When you press the up arrow key, the gantry should move towards the back of the machine (away from you), and your Y digital readout in Mach should count up (positive direction). It can be helpful to stand at the front of the machine (facing the gantry, looking at the Z axis) in order to visualize the coordinate system.

The diagrams below show the correct installation of motors and sensors on the machine: On machines with slaved axes, it is particularly important to verify which axis is the primary Y, and which is the slaved Y (generally the B axis, however in some cases the A axis, depending on the controller you have), as the Y and slave Y sensors (again, B or A) need to be matched with the correct axis of motion for auto-squaring. Homing your machine requires moving each axis towards its designated home sensor, so it is important to make sure your motors and sensors are installed in the correct physical positions on the machine. The switches themselves are fairly simple, but setting up the coordinated motion of the machine for homing is best done with the following step by step approach.

The following instructions go over the hardware and software settings required to set up Homing (including auto-squaring of your gantry for dual-drive machines) and Limits with our inductive proximity switches. These archived proximity limit switch instructions are for those using Mach3 CNC control software, or setting up limit switches with older Avid CNC electronics systems (CRP300 or CRP500).įor setup instructions with Mach4 CNC control software or current Avid CNC Plug and Play CNC Control Systems, refer to our Proximity Limit Switch Instructions.
