Thanks for your reply.
I will have a look at the servos to find out what cind they are.
I see some talk about closed loop around, is this possible to achieve with the original servos?
Have been looking around the web a bit about this retrofit subject, and must say that I am a bit worried that this is pretty difficult stuff.
Is there a detailed guide to how all this works, thinking all the hardware and what parts work together.
Or perhaps som web pages that can inform me to better understand the whole thing better.
My brother in law is very famillar with PLC, so that part is possible to do.
Annyone that hav an opinion on what the costs will be?
