[Bdi4emc-help] problem with BDI 4.3 and ppmc

Thank you for your reply. We (my brother and me) think that EMC is great.
This has gone pretty easy up till this point.

I had already worked out the EMCIO = ppmcbridgeportio from Jon.

I had asked him about the ENABLE_INDEX and he has not replied yet, I think
he is having Encoder problems with 4.3.
I don't have any documentation that says what ENABLE_INDEX is so, not sure
what is does or what it should be set to. I think it is set to "x" in the
default .ini file.
Do you have any suggestions for this parameter?

Is there any documentation on 4.3 or source code that I could look at to
help work through these problems?.

I did some preliminary tests with the help of Jon Elson back in April. Only
had one motor attached, but it did spin up in response to MDI and jogs. One
of two things spring to mind..

1) You are using the wrong IO controller - Set EMCIO = ppmcbridgeportio

2) Alternatively, the ENABLE_INDEX for each axis needs inverting.
