Hello Marlin FW community,

I am a research graduate student using an Arduino paired with a RAMPS 1.4 connected to 2 stepper motors and controlled by a Raspberry Pi 3 as a dual scientific syringe pump. When I go to do the delta auto calibration however, I am running into issues. The auto calibration starts to work, then runs into a homing failure and ends the calibration. I am fairly knew to this experience but have been using this as a learning experience. Any and all help you can give would be greatly appreciated. Thank you.
