maybe in setup (in printer.cpp) the initialization of the output pin for send one did not happen due to a similar #if test. Then it would not send any signals.

Next steps, how do I remove them easily? Can I just remove all the code between "#if LANGUAGE_CHOICE == (x)" and "#endif" and reflash that new firmware, can I delete the languages
