Smootherizer

### DESCRIPTION ( Introduce yourserlf and your project)

Hello, we are Andy, Branco and Jonathan. We are 4th year electrotechnology students. This is our endproject.

We are making a machine that makes 3d printed objects smoother by heating a chemical fluid. We have our main pcb and the machine itself, but we need a second pcb to connect a little bit more IO from our microcontroller to our raspberry pi.

### TECHNICAL DETAILS (With project photos)

This is our machine almost completedly assembled. The only things missing are the PT100 and the heaters.

This is our machine from the inside. The ribbon cable connects our current pcb with the Raspberry Pi. The 2 fans in the back of the machine are for internal cooling, the fan on the side is to suck the fumes out of the enclosure where the 3d print is seated.

A close up of our pcb. The microcontroller is an ECIO40. We use an old PSU to power everything except for the RPi, which is powered by its own adapter.

### Words to PCBWay

We need a small pcb, without the components. We have the parts and can solder it ourselves. This is the pcb we need. The pcb is 2 layers, and is 86mm by 66mm.
