Power Scale Help

[kbigmike2121 (Michael K.)]

Hello All:

So I am working with the Power Scale option and am running into an issue I think. So I am trying to create an Engraving Power/Speed Test where I have 10 Rows by 10 Columns and I have my max speed on the spectrum at 350 mm/s and the max power at 95%.

The issue I am running into is that when I run the file, 10% Power at 350 mm/s is coming out really dark.

Am I not using the Power Scale Right? My Layer Settings for example are Speed: 350 mm/s, 100% Power Max, 50% Min, and .07 LPI.

Thanks in advance for the help…

Problem with Lightburn or my understanding

Using a chart from Hurricane Lasers, I was trying to burn a 1" square through 1/2" Oak. I have a 100 watt laser, Chinese, with a Ruida 6442G controller. I used 98 watts at 5 mm/sec per the chart. Barely etched a line in the Oak. I then set the Ruida controller to 98% Power, 5 mm/s speed, Hit the pulse button at the same time I moved the laser with the arrow keys. A VERY satisfactory cut was done. So now I am puzzled. I know the laser should be able to cut 1/2" at one whack… why the discre…

Sorry for so many replies but I also just remembered my issue a few days ago, you have to set a minimum on your color for that speed. Whatever you minimum to get the tube to fire. I have my mine set to 9 and the max to 100%, and my power scale goes from 10% to 95%.

50% min is the reason. Power scale is a percent between min and max, so 10% in your case is 10% of the way from 50% to 95%, or about 54% power.

Okay I’ll give that a try next. That makes sense.
