do I need to have a board supporting 5 stepper motors or are the ones on the axis running in parallel?August 6, 2019 at 11:51 pm #108703
if you plan to use Dual auto-squaring firmware you need 5 independent drivers.August 7, 2019 at 2:51 am #108722
Would you recommend adding the dual endstops? If it’s worth I have no problem buying another board, but when it’s not that much of an improvement I am happy to give the board another meaning.August 8, 2019 at 12:55 pm #108984
Dual endstops aren’t needed for almost every usage case. I’d go with the board you have, tweak the software to work with it as needed and wire the pairs of steppers in series instead of parallel. If you find you have a need for dual endstops in the future it’s a relatively simple process to swap out the electronics.September 1, 2019 at 10:37 am #111635
