Printer prints good but after a while the printhead moves a little

I have already printed several things with my vertex delta that printed beautifully but each print when it was almost printed the printer moved a little and then printed on. (It is always only 1 layer, there is no layer shifting). Below you have an example. Please help.

Hi @Maks

I think the tension of the belts are wrong, make them adjustable, see my topics.

Kind regards,
Tom

Hi @TomE

Thank you for responding. The belts were a bit loose but when i tried to adjust it, it wouldn’t go any higher…

Hi @Maks
Did you make them adjustable?
That is important, to get them alright and all the same.
If you pull them, they must make a low sound and all 3 the same.
Also, possible that if you use the standard magnets, that 1 came lose while printing.
I use super magnets, after 2 months mine magnets were copper and came loose easy.
See my topics.
Here how you go with the prints.

Kind regards,
Tom

Yes I did make them adjustable but they won’t go any further. I think that I will buy the magnets and then I will see if there is still a problem. Is a traction of 1.2 kg good?

Hi @Maks ,

I think that’s enough. I dont understand “they won’t go any further” because mine have a lot of space to go further!


Hope the magnet will do the trick, here from you.
