K40 without air assist on MDF — watch closely. Good ventilation is essential. MDF fumes are heavy and unpleasant.

💨 Air Assist

MDF cuts consistently (no voids like plywood). 2 passes at moderate speed gives cleaner edge than 1 slow pass. Heavy fumes — ventilate well. Air assist critical. Stock K40 tube output varies; tune power up/down by 5% if edges are tacky or over-charred.

"Used it with a Glowforge — engraved beautifully with no changes. I will be purchasing more digital downloads from this shop."

"I was struggling with lining up my NFC business cards. I was able to not only line them up much better but also do multiple cards at once — making that job so much easier."

"This template made my slate coasters so much easier. 4×4 coasters from Michaels drop in easily and are easy to remove. Def worth it."
