    A simple GRBL shield using your existing stepper drivers will set you back about $5

    Get an arduino Due to go with the GRBL shield and run G2Core and it will probably be a huge step up on the Chinese one.

    There are others, from Azteeg, Tiny, Smoothie, etc. but they have stepped drivers built in.

    It will require some fettling, but is pretty straightforward and there are plenty of instructionals on the net - just google ‘upgrade K40 controller”

    Heaps of help on the google plus K40 community: https://plus.google.com/communities/118113483589382049502

    As you don’t need much motive power, any 3D printer controller, Ramps board, TinyG, etc. will work, but you can add more functionality (like Ethernet connection, on-board storage, etc.) by selecting the features you want - just make sure the board you buy is easily configured. Open source or similar will be fine, and cheap.

    If it was me, I would choose a 32-bit controller with Ethernet.

    an Azteeg with the fewest number of drivers you need - x an y axes, plus bed height adjust?

    Controllers

    But if price matters, $25 will get you running from China

    I use the Cohesion 3D on my ACRO and K40 and works great with both. I has sockets for stepper drivers but also has a header available that will plug into the socket to connect external drivers.

    Cohesion is a Smoothie 32-bit variant, same as Smoothie, Azteeg, MKS, etc.

    After looking at various K40 machines, some come with external drivers, some use an integrated board.

    But, most of them seem to use Nema23s, so pretty much anything with a decent stepper driver like a DRV8825 will work fine.

    You can get a decent 32-bit with touch panel display running Smoothie for ~$100 on AliExpress. That would be a step up from anything shipped as standard on a K40
