Was working for a while, but I decided to test sensorless homing and it was acting weird. Working fine on X/Y but not Z. So I said well, probably dumb to use it there anyways, so I backed out my changes, added back a modified 2209 (pin clipped) and said okay use my mechanical endstop.
However without changing my configuration, the Z starts moving up to home (reverse from before I started messing around with sensorless (and I didn’t change the Z config in my printer, other than initially setting the endstop to a virtual of the 2209_z pin…
I’m kind of at a loss what it could be. I’ve cycled, I’ve refreshed the config file, I’ve cycled klipper etc. hmmm never cycled octoprint, but that should not matter, buuut… no change.
Anyways pertinent info.
CR10S
SKR1.4 Turbo
Bigtree 2209 drivers, X Y are complete, Z and E0 have the pin cut. X and Y sensorless is working nicely.
Klipper (can’t actually figure out what version I’m running)"

So again try to home my Z, it starts moving up (and I don’t have my plugs reversed :)) then the system halts with the following errors: Same config that has been running for a month +, until I revamped the wiring and such.
