Converting Settings

[Tammy Peruski]

I have the Logilase 9060 (an 80 watt laser) from Logimation Technologies Inc. My settings call for Power, Speed, Corner Power and Scan Gap. I am having a difficult time converting the recommended settings for materials from systems like Epilog or Trotec because they have Raster/Vector Speed, Raster/Vector Power and PPI. Can anyone explain how I convert their settings to what mine uses?

Thanks!

Scan gap is dpi here are some settings you may find useful. I have taken these from the manufacturer of my laser machine.

DPI = SCANGAP
1200 - 0.02116
800 - 0.03175
600 - 0.04233
500 - 0.05080
400 - 0.06350
300 - 0.0846
200 - 0.12700
150 - 0.1693
100 - 0.2540

Regards

Thanks, I have those too. Looking more for the power and speed setting conversion.

Forget trying to compare to Epilog - the speed settings are non-linear, so are pretty meaningless to anyone with a different make of laser.

As a very rough guide for speed of the carriage across the X-beam when rastering -

100% speed - as fast as it will go
75 to 90% speed - nearly as fast as it will go
around 30 to 35% speed - about half it's fastest rate
under 20% speed - very slow
under 10% speed - creeping along

The maximum vectoring speed is much lower than for rastering. I think that this speed setting is also non-linear, but the effect is not so obvious because of the lower max. speed.
On the Epilog, 100% power is full power, whether rastering or vectoring.

The Epilog driver (and, I believe, Trotec and ULS) calculates its own adjustment for going round corners - it is not something that I can set.
I'm not sure if it alters the power or the frequency (dpi), or both.
