Hi I am converting a Tree Journeyman 325 to LinuxCNC. The XYZ analog servo controllers all work so I need 5 encoder inputs: X, Y, Z, Spindle, MPG jog wheel. I have a 5I25 and 7i76 from a previous mill conversion but I don't think they will be useful.
Is a 7I95T a good match? I may want to use the 7I76 for additional IO.
Thanks
You might want to start a new thread if you have further questions, but here's a quick answer:
The 5i25 can work with a 7i77 (or 7i77D) DB25 daughterboard if you want to reuse it. You'll need a computer with the appropriate slot, of course.
If you want an 'all-in-one' board then the 7i97T is the analog-output board you need, not the 7i95T. The 7i95T is for step/direction output.
Either of the above options will have enough drive outputs and encoder inputs to work with your Tree. Note that your MPG, while technically an encoder, does not require the same high-speed encoder input that a servo drive does. The MPG can be connected to MPG-specific IO on the above boards (taking up two input pins), leaving you with two spare drive outputs and HS-encoder inputs.
I've not personally used Mesa analog-out boards, so
please review your drive command signal requirements and verify the above boards outputs and encoder input signals will work with your drives and spindle control.
