I've updated my old 19v M2 with RAMBo rev 1.3 with the latest Marlin firmware, currently v2.1.2.5. It works fine with this config. My focus has been on getting the baseline working as it was with the original firmware, but I've started including some of the new features, though some need to be enabled in gcode. (I've kep LIN_ADVANCE at 0, and I have not done anything with input shaping yet, though perhaps the Y axis is the most plausible candidate.)

Edit 2025-02-18: I've updated the config, which I have now built with arduino, uploaded to my printer, and I've been testing a bit. This configuration has taken inspiration from Makergear's published configs, djw's description, and new possibilities. The current config features:
When I tried going with the original PID values, the printer kept giving THERMAL_RUNAWAY errors, even though there was no thermal runaway. Apparently the PID values don't carry the same meaning across major releases of Marlin, so PID values need to be updated when doing major upgrades.
Fortunately they shared their config way back when, and it's still available at
