I always thought the 300x200 heatbed was a lot for the mainboard to handle on its own. So with the mks gen board there is also a solid state relay or mosfet to install..



It is good to have because the printer supports a larger bed and I might very well find my way to the max dimensions heatbed so it is good to get ssr installed now. Also I am switching the z axis back to the a4988 drivers. While I am always trying for more steps/mm I fear the z axis is overkill at 5120. So the a4988 steppers will bring that back to 2560. Now I just gotta change a bunch of connectors and get this bad boy wired up.
