PAHT-CF shrinking a lot on my X1C

So i am trying to print parts with PAHT-CF, i did dry it inside the filamentbox on the heatbed for 12hrs, but i still get things that are like .3 too small. When i print the same thing with PETG from another manufacturer i get my stuff within .03 differences.

I tried an Temptower already and changed it to 275°C, Heatbed 100°C. Did flow calibration but it was perfectly set to my eyes. Is PAHT-CF shrinking that much?

Printing on my X1C, with Orca Slicer.

So i printed the orca cube with .5% shrink and got X Y 30.12mm and Z 29.6 after cooling down. Z seems really off.

I seem to have same issue with shrinkage
Parts are smaller than sliced
Did you find a solution for that yet ?

Same problem here! Any updates?

Printed few parts with 0.12mm layer height for Prusa hotend and Z is off a lot!

Part is 9cm (X) by 6cm (Y) by 1.5cm (Z) and it’s 2mm smaller on Z height.

Bambu Lab, when I buy $95/kg filament, I buy it for functional parts, not to print a vase for fun. Parts must be precise!

I can’t find a shrinkage number on Bambu’s site. But ultimately, shrinkage is generally pretty consistent, so I’d suggest printing a calibration cube and doing a little math to find the shrinkage percentage. X&Y are generally the same factor, but Z is generally a separate figure.

In Orca Slicer, the filament profile has a shrinkage adjustment for the XY, but I guess you need to manage the Z on your own because I couldn’t find an adjustment for the Z. Personally, I’d do the base adjustment and see how far off the Z ends up, especially if it is a relatively small print. Also note, the high temps PAHT CF is printed at may play a part in the shrinkage, so if you significantly bump either bed or nozzle temps you could find greater variances.
