Prusa i3 Control Board Replacement

so lots of fun with my board.. not heating the bed.. replacing parts left and right.. next part the board..

image is my board now.. says MPX in one spot and Base v1.3 in another..

so question is.. whats the replacement.. cant seem to find a match.. I see things that
look the same.. but say MKS... not sure what all the initals stand for.. just want
to find a replacement.. maybe even get a board that can do dual extruder in the process ?

mks is the company

other companies that clone this already clone board replace the mks with their own initials

Any reprap board will do... the only issue is plugs will be different...

MKS BASE V1.5 looks to be pin compatible..

These are ultra cheap boards, they don't have anything extra on them. no support for dual extruder.

thanks.. found one on Amazon..

so can you just swap out ? or do you need to do any config or firmware changes
to make it work ?

You need to install firmware, hopefully your suppler provided this

You also need to copy over any eeprom settings m503 to see them, enter each line into the new machine then save with M500 (resuming something like marlin)

Now if you cant get firmware from your provider... you have to work out all the parameters of your machine and build one. This will take some time.
