I have had the GF+ for less that a week as of 1/5/19. In laser cutting some 3D truss designs that I had previously cut on a band saw, I noticed a way lot of smoke coming from the GF.
So I used some window strip tape and metal tape to seal out openings around the GF. It did not work. Smoke Smoke and more Smoke. Then I decided maybe I’ll read about “leaks” on the forum. After reading some threads here it was clear that Dryer vent connections possess FLAPs to keep critters out of the venting that flap-open when an actual Clothes Dryer operates. In my set up I have two(2) flaps; one at the wall interconnect and the other at the outside port.
However, the blower motor on the GF is not as powerful as a Clothes Dryer blower; so the flaps remained partially closed and I was getting a backup into the GF that went into the room.
I removed both flaps (and intend to add a open grate at the outside port that should keep small critters out). Restarted my cutting and now no more Smoke in the room.
I need to read more!
