Problem with dimensional accuracy on the A1

Bambu Lab A1 Series Troubleshooting
1

Hey guys,

I’m having issues with my regular A1 without AMS.
I experience a significant deviation of Accuracy (0,50mm) and just wanted to ask if that’s a common issue with the A1 or if I just had bad luck with mine.

I pretty much tried everything and it didn’t work out so please tell me what kind of accuracy you measure with your calipers.

Thanks in advance

What filament (ie. PLA, PETG, ASA) are you running. Shrinkage is a real thing and some filament types shrink more than others.

Decent video showing shrinkage and bonus caliper usage content.

PLA+ shrink’s 0,1 - 0,2%

Also it would always shrink the same % on every piece whatever length. I experience different deviations by printed piece size. 0,4-06%

Hi,
I have the same issue, it’s not shrinkage, it is a problem on A1 and A1 mini also.
I get 0.7 mm of error on 150 mm, and 0.25 mm on 15 mm, it’s very high inaccuracy.
I have tried to change e-step but it doesn’t resolve the problem.
I get now :
-19.81 mm instead of 20 mm and 150,25 mm instead of 150 mm in same print.
So no way to compensate it because one is too small and other is toot big !
And also not the same error on X and Y axis !
I have tried all is possible but nothing can compensate these issues.
If Bambulab could help me because my printer isn’t new one and I have bought it from an another user.
