Ebosa 140 CNC retrofit

Hello,
I am in the process of retrofiting a ebosa 140 CNC lathe. It originally had a Siemens 3T control, Siemens brushed servos and Siemens brushed spindle motor with thyristor drive.

I will reuse the spindle motor with its drive, but will replace servomotors with new Lichuan ethercat motors.For IO I will use Beckhoff modules and Mesa hardware (6i25, 7i85, 7i73).Here are some pictures of the build currently.

 
This is the control cabinet, wiring still in progress.

 
And this is the control panel, laser cut stainless, cherry switches and potentiometers for overrides. screen is a chinese 14 inch touch screen.

Really nice job on the control panel.

Thank you Mark!

Here is a picture of the back side of the panel, 7i73 reading switches, 2 potentiometers and mpg encoder.
It also drives 30 LEDs under switches (multiplexed). The multiplexing is currently done in hal but I will try to write a component for it.

 

And this is a custom power detection board. Basically just 12 AC optocouplers and a relay output to detect a open breaker or motor overloads.

 

Also do you insert pictures in posts as attachments or someway different. On some pictures even if I compress them, forum still complains about large file size.

Nice work.

I downsize pictures to 1000 pixels on the long side before uploading them.
