Bulldog Lite on FABtotum

Bulldog Lite feeder on the FABtotum personal fabricator

The test is based on this setup:

FABtotum personal fabricator 1.0
FABui v0.93
FABlin 1.0.0091
Hybrid head 1.0 (j-head with 0.35 mm nozzle)

A new bowden tube is attached to the head and original bowden is still attached on original feeder.

I have made this simple adapter in order to use the Bulldog lite with the original cabling without make any modification and restore easily the original feeder.

Steps per unit in the wiring diagram are for Bulldog XL
Do not connect or disconnect the stepper motor to the TOTUMduino with the FABtotum powered on, you can burn the stepper driver SOLDERED on the board

Before start to print is necessary set the steps per unit for E axis with

M92 E96.4585

command and store it into the EPROM with the


command (this operation is valid for FABlin firmware in the FABtotum but also for Marlin firmware on a generic RepRap printer).

The sample print is sliced with Slic3r, without using retraction.

The connector used in adapter was recovered from a broken CD-ROM drive board.



Special thanks to Gianluca Faletti (aka Kino), for hints on steps per unit calculation.

Plughi RepRap 3D printer


Plughi is a 3d printer prototype based on different concepts (mostly stolen from LuzBot printers,Prusa I3, personal POV), steel and alu i3 frames are too expensive.

(Author quote from Github)

The project was started by Gianluca Faletti aka Kino, in this page i report my contributions under blog form, all the docs and contributions are stored on main wiki pages on Github.

Video editing and tools


Using mencoder to join single images into a movie, in this example multiple still images (jpeg) are joined in a single .avi video

mencoder "mf://*.jpg" -o movie.avi -fps 5 -ovc lavc -x264encopts subq=6:frameref=6:bitrate:75:meumh:bframes=1:cabac:deblock -vf scale=640:480


mencoder mf://*.jpg -mf fps=25:type=jpg -ovc x264 -x264encopts bitrate=1200:threads=2 -o outputfile.mkv

What is this site?

Mostly it is a collection of notes taken by me (Alessio Cavalieri), since I prefer to share them with the world, you never know who may serve someone else =), instead of keeping them stored somewhere.

Why itink? What does it mean?

Tinkering. The meaning is deeply rooted in my way of thinking and solving problems, you can also call it hacking or tweaking.

I tink therefore I am - tinkering in English can be translated as thinking with hands, this phrase mimics the phrase “I think, therefore I am”.

Finally, I would like to quote this sentence, this is consistent with my way of thinking:

Do not learn to hack, hack to learn! (found here)

More about the translations

I am a native Italian, the translations are made without great pretensions, I hope you won't find too many mistakes :-)
