Laser cutter speed difference
Here is the video of my two laser cutters cutting the same tile side by side. It prompted a few people to ask 'how come the 30W tube is much faster than the 100W tube?' I picked the new laser cutter based upon speed. It had a few specification stats that suggested it was fast and the photos showed a fairly lightweight head etc. Now that I have the laser in my possession I can see all the design decisions that make it fast. In the case of these Carcassonne tiles I only need the full power of the laser when I'm cutting the tiles out. The low power engraving lines are done with minimal power, only 8% of the 30W tube. The metal RF tube gives me much more control over the low end power, the head can fly around at 100mm/s, twice the speed of the larger machine. The engraving can be done at 1000mm/s, again nearly twice the speed and empirical evidence suggests that it is actually moving at that speed. The 30W laser can easily handle the 3mm poplar ply wood at a sensible 3...
