Teacup firmware supported this venerable controller for many years. It features a dedicated extruder board, which communicates over serial and was often used with DC motor driven extruders.
We, some Teacup developers, happily keep this support and maybe even enhance it. At least it partially made its way into Configtool. But if there are no users of such controllers left, doing so is a bit pointless.
Gen3 users, please speak up!
That said, if you want to decide later and Gen3 support happened to be gone until then, you can still check out older versions of Teacup, of course, and use that. Teacup Firmwares history (which began in December 2009) won't be wiped.
