Re: [CAD_CAM_EDM_DRO] EMC Question

Hi Tim,
I did try to set 'steppermod.o' in emc.ini and it aborts with File Not
Found. I found 'univstepmod.o' in the module directory but when I enable
that one it replies in the console with Unresolved Symbol errors and aborts
EMC.
Seems about the only one that works properly is freqmod.o. I'm thinking
that I'm missing something since emc.ini was setup for use with Servo-To-Go
Card.
So, when I use another module what else do I need to change? Does anyone
have a sample emc.ini I can look at to compare with that uses steppermod.o ?

Thanks Tim for the reply. This morning I printed the "installemc.htm" from
your site. Havent had time to go through it fully but I'm wondering if I
can apply the ideas to setting up newer versions dated after May 2001 (the
BDI 2.2.18 release).

Vince
