Z-Axis short on sainsmart PA-CF 25%
So, I recently printed a tall object on my MK4, and my Z dimensions are short, and I would say my X/Y dimensions are big.
.6 nozzle, .25 layer height
I compared a 1"x1" block in overture PLA+ to the same block in this sainsmart PA-CF and here are my measurements. Granted, this is a custom profile I had to create by reading/comparing, etc - I would like to get it closer to true dimensions if possible, but I am not quite sure which things need to be pushed/pulled here. The print came out awesome, just dimensions are a little off.

Nozzle: .6, layer height .25
Basically, for a 25.4mm (1") cube this is what I measured:
X= 25.773 Average + .3733 over length
Y= 25.787 Average + .3867 over length
Z= 25.197Average - 0.2033 under height
for X,Y,Z measurements 3 were taken at high, middle, low/base and averaged. So, it looks like I'm a bit fat in X & Y and squished in Z on this material. Since this is a multi-component assembly and semi-critical... print orientation greatly affects results, and the XYZ squish/short needs to be corrected. The overall finished height is > 150mm, so those Z's being short matter...
So, where do I start in Prusaslicer and or the printer?

RE: Z-Axis short on sainsmart PA-CF 25%
According to math and a cheap-o caliper... .84 might be the right answer. Was .68 at the start.
1.2((1.45+1.42+1.41+1.43)/4)=0.840630472854641

So apparently, there's a different method for prusaslicer... than

What I did...
Filament Settings -> Extrusion Multiplier... That got me a lot closer in prusaslicer, cubes are now acceptable. Learned a lot through this exercise... I think
