Fiberon PA-612 and PETCF Printer Profiles Prusa

remsShots

Can anyone point me to a PA-612 or PETCF profile for the Prusa Mk4S? I am having trouble locating a profile and I have been having a damn time figuring out shrinkage compensation and cooling settings on my own.

Specifically, the last lower I made in PA-612 ended up about a mill too long after printing out a few calibration pieces and calculating the percentage difference in size after annealing and inputting that difference into my slicer. I haven't had much more luck with PETCF.

Any information or procedures for narrowing down settings would be greatly appreciated!

remsShots Shrinkage is highly depended on the axis. "Absolute" shrinkage tends to be small, but line to line and layer to layer can be much higher. You need to check each of these separately. Because lowers are mostly walls, the absolute shrinkage is the number to use on the X and Y. But the Z shrink will be greater.

Measure the absolute shrinkage with a bar that has aligned infill running the length (100%). Measure Z shrink with a vertical bar. Make the bars at least three inches long / tall to get solid measurements.
