I am desperately trying to install and use an mpg wheel, not the pendant - just the wheel. It’s going on a panel im making.

My machine has one of those xhc Chinese Ethernet controllers.

My wheel has 4 connections A B 0v vcc

My controller only has a 24v power source, so I fed it through an external 5v  source that isn’t tied into the Cnc - ran the A B wires to inputs.

It doesn’t work, there’s nothing in my controller plug-in that offers mpg - wxcept the wbh04 pendant. 

Can I add a second port to my pc, am interface board? Help! Lol

Connect the external 5V ground with to the ground of the 24V. (*only the ground)

need to be a bit carefull with that sometimes you can get interfearance from the motors if the 5v and 24v are ground connected.

Brian can u give a little bit more info like what u r trying to do beside just hook up the mpg...did u get the plug in from this xhc board ? If mach 3 does not have a plug in it will not see the encoder and that is what the "wheel" is acting as. What type of BOB r u using ?? Does the BOB ( break out board ) what an encoder connection?? There is alot of info missing for us ( the fourm) to be able to help u .... we can't see what u see so u r gonna have to explain in detail what u have and what u want that equipment to do
