Wow that is pretty cool! How much power are we talking?

6 watts average at 10khz pulse rate. Pulses are about 30ns. I dont know what that figures to peak power.

Wow. Nice Square for a hand crank.

Turns out my hand driven square was squarer than the machine did on my first computer controlled test. Turns out I was loosing pulses from the computer to the X axis servo drive. I had the pulse width set too low for the breakout board I was using. OOPS! Now it is moving as it should.

Got the laser cutter out of the front room and back on it's stand in the garage. It was pretty warm out yesterday (85f) and found my chillers could not keep the laser cool in the higher ambient temp. I have and old, old, neslab RTE-5B from Tektronix that looks like it can handle it, made modifications to it today to have it controlled by the laser power supply.

Here's a pic of it on it's stand before I found the chillers dont work very well.
