Hello,
my Fisher started to do prints with problems recently. I have no clue what it can cause the issue. I moved the printer a lot because I showed it to friends.

I am attaching some reference pics, hope someone can point me in the right direction.

At a guess Id say you have something loose.

check all 12 balls are tight on the screws,
check the linear bearings are tight in the carriages,
check the arms are not cracked
check the belt drive gears are tight on the motor shafts.

Thanks for the input bgkdavis,
I checked all what you suggested and now is printing slightly better compared to the initial prints.

Some of the plexy rods still have parts that are ruined like this ones. Should I get new plexy rods?

I love this printer but I new to deltas.

Make yourself a set of carbon fibre replacement arms - you won't be disappointed. There's lots of details in this forum but here's a link to get you started.

I will look for carbon fiber replacement, in the meantime can you confirm if I need to replace the rods when they are so ruined?

Those marks are telling your something, they are rubbing, you need to identify what they are rubbing on and fix it.

The arms are probably OK for now, but you should definitely look at making a set of carbon arms, the acrylic arms break.

I will look into making carbon arms, is anyone selling them already?

In the meantime I cutted new acrilyc arms and now it prints fine. On the left with old arms on the right the new ones.
