Program stops at G53

It isn't actually stopping at the G53 line, it is stopped waiting for the tool change on the next line. Your machine must not have tool changing configured correctly. If you'd load T1 manually from the MDI, I bet the file would run fine.

Your choices are remove the tool change commands from the G-code, or fix the tool change part of your Linuxcnc config, (by properly enabling manual tool changes, or ...)

If I MDI a tool change, T1 M6, I get the same results if I delete the tool change line it works successfully, I do not have a tool changer, Bridgeport style mill.
Where do I find hal_manualtoolchange and what do I change so I can do a manual tool change with multiple tools?

Thank you,

hopefully this helps:
linuxcnc.org/docs/2.7/html/man/man1/hal_manualtoolchange.1.html

I think all of the sample configs use it aside from qtvcp, so there are those examples too.

Added this to the end of the .hal file and all works well now.
