that’s what I’ve done. I don’t have the MPCNC in an enclosure, the ducting is just tiewrapped to the laser (and suspended above), so the suction follows the laser around. this has robbed me of a few inches of travel. I could probably 3d print some duct/vaccuum attachment that gets smaller, but I havent needed the extra room yet. I have my air assist on the opposite side of the laser, blowing the smoke towards the duct. you can see some if this in the last few pictures I posted in my thread Quartapounds MPCNC in Toronto Area - #47 by quartapound
