Endstops, Z-Probe Wiring

Wiring

I can’t say it enough, double check your connections! Route the cables neatly and keep them well organised with tie-wraps or cable sleeves.

First here are the schematics so when you route the cables you can can see where you need to go. If you need a bigger version for more detail, you can get it here. You can plug in the motors, the hotend temperature sensor and connect the heater and fan wires. Orientation for the motors and fan is important, not for the rest.
The micro switches all have 3 connections. They are labelled COM, NO and NC. Solder 2 wires to the COM and NO connections (the 2 outer ones) of the endstops. Route the cables through the sides of the OpenBeam plug them into the correct position. It doesn’t matter which way you plug them in as long as they are in the right spot.
Do the same with the probe switch but now use COM and NC.

You’re 3D printer is now ready for use. Make a final check that the platform can move in all directions freely but without any play. The frame should be sturdy and the electrical connections safe and double checked. If all is OK than let’s move on to getting this thing up and running!
