Summary

UPDATE 2: Version 2.01
-: Added more space for side diodes
-: added fan 30 x 30mm and thicker cover

After printing version 2 i discovered that the diodes in the sides wont fit so i had to fix this .. now the fan holder plate is thicker screws fit better..
case now is at 40 x 40 ..

Update: version 2.00

After testing the first prototype, i noticed the diodes getting warm so i updated the enclosure to include a 30mm fan to cool them out !

So looking at different posts on forums i came across the stepper motor smoother ! it uses 4 to 8 diodes to silent the stepper motors ..

different boards are out there , but one can simply build it and encase everything in the case i designed !

this Little addon will eliminate those fuzzy line on your prints ...

Parts needed

1N5404 or 1n5408 diodes
12v 30 x 30 fan
2 x 4 pin sockets
piece of wires ..

Instructions

print the stl file
gather the parts and solder them as per schematic
install in case and secure with some hot glue ..
make sure you power the fan from a 12v source.

connect the smoother in series with the stepper motor - ie between the stepper motor and the stepper driver

enjoy
