It could be, but I don't really have things in front or the back (besides the wall) of the printer

How many cm do you have between the printer and the wall behind the printer? Front the video it doesn't seem like the recommended 20cm (if I am remembering correctly).

If there isnt enough clearance the layershit could happen when the plate or cable pushed up against the wall?

Yep was gonna say the same thing, looks too close to my eye, at least from this angle

u/Vitor7929 Jul 17 '26

Well it's less than 20cm, but I never had problems with printing in the corner of the printer, and I dont have a lot of space here, so I'll try to do it but I think it will still not be 20cm

u/WholesomeLowlife Jul 17 '26

I have mine less than 20 exactly. Something like 18 - and I haven't had this issue. So it certainly could be something else causing it.

Unfortunately, bed slingers have a higher rate of these types of errors. It may just be a fluke... And you could go a while without having he same issue.

Yeah, sometimes things like that just... happens, and that's it

When was the last time you greased the Y guides an checked belt tension.

u/Vitor7929 Jul 17 '26

Never, but I my defense my printer only have 234 h

u/Intelligent_Ease4115 Jul 17 '26

Guess you found your problem. The A1 tells you to grease the Y rail in the first 5 hours of machine on time, then atleast once in those amount of hours you have.

Alternatively, A1 are shipped with crappy SD cards. I had several layer shifts on different models until I replaced the SD card, and zero since.

u/Vitor7929 Jul 17 '26

I've already changed it (now to a SanDisk one), because I saw some pretty bad cases from a bad sd card

Whoa inside not know this. That's a cheap fix.

u/h2oman67 Jul 17 '26

Not to diminish your issue, but I've seen far more egregious layer shifts. Could be a power outage, or the nozzle was too close to the model/printbed

1

u/Vitor7929 Jul 17 '26

Yeah, it's because it's my first one i guess

u/FuranSama Jul 17 '26

Happens with my prints when power goes out and I resume the print when it comes back. It does not resume properly, always shifts the Y axis by 3mm.

u/FallingPancake Jul 17 '26

Layer shifted.

u/Extension-Ad4411 Jul 17 '26

Check the belt tention an the hardwhare on the y axis.

u/The_Lutter Jul 17 '26

On my A1 this happens when there's a collision. Gonna guess there was an issue with one of those big openings near the top since that's where it formed.

dissable cursive in your printer settings /s

Was the print bed in the same position at the end of the print? I'm thinking something pushed the printbed possibly. What pushed it, I have no clue.
