CNC Laser - Getting Close
So, As I've mentioned in some other threads, I think I'm starting to get close to getting the laser etching thing working.
This is an example of an image that I'm thinking is not really all that well suited to it. The more I play with this, the more I realize that there are some variables that need to be thought about.
1) The image and the contrast
2) The amps going into the laser
3) The max value and min value you need to set in the software that creates the gcode
4) The material you are burning it on. Every piece of wood seems to react differently.
5) The distance from the diode to the workpiece
5) Make sure you focus the beam before you even think about starting a test.
But, I think I'm getting close.
I think I need to find a better 'target' for burning. I've tried cherry ply, this is just some cheap birch.
Time or more experimentation. You should see the amount of scrap I've burnt through so far.
(ignore the line going from left to right, that's because I reused a sample piece)
