Installing Python on Windows 10 – for Makerbot Firmware Upgrades

This is a quick article on which Python version you will need to assist with manually uploading the Makerbot Firmware.

If you are trying to manually upload firmware for the Makerbot Replicator 2, and you try to use the most recent version of Python (version 3.8 at the time of this writing), it simply will not allow you to run the Makerbot firmware upload tool. If you see the following error when you run the tool, you will know what I mean:

C:\Users\%username%\Downloads\winBotTool_76_G\winBotTool_76_G>Traceback (most

To fix this error above, simply remove Python 3.8 and install Python 2.7 from the following link:
