Re: Z-min - Check for a short under the resistor packs next to the 4050 (the one nearest the E0-MOT connector - RP801). My guess is that there is either excess solder, or a short under the resistor pack (the tracks are a bit weird there -will clean them up - Have cleaned them up. Have already raised the issue on Github and just provided a patch too!).
Re: FET5/6 - Can you tell me what the default output on the MCU pins that feed FET5/6 is? We have 2 free pullup/pulldown resistors over near the 4050 (one on RP801, one on RP802), so maybe we can pull the lines the appropriate way to stop this behaviour?
FWIW: I'm doing some work on RAMPS-FD and submitting patches up to bobc. Cleaning up a few component placements, etc. Basically tackling a lot of the issues that are up on Github at the moment. Admittedly, I did raise most of those issues, so thought I may as well try and fix as many as I can. ;)
