Need Help!- Mastercam to Mach3 Turn Post Processor

[Jrodbp]

Hello All,

I have a Wabeco lathe with a Mach3 Turn controller. I'm trying to generate the gcode in Mastercam X4, but the post processor file that I have in not generating the proper code for my machine. Does anyone have a post processor for Mastercam to Mach3 Turn, or would someone be able to write one for me? Please help!

This one is for X5. If it does not work, you can probably use it as a template for making one for X4.

Here is one for 9. Same thing.

Thanks, that seems to work. Any idea how to get Mastercam to output a G32 instead of a G76? I've already tried changing the thread parameters to longhand. With it set to longhand it just produces this:

N980 T0707
N990 G97 S600 M3
N1000 G0 X.2875 Z1.2091 M9
N1010 M9
N1020 T0700
N1030 M30

Any Ideas?

What did you set in parameters for number of cuts, etc.? I just did a sample file and used the longhand option and got:

G99 G32 Z-1. E.07692
G0 X.7
Z.2209
X.4811
G32 Z-1. E.07692
G0 X.7
Z.2183
X.4717
G32 Z-1. E.07692
G0 X.7
Z.2157

If your parameters for cutting are correct, then there is something in the post-processor that will not allow the G32 longhand option to be output correctly.

I looked at the post processor file but I'm not sure what I'm looking for. I did another test and I’m still getting the same results.

N1180 T0707
N1190 G97 S600 M3
N1200 G0 X.2875 Z1.2211 M9
N1210 M9
N1220 T0700
N1230 M30

You did not say which of the posts you used. I have MasterCAM X3 and used the post for X5 and got the following G-code:

N100 X.35 Z.0578
N110 X.2454
N120 G99 G32 Z-1. F.0769
N130 G0 X.35
N140 Z.0552
N150 X.2408
N160 G32 Z-1. F.07692
N170 G0 X.35
N180 Z.0527
N190 X.2361
N200 G32 Z-1. F.07692
N210 G0 X.35
N220 Z.0501

No idea why you are having difficulties.

I used the X5 post with version X4. I guess I'll just have to play with all the setting to see what works. Time for trial and error. Thanks for all the help Tx.

I do not know what you were using for your base machine. I think I used the default lathe and control and added the Mach 3 post for MasterCAM X5 for the post processor.

I changed the machine to default and problem solved.

Good deal. Happy machining.
