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.

 So, just arrived the order for my retrofit .  I bought Mesa 7i76EU (i've done the configuration of Linuxcnc in a hold pc), than  Leadshine ELM1  , 3 of them 750w and one small 400w  and the drivers  EL6 for all the motors with different power supply. Im bit struggling because i can't connect the Motion Studio software to my driver for some tests idk if its the cable or other. I need to do a bit of wiring, and discover where to plug the brake of the motors , becausa i mounted all but i don't understand if i have to wire it with a another circuit with relays and a powersupply or if i can control it from the driver , didn't discovered it yet i need to check the schematics a few more times. If someone has any advices , or any experience with Leadshine motors and driver it's appreciated.
