Marlin MakerGear M2 (Rev H) Marlin 2.1.3+

Article Placeholder

I wrote the official example configuration and this article again the last model Revision H. We will discuss the differences in other revisions to assist you in getting your specific revision work as well. But I am unable to test them myself. Some of the original firmware notes seem incorrect but many of the details about revision differences are available here - https://makergear.zendesk.com/hc/en-us/articles/360022528292
