Hi everybody. I'm having some issues with the CAM module (again ). I make a program to use in a postprocessor MACH 3 (G54) but in the text file appears an error; several lines ends with dots, and when i put the program on mi CNC, every time that it comes to that point, it stops. It is very annoying, and i can't find a solution.
I attacht the file, for everyone to see.
I tried with others postprocessors but is the same.
Apparently, it stops when it reaches the number Z7.
Hi Theo,
I'm not sure what machine or control you are running this program in... Could the problem be that all the decimals need trailing zero's?? If this is the case you need to edit your post processor to post the trailing zero's instead of omitting them.
I am using a CNC 6040 and think the machine is having problems with trailing zeros. I will try a couple things and give my feedback. The thing is that i'm trying to see what the limitations are with this module. The first thing i tought was to change a parameter in SW to generate the program with one decimal, but i could not find that option. I had to edit it manually, and in a long program it is pretty heavy work.
Hi Theo,
Please check the value in your Tool Length Height offset H14. It should be the measured length of your tool.
Hi Theo,
You can send me your post processor and I'll fix it for free.
But this is clearly these two lines you need to edit
Open the *.SRC file for the post in notepad and find these two lines in the top of the document:
:INT_LEADING=FALSE
:INT_TRAILING=FALSE
Change them into this:
:INT_LEADING=TRUE
:INT_TRAILING=TRUE
Remember to compile source again and put the new ctl file into the post library.
Thanks for the answer Tim! I'm a little bit lost. Wich file should i modify? The one you are saying *.SRC, i can't find it. I'm not understanding if you are writing about a SW18 file, or a MACH 3 software file. Can you enlighten me?
Actually - you have Z0 on bottom of part and then I can reproduce.
You need to change this then:
From:
:SYSTEM=MILL
:LEADING=FALSE
:TRAILING=FALSE
:DECIMAL=TRUE
:QUAD=NO181
:SPACE=TRUE
:ARCS=RADIAL
:METRIC_SHIFT=1
:G_LEFT_PLACES=3
:G_RIGHT_PLACES=3
:G_INT_LEFT_PLACES=3
To:
:SYSTEM=MILL
:LEADING=FALSE
:TRAILING=TRUE
:DECIMAL=TRUE
:QUAD=NO181
:SPACE=TRUE
:ARCS=RADIAL
:METRIC_SHIFT=1
:G_LEFT_PLACES=3
:G_RIGHT_PLACES=3
:G_INT_LEFT_PLACES=2
The :G_INT_LEFT_PLACES=2 is how many decimals you need - so maybe you need 3
Compile, copy CTL, select the post processor again to ensure it is in use - post.
Hi Theo,
What machine is this for?
Also I do not see the error, whats the number line it stops at?
