I have remodnc running with our milling machine.
but I can't make a tool change.
at set N80M66
I get the error message 078.
Everything else works.
M66 is the command for the machine to change the tool

Error 78 is:

A program number or a sequence number which was specified by address P in the block which includes an M98, M99, M65 or G66 was not found.The sequence number specified by a GOTO statement was not found. Otherwise, a called program is being edited in background processing.Correct the program, or discontinue the background editing.

If you're drip feeding and you make M98 calls out to a sub routine/sub program then that sub program needs to be in CNC memory.
