Been a long time. I've been having grief with my Hemera on my FT-5 R1. I upgraded a lot over the years. I have the 713 Maker base and side rail holders. The Hemera just seems to jam. I replaced the hot side components which helps a bit.
There are lots of new features in latest Marlin I'd like to try. Does anyone have a ver recent Marlin firmware that will work on the original mks that they would share?
