….but this component pretty much completes the laser cutting system. Its the motor speed control for the ventilation. I can now draw off all the fumes and oxygen generated when the laser is cutting.

Basically, the system is now fully functional.

This thing is pretty much ready to run. I’ve installed two tubes for drawing away fumes. One is attached to a plexiglas hood that sits around the cutting head, the other runs below the table. The blast gate on the lower tube helps regulate the draw in comparison to the top hood. Both tubes combine in the wall behind the back of the table, and the larger 12 inch tube runs up to the ventilation fan. The fan is wired up but what remains is to get a motor speed control, and put a hole through the roof with a roof cap.

Another pic of the table.
