@rushmere3d The heart of my problem was that I simply edited the S labels to H in all my Homing scripts. Bad idea. I should have simply swapped out the old files for e3d’s new homing files. My old files used the M574 command which reset the end stops incorrectly for the update. I have no idea why the m574 command was in the original homing scripts…
The second problem was because I had not read the ALL of the docs on the pin out labels. As such I had assumed the exclamation mark was on all pinout names. I went back and ready the whole thing and found the ! Sets the polarity of the connections.
Heaters all tuned. Almost ready to print. Again thanks to all for the help.
And… yeah I’ll talk about the update in the 3d Printing Today podcast.
