+# Voron 2.4 AB Plug (Microfit 1x4)
+This mod is to add a plug to the gantry to connect the A & B motors. These mount on the underside of the rear extrusion facing the motors themselves. There are 2 different designs. One that supports a Microfit 3.0 1x4 with panel mount ears and the other is _without_ panel mount ears.
+
+Both these plug types have been found on the Lineo harneses. Check which one came with your harness before printing.
+
+It may take some work to get the connector to fit.
+
+**Pro tip: If you would like the screws to be facing the rear of the printer you can mirror the model in your slicer.**
+
+Thanks to [Rama#6392](https://discord.com/users/627740419559653387) for the [orginal mods](https://github.com/Ramalama2/Voron-2-Mods)!
