New software will often require new firmware. New software packages always come with the latest firmware at the time the software was released; however, sometimes newer firmware is available.

There are two families of firmware; one for the heads, or STM-103 boards, and another for the motion controllers, or STM-427 / STM-407 boards.

For the STM-103 Boards. Consult the table below for the proper version. The wrong version WILL NOT WORK.

Video instructions for flashing the 103 (HH/HB) Controllers: https://youtu.be/yM8QMZBTb4o

  1. Launch Repetrel ( C:\Repetrel\bin\Repetrel.exe ).
  2. Go to File > Update Firmware > Motion Controller
  3. Select the latest .dfu file for your machine from the table above.
  4. Your printer should show as "CONNECTED" in the firmware utility. If it is not:
    1. Access the Motion Controller.
    2. Change the vertical switch to BOOT CONFIG (away from the vertical switch).
    3. Reset the motion controller (small button left of the LED).
    4. You should now be CONNECTED.
  5. Click "Program" - the process takes a few seconds.
  6. IF you had to change the switch, change it back and reset the motion controller.
  7. You are done.

You should not have to flash new firmware on any heads, although some values have changed; please see the charts at Cold and Warm Flow and Hot Flow for details.
