1.I can’t seem to find any information about being able to implement commands m80 and m81. Being in the middle of a long print, I cannot experiment.
2.I would like to interrupt the power after a long print and have the machine totally turned off.
The Power supply I have makes a lot of noise, and in suspect for failure. I have a fan on it and have it lifted off the surface , so as much air can get to the intake diaphragm.
Some code to shut the power off while I am away from the machine would put my mind at ease.
