In case something goes wrong, plug the PSU into a power strip with an on/off button. Once the wires connected to the PSU, make sure none of your computers is doing something important (like a system upgrade).

Make sure you use a Regulated Power Supply, make sure you connect the ground wire for the mains to the power supply, and if it has a fan, make sure it has sufficient space around it to let air flow and cool it appropriately. However, be careful that with a 24V PSU, you will need 24V fans, and will need to reduce the PWM setting for your heating elements. This is the reason some designers use 24V PSUs. However, the higher the voltage, the more you will get out of your stepper motors. 12V PSUs are more common, and generally cheaper. While most of the components on the Smoothieboard are rated up to 32V, it is not recommended or supported to use that voltage.

#Cambam load 3d how to
How to choose a power supply unit (PSU) : The board uses power to move stepper motors, and power heating elements, fans, and others. Without power, your board can not do much. You can not learn by making mistakes here, as mistakes will likely cost you your board.Įlectrostatic discharge can also destroy your board : make sure you properly ground everything.įor a good read about safety, you can refer to the RepRap Wiki documentation on the subject The general idea here is: always make sure everything is clean, and double-check everything before turning the power on.

Like the 5V line, or an end-stop or thermistor input for example.
