it would be very helpful if people would actually post the link that has the information in question — we all spend a dump load of time fixing & searching as it is — just makes life easier – otherwise we all could give a basic answer of sounds like your "_______ " check the internet for it ---- which can lead to a ton more wasted time ---- just a thought — wasn’t ment to be rude
Life would also be easier if people who have problems first search the forum. It really makes no sense if every question is asked a hundred times.
To find posts relating this question and solve “layer shifting” problem is not that difficult in this forum ;-). In taking one or more pictures and post them you need almost more time than in searching the forum.
If you don´t want to waste your time why do you waste the time of other people because of reading always the same posts and answering always the same questions?
I checked the entire forum(or at least all the posts that were relevant and that i could read), and i tried to fix the xy carriage, but that still didn’t fix the problems. I tried the fix the xy carriage 3-4 times and either i can’t do it right or there is another issue. No matter where I put the model in the software something always goes wrong. and no matter what i do my printer still doesn’t print straight lines.
So i will keep trying all that i can to fix it. I will try to fix the xy alignment again. So at this point do you have any suggestions to help with this process?

you have to check the belts, if they rub against each other ,and check if the careriage run easily in both x and y direction,and if it dont,then try to go back to the manual about how to make the asambly correct …I had problems with layershift, and the reason was, I think, the rods in the carriage do not sit perfect 90 degrees to each other.So when I try to allign the rods with the sides, then I have a problem ,and after taking the alignment with the sides less serious ,my problem is gone.
also the distance between the rods, where it will give more force in the end, must be checked and fixed if there are more resistance… this, I think is also mentioned in the assambly manual
I read that three belts can’t be too tight, and I was wondering if that included the two smallest belts connected to the stepper motor. I ask because my belts in that spot, seem extremely tight. I can’t seem to loosen them either.
[quote=“Redicrowsifix”]I was wondering if that included the two smallest belts connected to the stepper motor.

[quote=“Redicrowsifix”]I can’t seem to loosen them either.[/quote]You just have to loosen the bolds holding the motor in place. If you do this take the opportunity to tilt the motor a bit so the 2 belts don’t rub against each other.
I know this is a little while later than the last post but i have another question. Earlier i took apart the all the belts and all the rods i greased them and i spent a long time trying to align them and what i ended up with was (without the belts on) the printhead moved freely from one side to the other when i tilted the printer 45 degrees. so it seemed perfect.
However, when i put the belts back on the resistance increased greatly and it would no longer slide easily. I expected alittle more resistance because of the belts but not this much. and so i decided to go ahead and try a print the shifting continued… i suspect the belts are too tight. I will take it apart again and try the process again but is there a way i can check if the belts are too loose or too tight? How much is too much?
Also the belts sometimes are tighter on the top of the belt than the bottom… Is that normal? What can i do to fix it?
And while I am asking I am using a lubricant for the bars that i suspect may not do the job properly (or at least not as well as it could be). I am using “Blaster Powerful the dry lube” it says it is made with ptfe… I don’t know if this one is good enough. what lubricant do you suggest? And will this one work? Also How often should I lubricate the rods?

[/quote]The tension for the long belts you can see on the picture below :
The short belts must be tight and not slack like the long ones, or they’ll slip.
[quote=“Redicrowsifix”]what lubricant do you suggest? [/quote]Plain machine oil or silicone oil will do the job (I’m applying it with a cloth to avoid spraying it everywhere and it cleans the rods at the same time). I don’t know yours. I’m lubricating every 2 or 3 days of use or when the rods are dirty (dust sticks to the oil).
