Does anyone know why this is happening?
That is usually caused by loose belts. There were some posts on how to adjust them yesterday in the facebook {laser engraving and cutting }group https://www.facebook.com/groups/441613082637047/
Greetings David, i’m not really sure what problem you are trying to show, but I have seen something similar when trying to cut at a speed faster than that my machine could cope with without skipping steps. Kind regards, David.
Looks like loose belts to me. There are tiny access holes that you use a screw driver to tighten the belts. Note: there are two belts on the Y Axis. One on each side.
Its just one belt… The one thats moving “up and down” on the photo
I’d check them all
How do i tighten the belts?
Loose the belt;check if any damage happened on pitch;adjust the turning speed to make it slower when cutting the corner.I guess belt problem is the main reason,maybe.
On mine, I noticed the gantry was crooked, and was causing measurement issues when cutting. I had to loosen the belt, straighten out the gantry, and re tighten the belt. That fixed the issue for me.
with a crooked gantry the start and endpoint is the same… it looks like its missing steps, to loos or to fast. Might even be to tight in combination with to fast (skipping)
David, I note that no one has told you how to tighten (adjust) the belts. For the x-axis, the two adjustment screws (ignore the allen bolts) are on the end of the frame, and can be accessed from the PSU bay. Buggered if I know how to get to the y-axis adjusters, but I haven’t really tried yet.
Thanks I’ll give it a go, since I’ve aligned my mirrors better it seems to have fixed 99.9% of the problem!
