Ooznest CNC OX router with Mach3
As you can see the build is almost complete. The final task is to get the limit switch installed and wired up.
I’ve used a 4 port RJ-45 socket to connect my steppers and limit switches. Only 4 of the 8 wires in the Cat5e cable are used so I can use the two of the others for the switches. I will wire all the switches in series as I have done on my CNC hot wire cutter to pin 11. This diagram shows how https://drive.google.com/file/d/0B5VqnA81FKH5eWx4VDE1RkFOREk/view?usp=sharing.
This allows me to swap back to my hot wire machine just my plug in in the Cat5e cables back into the towers and run up a different config in Mach3.
The E-stop is also wired with a Cat5e cable back to the controller which has a RJ-45 socket installed and connected to the E-stop on the TB6650. The joypad works via a plugin on the Mach3 website http://www.machsupport.com/software/plugins/ and can be configured to move all axis and button set to a function of you choice. Works really well.
