We’ve just updated our Unified 2 firmware to version 2.22a. Unless this release addresses a bug on your machine and/or board or there is a feature you want that was added (if any) you do not need to update. If you are using our EZBoard with the EZFirmware site this firmware update will be on the EZFirmware site as well for immediate use.

Release Notes:

Bug Fixes

  • Fix Babystepping not being available on some configs
  • Moved PROBING_STEPPERS_OFF to a separate option
  • Slowed down probing speeds when PROBING_STEPPERS_OFF is enabled to prevent positioning issues


  • Added explanation about “uncommenting” to all configs
  • Merged 2208/2209 option for V4.2.2 boards as they work with the same settings in Marlin and this simplifies setup for this board for end users


Updated EZBoard Binaries to V2.22a
