Z Homing issues after Z20 install

After installing the Z20 slider, it was failing to raise the slider during homing and therefor never homed correctly. I followed the Stall Homing video and adjusted the Max Current upwards in increments of .1 until it started raising the slider, which ended up being 3.6amps. But now, I have the opposite problem and it won’t stop at the top and I have to hit Estop.

Any ideas on what to do next?
