I have a problem with my Phecda (20W + air system)
I’m using Ligthburn with this config file
Look at my test :
As you can see, i have some problem.
How is it possible ?
I try to block my wood (it does not move). I don’t think there’s any problem with the slide or friction.
Have you some idea to help me ?
Thanks !
What is weird with the text? Looks fine to me. You might have set it to fill instead of line, but it looks good.
The circles are a sign of incorrect mechanics setup, check it carefully again (here are some hints: Guide to mechanical adjustments and maintenance) It’s mainly your y-axis that is not working correctly.
That’s mechanical problem.
Start with:
That looks like at some point you have a problem. Mostly on X axis at 100% power and Y axis at all “engrave” test.
For the text, il you lookt close at 300, 600 or 3000 there is a difference with other zeros 
I will take a look at your wiki thanks !
I tried to fix my machine.
It wasn’t straight at all.
But after fixing it, I have a problem
I tried to cut 2 times.
Once by putting my sheet of wood in landscape, and once in portrait and reversing its position on Ligthburn.
But the offset is EXACTLY the same.
It looks too suspicious to me for it to be a problem of belt tension or something, because each element isn’t cut in the same place in terms of X/Y axis.
Is it possible i have a problem with my driver of something else?
I don’t believe in a driver problem, definitely something else.
How does it shows on preview window?
Are you willing to share the file for for analysis by those who can help?
Hey @Kuth
Here the preview mode :
Here the files :
player.lbrn2 (123,9 Ko)
equipment.lbrn2 (153,6 Ko)
So the drawing seems perfect to me, with no reason for what is happening.
I found some open shapes (outlined in red) that, although I don’t think they justify the problem, I would close them.
I believe it will be necessary to check the board settings related to motor control.
In the “Console” window you type $$ (press enter) and place a print screen of the result here so that it can be evaluated. I don’t have much experience in this, but there are plenty of people who do.

ok```Those pictures show a mechanical issue. The y-axis is losing steps on its way. The only way to resolve it is to get the mechanics running correctly.
Ok i got the solution.
This was not the belt but this :
The machine has loose screws, and the screws between the optical shaft and the Y-axis stepper motor are not tightened. Please firmly grasp the optical shaft with your hand (try to grasp the optical shaft itself or the coupling), and then push the X-axis back and forth with the other hand to see if you can push it in a small range.

This was also mentioned in the link I posted in the beginning 
Mechanical problem as all we mentioned from start.
Problem solved is the better “music” we like to hear.
