"""
This page is in the table of contents.
Some filaments warp too much and to prevent this you have to print the object in a temperature regulated chamber or on a temperature regulated bed. The chamber tool allows you to control the bed and chamber temperature.
The chamber manual page is at:
http://www.bitsfrombytes.com/wiki/index.php?title=Skeinforge_Chamber
==Operation==
The default 'Activate Chamber' checkbox is on. When it is on, the functions described below will work, when it is off, the functions will not be called.
==Settings==
===Bed Temperature===
Default is 60C.
Defines the print_bed temperature in Celcius by adding an M115 command.
===Chamber Temperature===
Default is 30C.
Defines the chamber temperature in Celcius by adding an M116 command.
===Holding Force===
Default is zero.
Defines the holding force of a mechanism, like a vacuum table or electromagnet, to hold the bed surface or object, by adding an M117 command.

==Examples==
The following examples chamber the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and chamber.py.
> python chamber.py
This brings up the chamber dialog.
> python chamber.py Screw Holder Bottom.stl
The chamber tool is parsing the file:
Screw Holder Bottom.stl
..
The chamber tool has created the file:
