I have a chinese 700x500 machine and I have noticed 'ridges' in the engraved area... attaching pictures of some in plywood and also plastic.
I am using the RDWorks plugin for CorelDraw and seem to have no issues with anything there. Have taken all the default settings.
Thoughts on cause?
I know the pictures kinda suck and it's hard to see but there are ridges in the engraved area running from right to left.
Maybe a little easier to see in the black areas of the engraving
Thanks in advance,
