Are you using a Loc Line hose with the compressor? Mind sharing what parts you use?
Now I’m thinking if I’m going to invest in an aluminum bed, might as well use my X-Carve for two functions
- Mist or flood for aluminum (Probably something like you have if it is indeed sufficient for keeping the end mill cool)
- Drainable fully submerged for carbon fiber
My X-Carve is in a soundproof box, so it would be really easy to use 1/8" HDPE sheets and silicone caulk to waterproof it.
I’ve had a similar experience with Kodiaks. Work wonderfully for an hour, then okay at lower depth per pass for 5 hours, then they too dull to use.
