PLease help - gcode newbie

[scotty1]

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

can someone please look at the gcode for me and see if I have missed something, i am using a connect 121 lathe with mach3 turn

Hi,

Not experienced on lathes. Are you saying that tool 2 is moving to the wrong position? "...right through and does not start at the bar..."

If so, I notice that you have G40 and G49 after the T0202 - don't those codes cancel cutter compensation (as they do on a mill)? This would put your tool in the wrong position.

(Tool 1 may be working correctly, if you have left its offsets as zero and set your origin using Tool 1 as a reference tool.)
