I just want to say thank you for your video. I just got a 51/100 and SO overwhelmed with all the videos/links that are provided. yours was the most helpful!
I have always been a great fan of Thunderlaser's great machine design and engineering quality along with their many videos as they attempt to make laser cutting easy for the masses. The matrix test card is a great beginners tool to get you working but it is like training wheels on a bicycle, once you understand how to balance, you remove the trainng aids. If you look at the small details of this test matrix you wil hopefully ask yourself several questions: 1) With the cutting test, once the pieces drop out you lose a lot of valuable observational data. However, look closely at the 25mm/s cut speed and note how "smokey" they are in relation to the 5mm/s cut line. Why? Its the same lens, the same focal distance and the same powers. 2)Compare the width of cut (the kerf) between the 25mm/s cut and the 5mm/s cut. Why is the 5mm/s cut twice as wide when its the same lens, the same focal distance and the same power? 3)With the engraving test, I have always been perpexed at what it shows you. It seems to show that as you increase power the colour gets darker. This is a fallacy because if it were true the colour would get darker ON THE SURFACE. Look closer and you will observe that increasing the power is making the engraving deeper and smokier. Again you should ask yourself why this is happening? How useful would this be on thin card? 4)The width of the burnt laser engraving line changes with speed and power. There is no compensation of line spacing in these tests. Slower speeds and greater power means thicker lines and double burning as lines overlap. 5)Focal distance set to the manufacturer's OPTICAL specification rarely gives optimal cutting or engraving performance because your laser beam has an INTENSITY focus that changes with speed, power, material and position on the table. So.these test patterns need to be done at different focal distances to find optimum performance chracteristics. If you never observe these issues, ask questions as to why and look for answers, then you will for ever be stuck with your training wheels. Great as Thunderlaser are they do not really understand the technology they sell beyond skin deep. To extract the best performance from your machine there is so much more to understand. Please watch this video to see how misleading the test matrix can be. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Na5_6okUyKg.html This may whet your appitite to understand more about the technology you have invested in. It is truly amazing and your TL machine can do much more than TL ever imagined.
Hi first of all thank you so much. I have a question my laser name module head 40Watt for diode laser machine. Does the library file work with my laser, Or i have to make a new library ??
