This potentiometer can be turned with a small screwdriver. The reference voltage, or VREF, can be measured with a multimeter from the metal potentiometer top, to a ground point on the motherboard.

The maximum VREF that a stepper driver is rated for, is typically determined when using a heatsink that is cooled by a fan. In the JGAurora A5 and A3S, there is no internal active cooling inside the main chassis, so care must be taken to avoid the drivers overheating. When stepper drivers overheat, they are not usually damaged, but they will auto-shut down until their temperature drops back down to a suitable working level. Different models of stepper driver, have different maximum current ratings.

To work out the current output, each stepper driver also has a specific formula that allows the output current to be calculated from the reference voltage.

Make sure you are using the VREF suggestions for your specific type of stepper driver! The voltages below are recommended for stock A stepper drivers only and are calculated with the formula below:. Plug and play. Once the firmware is burned in the flash memory of the 3D printer, whenever a user plugs it into a Windows 10 machine, the standard driver will automatically be downloaded and will use the custom print capabilities that the developer has chosen.

For more information, see Microsoft OS Descriptors. To specify to the Windows operating system that we are currently using a 3D printer, we have to use the right compatible ID. With this specific configuration, IHVs can compile their firmware and flash the device.

Then when the device is plugged in, the 3D Print Standard Driver will automatically get downloaded from Windows Update. This list is regularly populated with new configuration as new 3D printers emerge on the market.

As stated in the above section, IHVs have access to several base configurations. This has the advantage of minimizing the amount of information that has to be stored in the printer's flash memory. Developers can inspect the base configurations made available and choose the one that is the closest to their printers.

The print driver provided in the 3D printing SDK is an experimental 3D printer device driver still under development. If the 3D printer is experimental or in development, follow the steps in Install the driver manually section below to print to an existing COM port or print G-Code to file. This option should only be used temporarily and for development purposes. Plug in the USB serial device. Expand Print Servers , expand the name of your machine, right-click on Drivers , then select Add Driver….
