Cnc Diy
Thanks for your kind answer.
I guess measuring the exact spindle position would be the least of my problems. As this application would be merely a diy project, precison and repeatability are not that critical. Furthermore, these parameters depend also on the milling machine itself. Which is an old one, so the mechanical precision wont be very good. If i could realise an accuracy of 0.1 mm, i'd be glad!
Referencing would'nt be a problem if i would use absolute encoders?
My goal would indeed be to mill all kinds of figures or patterns, at least in 2-D, meaning that X and Y spindle need to operate in a coordinated manner. I suppose you could call this CNC?
My bottom question is then if someone has ever programmed something similar in S7? I admit that a real CNC controller would be the correct solution, but since this is a diy application, money matters. And i have a 315-2DP and 3 MM440 with DP interface on the shelf. So i would only need to buy the encoders.
Of course, if someone experienced in this matter could give me some tips & tricks, this would be very usefull for me. (Maybe warn me that i'm dreaming, that this can't be done?)
Anyway, thanks in advance for your much appreciated answer (even in German).
And maybe practicing English is usefull for both of us?
