Fanuc-Style Toolchange

Hi Rick
Thank you for your help.
I assume that I need to to more than what I just tried. I copied the attached file toolchange.ngc to my nc_files directory and added the line
REMAP = T prolog=get_T_number ngc=toolchange
to my [RS274NGC] section of the ini file
I also added tools 10001 - 10008 to my tool offset data in linuxcnc.
I get the message " pycall(remap.get_T_number) failed " when I enter t0101 in mdi.
I am sure that I need to do more than what I have done. I'm pretty new to setting up Linuxcnc, do I need to add some python code somewhare?
I have never done anything with that type of code and I am sure that I need a complete walk through with the process.
I would also like to add ngc files and the remaps that have G code "GO A0" when I call tool 1 and " G0 A 45." when I call tool 2 ect, up to tool 8?

The REMAP line says that the "T" word should now run a python routine called "get_T_number" before running the ngc subroutine.

The get_T_number routine is inside the remap.py file, and that file is linked into LinuxCNC by toplevel.py

You need to add both these files to your config folder. You will find them in the sim configs folder, or you can get them from the git links (right-click the file-name at the end of the path near the top and select save-as)

Hi Andy,
I'm also having trouble setting up this T toolchange. I've got remap.py and toplevel.py in my config folder but when I run gmocappy I get an error file not open. I've remapped M6 as well and I'm wondering if they're conflicting with each other.  Any ideas to troubleshoot?   Thanks for all your help on everything known to linuxcnc.

Hello All,
I've been struggling with using T for toolchange for a while now and I need a little help.  I've got a turret that is written as an A axis and I remapped m6 to get the correct tool in position. I've attached that toolchange.ngc  It's cludgy but it works.  If I try to remap T with the "index_lathe_tool_with_wear" from standardglue the T only causes a virtual toolchange but it won't call the M6 and physically change the tool.  Here's my ini snippet for RS274NGC
RS274NGC]
SUBROUTINE_PATH = ./macros/,./:../
PARAMETER_FILE = linuxcnc.var
RS274NGC_STARTUP_CODE = G7 G18 G20 G90 G94 G0 S500 F60
REMAP=T  python=index_lathe_tool_with_wear ngc=Ttotool
REMAP= M6 modalgroup=6 prolog=change_prolog ngc=toolchange epilog=change_epilog
Do I need to write a python script that translates my current ngc toolchange into the standardglue? 
What am I missing here?  Thanks in advance!



 

This might not be the reason for your issue but this seems wrong:

Did you maybe mean something like this instead:

[edit]
If you start your config from a terminal ($ linuxcnc) are you getting any error messages when calling your remap?

You're correct you can't call a python and ngc on the same remap line, that was my mistake
in the stdglue.py I was thinking that maybe I could change the line ~481 in the index_lathe_tool_with_wear section from: mccanon.CHANGE_TOOL(self.selected_pocket)
to: self.execute("M6 T%d"% (tool))
Where do I find documentation on the syntax of that python line? Also is this even a good idea to change the stdglue or should I be writing my own python script?
