I have joined 2 gcode programs together, both run seperately okay, I have the pause and tool change in the middle of the gcode T0202 see below

The 1st programs runs and takes 2 mill off diameter, it then pauses I change the tool to start click cycle start to continue. but when the tool starts up it goes right through and does not start at bar

thanks in advance
scotty

Not too sure what you are trying to do, but it appears to be going back and forth in the X direction only and at different depths. The later section appears to go over what has already been cut!

Peter

Just reread your post it appears to be lathe instructions!
It still looks at it is going over the same area and waouldnt do anything on the second set of instructions.

Peter

where are your zero coords? If I read this right it traverses Z for 3 stepping X down from 1.385 to 1.325 in 0.02 steps then a final cut at 1.32, then is supposed to peck a groove at Z-.5 to Z-.7 going in the first cut at 1.287 then in steps of 0.02 down to 1.087 with a final cut at 1.077. But this relies on the tooltip after the tool change being exactly where the program thought it was on the first part... how are you setting the tool depth on the change and zero'ing off?

HI irving, I am manually having to jog the tool away from the stock in order to change for the larger tool, I can roughly understand now, I will change my home position to further away from the stock to enable me to change tools.

thanks again
