Fitting an encoder on a Tormach 1100

If I went with the 7i85 instead of the 7i75 would I be able to achieve 3 mpg's plus my spindle encoder if so what version of the 7i85 would I need to order?

If you used a 7I85S or 7I85 you could use the spare encoder channels as MPG inputs
or connect the 7I73 (the 7I85 has 5 sserial channels and the 7I85S has one) and get 4 MPG channels
that way. The 7I73 might simplify wiring and supports the 1X encoder mode which is usually better for 100 PPR MPG dials

Ok to re-cap I will order a 7i85s When you have time could you please make me the bit file to replace the tormach_mill3.bit and make P2 on the 5i25to be able to use the 7i85s.

Would this new one also allow me to use the 7i73 pendent if needed on the 7i85s

Thanks

Yes a 7I85S has one SSerial channel so its possible to add a 7I73 (or any other SSerial remote device)
if you dont need more step/dir outputs you can also use a 7I85 (no s) and get 5 SSerial expansion channels

Thanks Peter for the help I will order the 7i85s and some other bits and I will await the bit file to suite.

The 7i85s is now in transit to me. How do I find the correct bit file?
