After successfully finishing an engrave, score, and cut on aspen, I uploaded another artwork, set the various parameters to same values as previously worked, and printed when the white blinking light came on. The score and cut operations worked fine but the engrave failed: the laser, parameters 1000, Full, failed to turn on. The gantry moved as it should, but there was no engraving.
I’ve re-opened the file, re-entered the parameters, cycled AC power without helping.
Any thoughts? ARRRGH.
