This hack keeps the Solidoodle extruder head from wobbling when making rapid Y-Axis movements. It moves the lower teflon retainer block on the X-Axis carriage to a spring loaded arm that keeps the back of the print head from bouncing up. This also keeps prints from being distorted when printing near the back of the print bed, where force from the cable assembly can sometimes tip the print/extruder head.


1) Print the piece

2) Unscrew the lower teflon retainer block underneath the rear X-Axis support rod.

3) Insert the retainer block into the printed piece, securing it with a suitable screw and nut.

4) Insert the whole assumbly into the old retainer's block mount

5) add a small spring between the spring mounting tab on the printed part and one of the rear extruder fan mounting screws

Has anyone had luck slicing this with slic3r? I'm using 0.9.8 and I cannot get any holes in the thing.

i have to add, i had this same problem with slic3r IN repetier host, but slic3r on its own made a perfect gcode.

I have a fixed version that I am uploading now. The STL came up very broken.

Lately I have noticed a bit of a rattling noise. I think this will come in handy. If I just press down a little on the fan it sounds much better. This will certainly save me the time and effort of having to sit here with my finger on the fan. Seriously though, anything to improve my prints is greatly welcomed and much appreciated.

The spring is about 1" long unsprung and very light. I'd guess it puts out about an ounce of force

Do you know what length and force the spring you are using is?
