I purchased a 3018 CNC 2 in 1 router laser machine. LinkLink
I’m a newbie and is still learning. I am trying to make stuff from 4mm MDF.
I’m using the following settings:
Power 100% (7w)
Speed 200mm per second.
Number of passes 50.
The laser does a very neat cut, but it still does not cut through the 4mm MDF.
OK, well my next question would be “do you have air assist” but that’s been asked & answered already.
You will likely find that good strong air assist makes a world of difference when cutting.
Diode lasers and cutting are just not a good combination. And I’m speaking as someone with a 5.5W diode laser bolted to my CNC. I just used a Loc-Line hose zip-tied to my laser for air assist, connected to my compressor. Works well for keeping the path clear.
Use the laser to engrave. Use the CNC to cut. Use the right tool for the job.
I have had no issue with my 7w output blue LED laser when cutting 3mm balsa or similar wood. Not sure what the difference with 3mm MDF other than probably various wood type and the glue. I cut this with 2 passes at 80%. (It is on a 3018 PRO also)
