Extruder Motor Controller Board
Build It
- You'll need a soldering toolkit to do most of this.
- Read our Electronics Fabrication Guide if you're new.
This board extends from the Universal Controller Board. Build that first. After that there is a little bit more work left to make it into an extruder controller.
| Component | Value | Quantity | What is it | Mouser # |
| P3 | 2 pins | 1 | connector to sync the boards | |
| R2 | 10K | 1 | Resistor | 291-10K-RC |
| R? | 220 | ? | Resistor | 291-220-RC |
| R? | 180 | 1 | Resistor | 291-180-RC |
| R? | 560 | 1 | Resistor | 291-560-RC |
| C2 | 1uF | 1 | ElectrolyticCapacitor | UVR1E101MED |
| U? | TIP110 | 3 | Darlington | 511-TIP110 |
Next, you'll need to program the PIC microcontroller with its specific firmware. We have a guide on how to do this. You need two of these boards - one for each extruder you build. Label them E1 & E2 with a label, typewriter correction fluid, or a felt-tipped pen so you don't forget which will be which.
You can download the latest HEX file to put into the extruder's PIC chip from http://sourceforge.net/project/showfiles.php?group_id=159590
