It’s a bird, it’s a plane, it’s a CURING OVEN?

[Stroonzo (Jeff)]

My impeller is installed exterior to the shop.

Info / pictures here:

I made some modifications to the fume extraction port

So as far as fume extraction goes, I can confidently say I have a highly effective setup: Air intake plenum Fresh air supply Externally mounted impeller 6” flexible PVC ducting Effectively sealed laser machine Automated Intake and exhaust blast gates The PVC ducting creates far less turbulence, is reliably sealed throughout, is much more durable, and does not crimp or get crushed. However, as much as I prefer the flexible PVC ducting over the foil garbage, I use it against my better judgemen…

Air pump recommendations appreciated?

I’m not sure what you’re asking about specifically, so I’ll guess from the picture you referenced. The blast gates and the actuators were purchased from amazon.

Here it is drawn in LightBurn. I have a lot more to mine (controlling blast gates as well as a master line switch), but this is the relevant schematic for you (including a manual override switch allowing for independent operation of the fume extractor and bypassing the necessity for the controller signalling). [image] If you want to download the LightBurn drawing, I have attached it as well. You may want to enable Filled Smooth to view it (Alt+Shift+W). AutoExtractor.lbrn (1.5 MB)

@thx

you don’t need to seal every little hole, seam, and gap which can be frustrating

Sealing the machine (for me) is to prevent sucking the heated or cooled air from the building.
