Fuzzy Edges on Engrave with Lightburn - works fine with other sofware

[Dominic (here to help.)]

Firsty @polarbrainfreeze thank you for providing so much information and screenshots and all the rest this makes me very happy to see!

I wonder if the issue is related to PWM Rising Edge Valid…? Though usually this issue presents as a slanted engraving. See this post:

How do I fix skewed or slanted engraving?

This is an example of a fill followed by a cut around the letter A: [image] The fill is slanted, but the cut appears to be correct. If you have engraving that is slanting to one side, but cuts appear correctly, you likely have your motor pulse step polarity set incorrectly. On Ruida controllers, there’s a setting called ‘PWM Rising Edge Valid’ that you can change for each axis that tells the controller whether the rising edge or falling edge of a step pulse is what the motor driver is lookin…

Your image reminds me of what happens when there is a loose mirror or an alignment problem (the shadowing) but by trying on both LightBurn and RDWorks (Thunder Software) you’ve eliminated that as an issue.
