Mecanumeric MF2040 LI retrofit (Pantograph)

One thing about optical encoders, they really don't appreciate contamination. If oil or coolant get into them, it will generally really screw them up. Even if none of the electronics with are hurt, a little dirt in the wrong spot or on the wheel can be very bad. Also when they get really old sometimes the LED source can get weak or fail.

Yes, that could definitely be the case. It's a very old machine—27 years old—but I decided I want to give her a new life. The structure is really solid, plus it has vacuum and lubrication for aluminum, which is great.
So, I want to do this retrofit, and I think the setup I posted here should get the job done. The only thing I have to do is adapt the old motor frames (they have a small gearbox), because the old motor is 89x89mm and the Leadshine is 80x80mm. I hope it won’t be too difficult.
Once the machine is up and running and I’ve done some work with it, I can swap the spindle and install an automatic tool changer. That would be so cool!

Do you have any general advice? Does the setup look good to you guys?
By the way, I’ve installed the LinuxCNC ISO on an old PC with an Intel i5. Now I’m just waiting to buy the Mesa board and start configuring everything.
