Ability to store fan speed?

obzocker

Is there an Ability to store the current fan speed? I want to modify the
"pause" and "resume" so that i can turn the fan off when paused and resume with the fan speed that i saved.

@obzocker Yes. You can store the fan speed value in a variable...

@obzocker
What firmware are you running?
Perhaps also post pause.g and resume.g
You can restore fan speeds , but there were changes in V3.3

Previously the command M106 R (with no P parameter and no value after R) would restore the last saved default print cooling fan speed, and if you did supply a value after R then that value was ignored. Now it is mandatory to specify a restore point number after R.
Fan speeds are no longer restored automatically when resuming a print. If you change the print cooling fan speed in pause.g, restore it in resume.g using M106 R1.

Is it possible to do that without saving fan speed? E.g. on pause set max fan speed to 0 and on resume back to 100%?

cosmowave

@zapta Yes. Set your fan to 0% at the beginning of pause.g, and back to 100% at the end of pause.g.
