Engraving is tilted back, after replacing my Ruida 6445g

[Benvn (Ben van Niersen)]

Hello!

I need your help.

My 80 watt Chinese Laser started to engrave “tilted”.

Please have a look at the picture.
Last week i replaced my Ruida 6445G and from that moment on it is engraving like you see on the picture.
Is it a setting in Ruida or has Lightburn anything to do with it?

Thanks in advance.

Most likely rising edge issue. The following post explains how to fix it:

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…
