![]() ![]() ![]() When Z home switch triggered, Z stop for a short time ( $26) and back off a distance ( $27).Z Axis will move up (positive) with Fast Rate ( $25).$23=2 Bottom right of your work area to be the home location.īy default, the homing cycle goes through the following steps:. ![]() Default setting ( $23=0), the home location is the top right of your work area, with the spindle all the way up.The homing directions are controlled by setting $23 setting it to a value defined below: Homing direction Type $22=1 to enable it, $22=0 to disable it. This will result in this wiring:Įnable Home Cycle and Setup Home Parameters Īll the common lines go to the arduino's GND, the NO lines go to the pin for that axis. Use of ( NC) instead of ( NO) is enabled by configuring $5=1. In this case, we are going to use two terminals, normally open ( NO) and common ( COM). One is common terminal ( COM), one is normally open ( NO) to the common terminal and another one is normally closed ( NC) to common. Limit switches usually have three terminals: 3 digital input pins are used for signaling Grbl:Īnother place that explains the Limit switch configuration: Wiring-Limit-Switches ![]()
