Ok,  I'm just getting into this stuff, and I have an obviously easy/stupid question.  I want to do a very simple manual tool change. In M6Start.m1s, it just raises the Z up and does a M00 to stop so the tool can be changed.  But I want to enable the tool change LED to warn me it's time to change tools.  Is that even possible?  I've been searching for the past hour or 2, but haven't found anything that references that LED.

Thanks!

In general Config, try setting the tool change option  (Top Left Corner) to "Stop Spindle, Wait for Cycle Start".

You shouldn't need to use the M00.
