Little update, I have been doing not as many cuts recently, selling junk on ebay to buy the new air blast system. I wish I could go with a mister with some coolant, but my bed being particle board, aka a sponge, I would like to keep it dry. Picture is one of the motor mounts, before the width of the cut exceeded the stock and hell broke lose. My fault entirely, need more stock asap! Buying stock online bugs me knowing that I am paying an extra 35% just to ship it to me.
Squared everything all over again and my results are coming out fantastic. Once I get the air blast, I have full confidence in the mpcnc. As of now I have to follow the bit at all times with the shop vac or the chips build up in the slots really quick. It’s kind of cool, the chips form a fuzzy texture in a pile. They’re really nice chips though, like a small version of the ones you see in those youtube machining compilations.
To anyone else trying aluminum, always CLIMB mill! On the finish and on roughing. Conventional isn’t better at doing anything. The only time it doesn’t matter is during slotting.
