Re: No Parallel Port

Ray,

I've wired myself a little gender bender to get the wiring on my Camtronics
controller compatible with EMC and I can now jog the axis!

I'm looking for documentation for the INI file so I can setup the motors
correctly. Forgive me if  I've missed something but looking through the
handbook and the EMC site I can't find a comprehensive description of the
INI file parameters. Is there one available ?

In particular I'm trying to setup my steps per inch. I beleive that I use
the Input Scale and Output Scale parameters to do this but I've increased
these and yet I don't see any difference in the output.

At the moment if I enter a command to move an axis 1 inch I get an output on
the motors that looks like 1/4 of an inch. This suggests that I need to
increase the Input & Output scale to 4000. I've changed the ini file but I
don't see and change in behavour.

The other issue I have yet to tackle is Backlash compensation. Do I just
enter my values into the ini file as inches or steps ?


Any ideas ?

thanks

Phil
