This page is in the table of contents.
Some filaments contract 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 and the holding pressure.  The gcodes are also described at:
http://reprap.org/wiki/Mendel_User_Manual:_RepRapGCodes

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 M140 command.

===Chamber Temperature===
Default is 30C.

Defines the chamber temperature in Celcius by adding an M141 command.

===Holding Force===
Default is zero.

Defines the holding pressure of a mechanism, like a vacuum table or electromagnet, to hold the bed surface or object, by adding an M142 command.  The holding pressure is in bar. For hardware which only has on/off holding, when the holding pressure is zero, turn off holding, when the holding pressure is greater than zero, turn on holding.

===Kulitorum===
Kulitorum has made a heated bed.  It is a 5mm Alu sheet with a pattern laid out in kapton tape.  The wire is a 0.6mm2 Konstantin wire and it's held in place by small pieces of kapton tape.  The description and picture is at:

==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:
Screw Holder Bottom_chamber.gcode


> python
Python 2.5.1 (r251:54863, Sep 22 2007, 01:43:31)
[GCC 4.2.1 (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import chamber
>>> chamber.main()
This brings up the chamber dialog.


>>> chamber.writeOutput('Screw Holder Bottom.stl')
