Adjusts current setting potentiometers on stepper drivers
Long lasting, good quality ceramic tip
These are for adjusting those little current setting potentiometers on stepper drivers. The non-conducting tip means that accidentally poking other components, pins, or traces won't damage or interfere with the stepper driver. Using metal tipped screwdrivers while the driver is powered on can cause damage to the driver or even the controller board. Additionally using a metal tipped driver often introduces electrical noise during the adjustment as the metal driver acts as a small antenna making precise adjustment hard.
Item Specifics 1 - Ceramic Driver Should not be used as a general purpose screwdriver Not Recommended for applying larger torques
