Alright MCG I am reusing a vacuum pump that has an air pressure sensor and a mini dc pump (yb370) I originally used it to vacuum seal filament bags, and SMT pick up tool once in a while, however I wanted to make some changes to work with a foot pedal and a solenoid.

What I have got right now is a 5A pwm controller that has a resettable fuse.

air pressure sensor hp203n (reused)
arduino nano
OLED screen
lm2596 or mp1854n 12v -> 5v for motor and nano usb powered
logic level shifter for hp203n operates at 3.3v

Now my question is, how should the motor behave? Should I just have it continuously running even when air flow is block (picking up smd chip with blunt needle) or would I want the motor to stop when it reaches a certain negative pressure, and turn back on when it loses *insert epsilon value* kpa/pa?

To me it seems option 1 would wear the motor out or ruin the motor while at the same time maybe not, while option 2 also seems like it would ruin the motor and the reason for that is because the pneumatic connectors I currently have suck apparently since I cant hold a seal when suing any of them.
