Door Interlock?
Posted: Mon Nov 13, 2017 10:17 am
Hi All,
I have an issue in that workspace users keep opening the laser cutter door before the smoke has been evacuated. It stinks and I'm concerned about the long term health effects.
Is there any way to fit these machines with an interlock? I'm sort of shying away from the idea of having the door lock closed in case there's a fire, but maybe a simple circuit that sounds a buzzer if the door is opened less than 15 seconds after the machine has stopped? I'm not always nearby to see it happen so re-educating those responsible is often impossible..
Has anyone done this? Does anyone know if there's any way of detecting when the machine stops running? A pin on the controller board, maybe?
