Raster engraving is skewed but vector cutting is not

[JohnRutledge]

I’m having the same issue that ioniccoatings had back in '19 with his GRBL setup. (vector cuts fine but raster skews). Reducing the resolution helps but is not a fix and remains pronounced on larger projects. I was hoping there is a similar setting (“GRBL $2”) for Ruida to fix my problem. Ive tried different file types and the results are exactly the same which leads me to think it’s a setting in the software. Currently running LB 0.9.22
I’m a noob so any and all help is appreciated.

Thanks in advance,
John

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…

Thank you, I will give it a shot today and let you know.

Thanks, Rick. Cuts perfect now

Set both x & y axis PWM Rising Edge v = Yes
