Solidcam to EMC2 post processor

Hi All.
I searched Linuxcnc.org for working post processor from SolidCam to EMC, and did not found any.
So I changed existing FANUC (for Mill) and FANUC0T (for Lathe) in SolidCam.
It worked for me in SolidCam 2008SP12 and SolidCam2009 SP0. I am using EMC2.2

To use modified post processor extract attached archive (which includes both post processors) to C:\Program Files\SolidCAM2009\Gpptool , choose to override existing files (you can backup existing files just to be safe).

This is my first post in this forum, so if I made any mistakes I want to apologize in advance.

Thanks for sharing.

Can you please explain what changes are necessary? I'm trying to make a postprozessor for Unigraphics NX6 perhaps this could help me.

hi Axel

there is not alot to edit if you have a good standard fanuc post, just check your cycles, and G80 line on end of cycles like drilling, as fanuc can take G80 Zxx EMC likes G80 G00 Zxx

cutter comp drive lines is also worth a check.

Lathe wise there are not many cycles there so most of it just system output code
should not take long if you have a good starting ground and know how to edit a post.

This post processor seems to work alright for me with Solidcam and EMC2. Although, I tried performing a Transformation->Translate->Matrix, which uses WHILE loops. When I tried to load the code, EMC2 didn't recognize the structure of the WHILE loop and gave me an invalid character error. I'm pretty sure that the post processor needs to be modified but I'm not sure how. My generated code looks like this... Any help would be greatly appreciated.

Also, the section of the post processor that I think needs to be modified is shown below.

@loop
local integer var_num

var_num = loop_level + 20
{nb, '#', var_num, ' = 0'}
{nb, ' WHILE [#', var_num, ' LT ', loop_count, '] DO ', loop_level}
endp

;

@end_loop
local integer var_num

var_num = loop_level + 20
{nb '#', var_num, ' = #', var_num, ' + 1'}
{nb 'G'home_number}
{nb ' END ', loop_level}
endp

;
