Tuning on Dorian

Fantastic news. I can hardly wait to try it out nice.

What does it mean and why does it matter? A: For a lot of jobs it will not matter. But for some special use cases it can make a big difference. Most of the time cutting plywood is just cutting plywood so you don’t need to worry about it. But when you start pushing the envelope on a machine’s capability it becomes clear that all lasers are not created equal.

Tarkin and Dorian are good examples. Dorian uses a High Voltage Direct Current -excited laser tube, Tarkin instead uses Radio Frequency and has an RF - excited laser tube (High Voltage Alternating Current). This is one of the reasons we see differences between the two lasers in performance.

One instance when this happens is the need for more precise control on power output. A good example appears during a cut when the laser head is moving towards a corner. Head movement has to slow down and briefly stop before it can accelerate in a new direction. The controller has to throttle the laser output power or else the material will be blown out near the corner. Tarkin’s tube can throttle down but Dorian’s tube has traditionally stopped lazing around 20%, before the laser head has reached the corner of the cut. So we say ‘Dorian has no low end.’ But this fact doesn’t make a difference most of the time.

I’m not a raster / fill guy so I have no experience there. But I like to cut all the things and use the lasers for mostly quick prototyping and engineering during a build. I have some material that is heavier than paper but lighter than most card stock. While trying to cut fine details in very light material tube type limitations become more apparent.

Thanks Danny
