Changing decimal precision on MPFAN post

[lookingforhelp1]

Hi new to this stuff. I'm designing using Solidworks, saving as a DXF file, importing the DXF into MasterCam 9, then posting using MPFAN a generic Fanuc Post. Question is.....
The output is only 4 decimal places and I would like to increase that to 8 decimal places. How would I go about doing that? Do I need to edit the Post processor?

Thanks

check mastercam to see if it is set for 5 decimal places on the cad end of things

Do you really need 8 decimal places? Are you running some sort of ultra high precision machine (like a wire E.D.M)? The reason I ask is this.............the standard tolerances for most C.N.C equipment is +/-0.0001" for positioning, and +/-0.0002" for repeatability. Those numbers are for a new machine, as it wears, it will get even more sloppy. So even if the control will take 8 places, it really won't matter, because it is way outside the resolution of most equipment. Could you tell more about what you are doing? Thanks.

first i only said 5 places lol if you look in the config. of mastercam you can adjust how many you go lookingforhelp said his posted prog. only whent to
.001 that may be in the post or it may be in the system config. of mastercam

mekdad, my mistake. I should have directed this to lookingforhelp1. I also should have asked if the output is in inches or metric. Even if it is is in metric, 8 places is still out of the resolution of most machines.

yep 8 places is a bit out there

Thanks for the responses.
In MasterCam under "screen", "config", I selected the "NC Settings Tab" and entered 8 in the "Decimal places for NCI" box. Not sure if this is the correct place to set the system defaults though. The reason I need the precision is that I am drilling small holes on a repeating pattern and the "rounding" of the numbers is causing errors in the finished part.
