Adjustment of Oozing on Dispenser 5V USB with trimmer on PCB.
Dispenser V5 has upgraded usage of power of stepper motor and as well less heat from electronics and motor due to current limitations trough the motor when no command is given to the motor.
Dispenser is operated with one hand and all controls are in your hand!
Joystick to control & turn stepper motor shaft left or right and move piston in direction chosen by joystick. Automatic is auto reverse for Oozing control. Green LED indicates motor rotation in any direction. Stepper motor has auto reverse movement to prevent continues flow of paste (or liquid,..) through the needle (oozing control). Auto reverse can be user adjusted with trimmer on PCB.
Stepper speed is additionally controlled with joystick – 5 speed and 5 LEDs to precise control dispensing. Auto reverse is in effect after each dispense to minimise oozing.

Very powerful stepper motor with full metal gears & tremendous pressure is used for SMD SMT solder paste compressing in syringe to flow through the needle and drop to PCB.
Power Supply needed is 5V DC – 0.5-1A
