Double image burning

But the fill (same image as the lines) seems to skew to the right. I cant figure out why on line form, its perfectly straight, but ONLY while doing fill the issue arises.

Please test leading edge vs trailing edge and let us know.

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…

Well hell, I didn’t know that was a link, I thought it was an ad! Reading it now, and it looks like it matches my symptoms. Gonna try it out tonight!

Thank you so much! Imma let you know.

I believe this is what @micrololin had advised…

Ok, I tried the stock PWM settings to X and Y off, X and Y on, X on Y off, X off Y on. Item still skews, just to the left or right of the line cut box. The line box is set to 50 mm height and width, which is dead on per a caliper, and verified via diagonal measurements.

Im getting frustrated.

I believe the setting should be the same for both x and y. Both of mine are off.

I would try to do the same square test on all 4 corners of the bed and the center to see if there is any variation.

I would also cut this file out and check beam alignment at the nozzle in all 4 corners and center.

This file came from this forum but I couldn’t find it to link to.

Update. I ran the laser with all 4 possible pwm setting combo’s, all it did was change the skew from right to left. I have cut the boxes in all 4 corners of the machine bed, with the same results in each location. Im stumped.

FIXED!!

Ok, after everything i tried, belt tension, pulley tension, hardware and software it turns out one of the side dip switches of the x controller was initially set at the factory incorrectly, and sent to me in the wrong configuration. Laguna tech support over a week or so of texting and emails helped me to find it. All is good in the world today.

FYI x and y controller should have matching dip switch settings on both front and side.

@Mike96734

switches of the x controller

What X controller? Are you referring to the motor driver?
