Hye guys, my 3d machine ST3042 pump has got some problem lately. When I first starts the vacuum, its working fine. Everything sucked in well. After few minutes, the pressure gauge meter will slowly move from green to red zone. Thus, somehow my pump losing its power. What could possibly be the cause?
P/s: I have tried to detect if theres any possibilities on the silicon sheet leaks. Tried to put water with some soap and starts vacuum. Seems like theres no bubbles indicates any leak on the silicon sheet. If you have better ways to validate the problem, Please advice.
