Recovery Method - Motion Controller

If you received a Select Mini V1 or V2, black or white and the UI looks like the photo, do NOT update the firmware with any currently available firmware version. Some V1's & V2's, white or black do NOT use the same firmware as previous V1 & V2's.

If your Select Mini has Motion Controller version 31+ or higher pre-installed, do NOT use V1 Motion Controller firmware. There is not any firmware updates yet available for the Select Mini V2.

If your Select Mini has UI Controller version 106.2 or similar pre-installed, do NOT use V1 UI Controller firmware which is any versions 33 through 42.

I know all that is a bit confusing and may not make sense to anyone other than myself. Basically if you have a Select Mini V2 or V1 that has the UI seen in the picture, don't update the firmware.

Do you have a black screen after falling victim to updating the firmware after watching a video or maybe you outright ignored the warnings? You can contact me in one of the following online community groups so that we may schedule a time to get your printers display back to the way Monoprice intended it to be.

(This is only a temporary fix. When the V1's have definitely stopped shipping and fully tested firmware for the V2 is released, this process will not need to be done.)

Do not update the firmware before completing a few prints.
Updating the firmware before using the printer introduces another variable to the troubleshooting session you may have to go through.

Note: If you have trouble updating, please format microSD card or use another microSD card and try again. Try a microSD card that is 4GB or less formatted with FAT. The printer can be picky at which cards it will update from so try a few cards.

The recovery method can be used as follows:

  1. Copy any version of “update.bin” Motion Controller firmware file to the root of the microSD card.
  2. Copy the file named “fcupdate.flg” file to the root of the microSD card. If this file is missing it can be derived a few different ways listed below.
    • Creating a file and name it “fcupdate.flg”
    • Copying an existing file from your computer and rename it to “fcupdate.flg”
    • Downloading from MP Select Mini Share - Google Drive Firmware » Individual » Motion » fcupdate.flg
  3. Put the microSD card in the printers microSD card slot/reader.
  4. Power on the printer. When the printer is powered on, it will force the update.
  5. IMPORTANT: After successfully updating, remove microSD Card and delete the “fcupdate.flg” file. You may also delete the “update.bin” file.
    (If flashing to a different version then follow the steps below)
  6. Export/Save any calibration you have done as the next step will erase/reset everything back to defaults.
  7. Reset EEPROM using “M502” and save EEPROM using “M500”

  8. (Optional) Run PID Autotune

Trouble recovering?

  • Format microSD card or use another microSD card and try again.
  • Try a microSD card that is 4GB or less formatted with FAT
  • Verify the x-axis endstop is not pressed in.
