Subject: Manual Toolchange
I'm trying to implement manual toolchange. On M6 the machine will move to a fix location and pause. Allow the user to change tools. It then run a tool touch-off routine written in C and then the user will hit Execute again to continue the code with the new tool.

The problem is I have to manually put an M0 right after every M6 to have the machine pause. I can not issue an M code from my C program to have it pause. Is there a bug or is it not implemented? I also can not "Hault" the GCode from my C program without it rewinding several GCode lines back. It does not Hault right at M6 command.

Hi Kevin,
 
I would have to look into that.  Trying to do a M0 probably won't work.  To have Gcode -> calling an MCode -> calling a C Program -> calling Gcode causes the Interpreter to re-enter itself which it probably doesn't handle correctly.
 
Would throwing up a message box ("OK to Continue?") work for you? 
 
Regards
TK

I would handle all this by modifying the post of your cad/cam .
at up to the M0,
then if you call your touchoff "C" with commands to jog the Z down until
bit "N" changes state ,then exit back to kmotion cnc

Tom;
does that make any sense?

Hi,
This is very interesting subject as I am about to go this way in my milling machine. Looking forward to learn what kind of solutions can be done.
Cheers
Bengt
