I have the trial version of madcam loaded. I want to use it with a 4 axis mill running under emc2. Does anyone know of a post processor the works with emc2?

Thanks

Post a snippet of the emc code and let's see what it looks like. The postprocessors in Madcam can easily be edited to make about any post you like.

I have been making progress. I have gotten Madcam to generate some gcode using the iso_g_code pp.
Nothing i can test on my machine, my simple object goes over the 200 line limit so i have to make a simpler,model.
I have 4 axis so i set about trying to add the A axis to the file. While doing that i came across this in the iso_g_code pp

*RAPID_FEED*
10000
*TOOLCHANGE_TIME*
0.3
*RAPID*
G00 "x" "y" "z"
*END_SECTION*

i looked at the fanuc pp it had this
*RAPID*
F20000
N"lnbr" G01 "x" "y" "z"
*END_SECTION*

mach3 5 axis had this
*RAPID*
G00"x""y""z""a""b"
*END_SECTION*

but no *RAPID_FEED*

what does *RAPID_FEED* do and what does "10000" represent.

the Madcam help file says this agout that
*RAPID*

Place lines for rapid movement here

*END_SECTION*

no mention of a *RAPID_FEED* section

getting this thing setup and testing all of this stuff is going to be very time consuming.
It would be nice of there was some documentation on how the PP file effects the gcode, so people don't have to reverse engineer it to be able to test for compatibility.
any hints will be greatfully received.
I am getting punchy been at this for a while today.

Mike i am not ignoring you just semi panicked about getting this thing either working or not working. If i it works i am done. If is dosent i have to go on looking for something that does.

emc is RS274 complient with the exception of a few codes that are not supported. I can't find the list of exceptions just now, and of course i cant show you a gcode example of them in action or nonaction.

when i looked at the unsupported codes i was not fearfull that i was missing something important.

I am trying to make sense of the pp files as you can see from my other post.

i am somewhat put off by the amount of testing this is going to take, crashing $50 tools into a work piece that already has 5 or 6 hours work in it is bad enough, but missing your delivery time is even worse.

cx I just sent you a pm with my ph #. Give me a call if you can.

Was a post processor ever produced for EMC2, I also need it.

Hello,

It seams like the EMC2 reads standard G-codes.
There are several post processors for G-codes included with the madCAM download and the default post processor when installing madCAM is for G-codes.

I have now created two post processors called EMC2 and EMC2_4-axis. Please let me know if there is anything that should be added or changed.
