In this guide, I will be walking through how I upgraded my Monoprice Maker Ultimate to Marlin 2.0.x using the pre-built version offered by dot-bob. The installation in this scenario would be upgrading from Marlin 1.1.x that was installed previously and using the Firmware Updater plugin in Octoprint.

Here is the current setup I have:

• Firmware: Marlin 1.1.x
  • This was also using dot-bob’s 1.1.x firmware that I upgraded the original firmware to when it arrived
• Octoprint version 1.4.0 that is installed on a Raspberry Pi. It is connected to the 3d printer using a USB cable.
  • Octoprint has an Octopi image that can be burned onto an sdcard to get you up quickly in their downloads section.
