I'm a relative new comer to laser cutting, so I'm sorry if this is a basic question, but does anyone else have problems cutting all the way through MDF?
I've been trying to cut some 3mm MDF that I bought at Bunnings, but I just can't get the laser to cut through the last millimetre of the wood.
I initially set the Emblazer to 10mm/sec at 100% and 10 passes, and it almost totally cut through the mdf, but not quite. I could see a faint burn mark on the bottom side of the wood, but the laser hadn't made it through.
I then set the machine to 20 passes, but it gave me the same result. I kept adding passes, but no matter how many I added, it wouldn't punch through the other side of the wood. The wood was completely cut, but the papery laminate on the flip side seemed to be untouched.
I then slowed it down, to 5mm/sec at 100% and 10 passes, and the same occurred. To test it, I pushed it to 30 passes, which singed the edges a lot, but the result was the same. I was able to push the cut piece through, but it ended up with a rough, torn edge on that last millimetre, which is obviously undesirable.
That last sceric of wood seems indestructible. Is this a quality of mdf? Or is there a work around?
I'd love to know if anyone has any advice on the best way to cut MDF?
