Hi All-long time lurker first time poster!
Thank you all for contributing to a rabbit hole I repeatedly find myself wandering in though it seems I haven’t learnt as much as I thought…
I have a Sculpfun S9 with an extended bed and a reasonably new laptop running the latest version of lightburn.
I tried engraving some anodised/anodized aluminium this morning with an image and got mostly great results. I am really happy with it but one area has lines in it.
I prepped the image using imag-r using norton/aluminium at 318DPI then dropped that into lightburn where I used the same power/speed settings from a tutorial I found.
If anyone could point out what glaringly obvious and stupid thing I have done I would be very grateful.
