Marks made in the material tester do not match those made in the project window. Ill find values I like from the test, input them onto the project cut settings identically and the burn is nowhere near the same. I’ve checked units mm/min mm/sec and inches vs mm. made from default with no libraries open. Both settings are identical in the material settings for the test and for the project. Not sure what the issue is. Running version 1.7.08
Can you give more specifics? What range of settings are you testing? With what kind of laser? What size of squares are you using, and on what material?
I ask because, depending on the device, and what your goal is, things can and will vary somewhat.
For example, if you’re trying to find good settings for cutting with a CO2 laser, and you using small squares, the speed of a square might say “200mm/sec”, but since the square is so small, the laser head isn’t going to have room to actually get up to that speed, which might mislead you.
For galvos, if you’re chasing color engraving, the temperature of the material plays a role, so running a long test might heat the material a bunch and then start producing good color, whereas using one of those settings on cold material without warming it first might produce a different result.
Its a 100w JPT MOPA, settings that im using:
Speed 325mm/s
Power 30%
Frequency 100kHz
Q width 134ns
Interval .100 mm
Material stainless steel, looking for annealed mark the tester produced nice black 10mm square then in project it was more whitish - not black.
In the tester i even limited the square count to only 2 squares at the target settings. Tester produced the black, outside the tester it was not.
Was it the exact same piece of steel in both cases?
What works for annealing a 1mm square area of the material for a specific color, usually wont render the same results if enlarged or the material is of a different size.
I believe this has to do with the metals thermal conduction..
These are the settings I used for this dollar store stainless steel kitchen knife. An F254mm lens – MOPA M7 JPT 60W.

Yes same piece
So I’m not quite sure yet why, but i went and tried this again and they match. Maybe just resetting the machine / computer fixed this issue or it’s something I’m too new to specifically diagnose, but either way its working as intended. Thanks for the replies
