Upgrading Monoprice Voxel 3D Printer to a FlashForge Adventurer 3!

The Monoprice Voxel is an excellent small form factor fully enclosed 3D Printer. There are a few pitfalls however, the first of these is that the Firmware and Software have not been updated since 2019 by Monoprice. The good news is you can upgrade both of these by flashing new firmware from the FlashForge Adventurer 3!

FlashForge did a white label version of their Adventurer 3 printer for Monoprice, and they still sell it. They also are constantly making improvements to their “FlashPrint” software and are upgrading their Firmware.


Upgrading the firmware in the Voxel is a pretty easy task and made easier by the instructions that u/Jimmy0x52 on Reddit posted a couple of years ago. These instructions need a few very “small” updates that I have created below.


  1. Visit https://drive.google.com/drive/folders/1AX-GupCoJoM6Qhpwi5jL2lG6fnh4O4Dk and download one version newer than your Voxel’s firmware.
  2. Unzip into a new folder
  3. Format a USB stick. (Mac=MSDOS FAT, Windows=FAT32)
  4. In the firmware folder open the file flashforge_init.sh in a text editor (note: Use NotePad++, Sublime Text).
  5. Delete lines 22-31 (See below for the lines to delete)
  6. Save the updated file
  7. Copy all of the files from the firmware folder to your formatted USB Drive
  8. Power down your Voxel, Insert the drive into the front USB port, Turn the Voxel on. You should see the update screen. In a few seconds it will make three chimes. You can remove the USB and restart the printer.
  9. Finally if the Voxel is connected to the internet the firmware will automatically begin updating multiple times until the latest firmware is loaded.
  10. Your Voxel printer is now a FlashForge Adventurer 3!!!

Lines of code to comment out that allow for the Voxel firmware to be overwritten by Adventurer 3 firmware:

if [ ! -f $WORKDIR/screwflag ]; then 
	if [ "$1" != "" ] && [ "$2" != "" ];then
		if [ "$1" != "${MACHINE}" ] || [ "$2" != "${PID}" ];then
			echo "Firmware does not match machine type."
			exit 1

Now that your printer now is a FlashForge Adventerure 3 you can use the latest FlashPrint software found here:
