1. Hello, thank you for posting this, I found it extremely helpful.

    I think I found another manufacturer using the Dlion firmware. The XViCO Pioneer (sometimes known as the X3?) looks to be using it, judging by the firmware I dumped from the board. The board itself seems to be a cut-down version of the original Dlion board, and can be bought on AliExpress, though I have yet to find the source for the firmware.

    See my website (actually blog) for recent entries on this printer and board.

      Hey Jim, yes, I think you’re right! I am trying to see if I can get a review unit of the xvico later this year for some further investigation. I noticed you can also purchase a motherboard with dlion directly on aliexpress. I’m also curious about any connections with dlion and the lerdgeX boards.

      A nice thing all of these boards have in common, is they are based on the STM32F103ZET6 cpu, which has a generous 512k of flash and 128k or ram – I’m making some slow progress to getting a working build of marlin 2.0 together, which I reckon would be easy to load up on the dlion and lerdgeX boards, with some minor pin configuration changes. This is also the same cpu used on the MKS Robin.

      Thanks for your comment!

  2. I am so glad I found this information! I got HERE by googling Xvico Pioneer X3, which took me to Tingering and Fiddling. I have the Xvico X3. Need to move the bed FORWARDS somehow. Would really like to upgrade the firmware to Marlin 2.0. If I can figure out how to save this link, I’ll follow and support your efforts somehow.

      It’s challenging, since every motherboard is different, and I don’t have access to the Xvico board for testing. I also can’t find anywhere to buy it separately! The easiest option to get started with 32-bit Marlin 2.0 would probably be to buy a BigTree SKR motherboard.
