Is there a feedback mechanism to tell my tool change code that G30 has completed ? Similar to ishomed ?
axis.N.homed
(bit, out)
axis.N.homing
(bit, out) TRUE if the joint is currently homing

It's a bitmask of flags.
linuxcnc.org/docs/2.7/html/remap/remap.h...i_file_configuration
64 (bit 6) is something specific to PathPilot.

I can't find any info on that "FEATURES=64". I have seen some reference to it meaning 64 bit kernel, But can't confirm that.

So I get the:
REMAP=M6 modalgroup=6 prolog=change_prolog ngc=toolchange epilog=change_epilog
in the ini file, but I don't get what to write in the toolchange.ngc file.
o<toolchange> sub
G30 # go to g30
T? # now change tool
o<toolchange> endsub [1]
M2

I would use something like
G53 G00 X0
G53 G0 Z1000
to go to the home position.
You don't need to do anything with T in the G-code sub
The prolog code will have populate the parameters #<tool> and #<pocket> for you to use.
An example toolchange.ngc is here, though it is a rather fancy one that allows extra wear offsets:
github.com/LinuxCNC/linuxcnc/blob/master...anucy/toolchange.ngc
G53 G00 X0
G53 G0 Z1000
to go to the home position.

Thanks' Andy
So in the .ini file I put :
REMAP = T prolog=get_T_number ngc=toolchange
I made a file called toolchange.ngc with this code:
O<toolchange> sub
#<tool> = [#<tool> MOD 100]
G53 G00 X0
G53 G0 Z1000
M6 T#<tool>
O<toolchange> endsub [0]
And in remap.py I added this code and compiled it to remap.pyc :
from stdglue import *
# Extract the T number into a parameter, but don't try anything else clever
def get_T_number(self,**words):
try:
cblock = self.blocks[self.remap_level]
if not cblock.t_flag:
self.set_errormsg("T requires a tool number")
return INTERP_ERROR
self.params["tool"] = cblock.t_number
return INTERP_OK
except Exception, e:
self.set_errormsg("T%d/prepare_prolog: %s" % (int(words), e))
return INTERP_ERROR
Everything fires up ok ,but when i call a tool chnge ,say "M6 T01" I get:
pycall(remap.get_T_number)failed
Thanks'

Where is the remap.py file? (there is actually no need to compile the .py file, it will get auto-compiled as needed)
Try making the SUBROUTINE path match the sample file:
github.com/LinuxCNC/linuxcnc/blob/master...lathe-fanucy.ini#L27
And put the remap,py and toplevel,py in the same folder as the INI.

Andy,
I believe the files are in the right place ,what does this line do? I don't have it in mine and I see it references the "python-stdglue" like your remap file does.
github.com/LinuxCNC/linuxcnc/blob/master...athe-fanucy.ini#L104
Thanks'
Brian

Hi brianTruck
Could you post your Hal and Ini files?
I am working on converting a Boxford 125 to pathpilot and are struggeling with many of the problems you seem to have solved.

Here are my current files , m6 remap is commented out because it still is not working right. I will be working on getting spindle speed input next.
