Not sure if this is allowed - but I am having some weird issues I haven’t come across before.
I am altering the image in Imaengine and saving as an SVG. The preview looks fine - but I’m not sure if this is a software issue, hardware (chuck rotary), or a file issue.
I don’t think it’s the settings in this case - it could be that the cup moved in the rotary, or that you had something else in the file that you didn’t show in the LBRN file. I looked at the project and didn’t see anything that stands out as incorrect.
I thought the same, but when looking at the work, if the cup had moved, there would be distortion. In this case, there is burned areas above and below the solid white stripe and then there is the foggy area where it looks like incomplete burn off of the powder coating:
I never set Min / Max differently when engraving on powder coated steel. There is so much heat sink, so much powder coating to strip, and there isn’t the same concern here for scorching the material like acrylic or wood.
