You don't really need an oven to anneal Nylon... use your printer instead!

How to use this file:
Put a sheet of aluminum foil on your print bed
Put your nylon parts on the aluminum foil
Cover everything with a cardboard box, optionally cover the top of the box with foil too
Close the top vents on the core one
Run this gcode file
... 9 hours later, you have annealed parts!
Why make this?
I have been printing Nylon for a while and wanted to try annealing my parts for extra strength. I didn't want to use my kitchen's toaster oven, however, so I decided to try using my headed bed instead.
One issue with using the Core One to do this, though, is the heaters turn off after 30 minutes of inactivity. Additionally, prusament recommends a specific temperature ramp speed, which is a pain to run by hand.
So I generated a .gcode file that does the following:
Slowly ramp up the bed temperature, 1.5 degrees per minute, until reaching 110 degrees C
Hold the bed at that temperature for 8 hours
Slowly ramp temperature back down
Beep when done!
Note this file also sets the extruder to 100 degrees C for the entire cycle, in order to help bring up the chamber temperature. I chose 100 because it's low enough that it doesn't matter what material you have in the hotend at the time.
Note: PrusaSlicer's gcode viewer may flag this file as invalid (there are no moves) - that is expected; run it from USB or upload it via Connect.
Changelog:
1.0.0: first rev, bed ramps up, holds 8 hours, ramps down
