Hey all,

First time poster but long time reader! Have just gotten my new Laser Master 3 but still to fire it up as builing my set up. Lm3 has a 10w laser midule and gave air assist by way of the external Ortur compressor.

I’m wanting to cut a slit in 12mm MDF to use as part of my waste board. Technically doesnt need to be a cut out but does need to be at least 6mm deep. Slit will be 3mm wide.

I’m not 100% sure the laser will cut through it but wondering what anyone’s thought were on engraving the slit? Or best to cut the whole slit out (if ot can)?

Cheers,

Steph

      "cut a slit in 12mm MDF"
Rather than vaporize all that MDF, slice the board with a saw, then glue the two pieces together with a strip of of 3 mm MDF standing on edge at the bottom to form the slot. Cut the strip to whatever width makes the slot the proper depth.

This depends on being able to saw-cut straight paths, a trick I generally got right using a radial-arm saw, Doing it by hand poses a definite challenge.
