Based on Prusa i3 heated build platform cable strain relief clip, this cable guide is smaller and does not exceed the bed by more than 5 mm. It also has a hole for the zip tie.

This is a simple 40 mm fan holder for Misan's Another Compact Extruder. Used with half fan mount, it cools off the J-HEAD preventing the filament from melting in the upper part of it.

Unclogging a 3D print head is not always an easy task, especially when you lack of the proper tools. They are sometimes hard to find. To unclog a .35mm J-Head fitted for 1.75 mm filament, I am using a strand of a steel cable and a stake flag. The steel cable strand is small and stiff enough to be inserted in the print head by the tip of it. Its diameter is less than .35 mm. The stake flag provides me a rod that I insert in the filament intake. It is stiff and long enough to push it down to the tip of the print head. Home Depot sells both for less than 4 dollars. !unclogging_tools The procedure to unclog the print head is:

You may experience an "Internal server error" on the home page of your site if you are a customer of iPower. You cannot access the home page nor login to WordPress. Simply edit the php.ini files located in the root directory of WordPress and in the wp-admin subdirectory to fix this issue. If they do not exist, create them. Add a line containing "cgi.force\_redirect = Off", without the double quotes. You will need to update or create these files either using iPower's file manager or FTP.

A GCode Analyzer for 3D printing is now available. This on-line tool estimates the amount of filaments required and the cost to print a 3D object. Give the filament type, customize some parameters if needed and upload the GCode files. Dual extrusion is supported. The current version is beta. Click on 3d printing GCode analyzer to give it a spin.

On most Linux distribution, it is impossible to access a serial port (ex. /dev/ttyS0) from a web server such as Apache or lighttpd using a cgi. Simply add the user under which the web server runs (www-data for example) to the group dialout. To do so, use vigr from the command line and add the user on the dialout group line. Such a line will typically look like:

The biggest issue when printing 3D ABS objects is warping. As an example, this 8 cm x 8 cm bit holder is badly warped. In this example, 5 mm. !](http://www.ctheroux.com/wp-content/uploads/2013/02/dremel-bit-holder-warpage.jpg) Adding disks (1.5 cm x 1 mm) at each corners prevents warping almost completely. These anti-warping disks can be easily added on the plater of Slic3r. The printing end result printing is shown on the picture below. 1 cm x 0.6 cm disks also works fine.
