SKR Pico and Microprobe Not Working

As described in other issues, I am having trouble getting the BTT Microprobe to work with the Pico. I have everything wired up correctly using the servos and probe ports on the board, have removed the jumped for sensorless z homing, and have made sure to add what I thought were the necessary values in to my printer.cfg and btt_microprobe.cfg files.

However, every time I try to run a home or a calibrate probe, it will deploy the probe and the bed will just continue going up crashing in to the nozzle.

probe_stow and probe_deploy both seem to work.

I'm at my wits end here honestly. I have tried 2 separate probes that I purchased to rule out the chance of me getting a dud probe or wiring it incorrectly and damaging it myself.

If anyone is able to help me out I would be super appreciative.

Here is my printer.cfg as it is right now.
