Filament cleaner for Velleman K8200 3D printer

People on different forums reported problems with clogged nozzle. One of the reasons may be a dust, powder or some other contamination on the filament.

I have thought, it would be nice to have a little cleaner before the extruder…
I designed it in the way that it can be easily mounted on the frame using one of my clips (FULL or FLAT) and 2 pins.

It can be moved left or right along the frame or rotated to put it in optimal position for the filament to go through.

I cut a small piece of a kitchen sponge – it does the job.

The only thing worth of considerations is that the material used to clean the filament is soft when it is dry as it needs to hold the filament tight – some of the sponges are rock hard when dry (will not surround the filament snugly enough) and get softer only when wet.

Controller board mount for Velleman K8200 3D printer

Today I decided to change the way how the main controller board is mounted.

By default is just hanging on the frame and waiting to be shorted by the aluminium profile underneath. It is not mounted securely (only one edge of the board, 2 small screws in plastic mountings).

I have used jodbe’s design on Thingiverse (http://www.thingiverse.com/thing:193965). It has really smart solution to hold all the wires – it has built in canals so the wires are not sticking out anymore and the unit becomes very flat.

I have just modified it slightly by removing fan’s mounting points, cutting away side of the board and adding 2 mounting points for my frame clips. Depends on the location on the frame, FULL or FLAT clip may be used.

This is my design:

And this is the print out:

Then I have labelled all the connectors (X-Y-Z axis, Extruder, X-Y-Z end stops, Fan, 2 heaters and 2 temperature sensors:

In the next step I have removed the board completely and mounted it on the printed base:

Then I have added 2 of my previously designed clips and mounted the base on the printer’s frame:

After routing all the wires and connecting all the connectors I have ended up with this:
