X1-Carbon did NOT Print true to size

Given the way they have been marketing this printer, I don’t think that assumption was foolish.

Yeah. Also can’t discount the “new toy” factor. We may be older but we all get excited for a new toy, they’re just more expensive toys LOL

The difference between men and boys are the price of their toys. :smiley:

Has anyone found any settings that fix the issue using the Bambu PAHT-CF filament?
I printed a ring and the outer radius and height is perfect but the inner radius is .8mm smaller than in the 3D model. I need this ring to fit flush with no more then +/- .2mm tolerance. For extra detail the ring is supposed to be 1.5mm thick, but is 1.9mm thick instead.

I am also having dimensional issues with the PATH-CF material. My larger parts are coming out about 1mm shy of where they should be and also there are some weird step artifacts in the print from support material swapping delays. I require at least +/- 0.2mm generally for my parts. I’m going to play around with the scaling/shrinkage percent settings to see if I can resolve.

I’m also trying to dial in PC-CF material which I have found to be the most dimensionally stable/accurate while having great finish and strength. It has its own set of adhesion/oozing issues but those seem solvable.

Dunno if it’s been mentioned but Orca Slicer (the fork version) has a shrinkage setting just for this specific issue.

Only in Case, your former Flow Ratio (FR) was 1,00. If not, what I think is: you need to multiply the old FR with the calculated FR to get the correct FR.

But in both cases, the actual wall thickness is not 2 times 0.4 becouse of the overlap.
