Hi the $30 $ setting needs to be 1000 (power range). If you set it to 2000 then a S parm of 255 with be 1/8th of the laser power. While a power range of 1000 gives this 1/4th of the power range.

When setting the $ setting in the Mini, make sure that the S parm in Light Burn is set to the same value. This is available in Device settings.

My $28 is 2000 at the moment but it is set it LB to 2000.

I have changed the $28 to 1000 and set the S value in LB to match. Re ran the test and the results looks some what the same

Hi, how old is the tube? They last about 800-1000 hours but my first tube was already weak from day one. After replacing it with a reci tube, it finally was able to cut plywood.

Also you can experiment with lower values like 500 and see if it improves. Lower values means a smaller range and is a good indicator that the tube has lost power.

I had similar issues with gray scale in the beginning. I stopped using the post process in lightburn (jarvis,stuki,dither etc) and started editing within coreldraw to suit my laser (proper photo prep IS CRITICAL) then i use the pass-through option and my results have been nothing short of amazing.
