Electronics
This part is tricky to describe because there are so much personal choices as I mentioned in the sourcing page. There are several ways of doing this. The most commonly used set is the RAMPS system which consists of several boards. Below is description how to join these boards.You may choose to use another system without penalty just make sure the general connections are the same.
If you have some troubles please refer to the manual of the manufacturer for information or forums on the internet since we can’t support every system out there.
| Place the RAMPS board on the Arduino. |  |
| Place the jumpers on the RAMPS board. These set the stepping rate. No jumper means just the hardware steps (200 per rotation). 1 jumper makes 4x the steps, 2 jumpers make 8x steps and 3 jumpers make 16x steps. That means the original 200 steps per revolution are multiplied to 3200 steps. |  |
| Place the controllers on the print. Mind the orientation! If your controllers looks like mine than place them like in the picture. If not, refer to the manual of you controller and of the RAMPS board to see what the orientation should be. |  |
| Optionally, you can mount heat-sinks on the stepper controllers and/or a fan but didn’t need to. |
