Hi,
are all of the six axes independent or are some slaved to others?
Even if you require all 18 inputs then yes you will need another board but you will still need inputs. If you think you can get away
without decent limit and home switches with a 6 axis machine you'll struggle.
If you bought another C10 then:
Port 1 outputs 1,2-9,14,16,17 =12
inputs 10,11,12,13,15 =5
Port 2 outputs 1,14,16,17 =4
inputs 2-9,10,11,12,13,15 =13
Port 3 outputs 1,2-9,14,16,17 =12
inputs 10,11,12,13,15 =5
TOTAL outputs =
inputs =23
Is that enough?
If not you need to extend capabilities with a PLC.
And that is exactly why I am really starting to hate this DIY hacker crap
Then go buy a Seimens 840, $20,000 plus!
