So i just finished a build based on the HEVO using a duet 2 wifi w/ a Duex5 and triple independent Z steppers. I finally have all the motion moving the right way (bed drops away from the nozzle when homing and then moves up), the bed goes up to 0 and down to 500, the issue is when i try to home it, it tries to home at 500 (the bottom of the printer) even tho when it homes it will set that to 0.
