# **PD Stepper** - Getting Started
|
||||
If you just received your PD Stepper this will show you how to spin a motor and configure the driver using the firmware pre-installed on the board.
|
||||
|
||||
## Connect Your Stepper Motor ##
|
||||
## Assembling a kit onto a Nema 17 ##
|
||||
|
||||
Timestamp 1:50 of [this video](https://youtu.be/qECEGUZE04s?t=110) shows how to setup a Nema 17 with your kit. There are 2 looms provided in the kit for different motors, try one and if at the next step your motor stutters/doesnt spin, power off the board and try the other one.
|
||||
Timestamp 1:50 of [this video](https://youtu.be/qECEGUZE04s?t=110) also shows how to setup a Nema 17 with your kit.
|
||||
|
||||
NOTES:
|
||||
1. Do not disconnect/connect the motor while the board is powered.
|
||||
2. If you are not using the heatspreader/spacer (partial kit) ensure the board is not resting directly on the motor as this could short out the traces on the underside of the PCB. Use washers or an insualting layer.
|
||||
### 1. Install the magnet onto your motor (only needed for reading encoder position)
|
||||
|
||||
Carefully superglue the included diametrically magnitised magnet onto the centre of the motor shaft.
|
||||
|
||||
Only a very small amount of glue is required, take care not to get any in the motor bearing.

|

|
||||
### 2. Remove the original motor screws

|
||||
|
||||
### 3. Peel off the protective film and add one of the included heat pads onto the heat spreader
|
||||
|
||||
Ensure this is added on the recessed side of the heat spreader
|
||||

|
||||
|
||||
### 4. Place the spacer onto the motor ensuring it is in the orinentaion show
|
||||
|
||||
Note. If you are not using the heatspreader/spacer (partial kit) ensure the board is not resting directly on the motor as this could short out the traces on the underside of the PCB. Use washers or an insualting layer.

|
||||
|
||||
### 5. Add the PCB
|
||||
|
||||
Again ensure the PCB is installed in the orientation shown so the motor connectors as well as the heat pad line up
|
||||

|
||||
|
||||
### 5. Add the cover and new countersunk screws
|
||||
|
||||
The included screws are best suited for a 34mm length Nema 17 you may need longer or shorter ones depending on your motor. (included ones are M3x40mm)

|
||||
|
||||
### 6. Add the heatsink
|
||||
|
||||
Use the larger heatsink if you plan on running the motor for long periods and/or at high currents
|
||||

|
||||
|
||||
### 7. Plug in motor loom
|
||||
|
||||
There are 2 looms provided in the kit for different motors, try one and if at the next step your motor stutters/doesnt spin, power off the board and try the other one.
|
||||
|
||||
Note. Do not disconnect/connect the motor while the board is powered.

## Running the Webserver ##
|
||||
**1.** Connect the PD Stepper to your PD power supply.

|
||||
**6.** For your own projects this code as well as others (such as ESPHome config) can be found [HERE](/Software)
|
||||
|
||||
**7.** The buttons on the side can also be used to change the velocity
|
||||
|
||||
## Trouble Shooting ##
|
||||
- The motor will not spin unless the board is receiving correct the voltage requested from the PD Source. So ensure your brick can supply the correct voltage. The requested voltage can be adjusted on the fly in the webserver.
