I am asking again how other people fit there printed parts?
After several months of trying i can not find the solution.
Every part i print that have to attached to an other parts, is not correct.
for example:
all gopro mounts that are on thingiverse wont’t fit the original part. even the parts that i have designed myself don’t fit.
They only fit when i make lager holes, ant thiner parts, but i think that is not how it should work.
I have tried many printer settings te get a better print, but till now i have no succes.
Sometimes people say that you have to scale the parts a bit, but that doesn’t work.
I hope that there is somebody who have a solution, of have good settings for a slicer.
i can’t believe that everybody that print a part from thingiverse, has a part that don’t fit.
Or is it a K8200 problem?
Hi I had a problem like this nothing would fit found out that as I had the z wobble this was stopping them as soon as I sorted that all parts fit together nice
Ronnie, if you load parts from thingiverse (stl) they are always made to fit the machine of the creator.
Ed Printing by now is not an exact science.
How parts are dimensioned heavily depends on the setup.
Axis precision, Hotend type, nozzle size, printing speed and filament used all influence that.
So it’s always a bit trial and error with ready made parts.
Generally it often helps to scale the stl’s of the outer part up a little (say 0.05 to 0.1%) to make
for example pinted nuts fit on a printed bolt.
This problem is caused by the extrucionwide. The nozzle of the extruder for the default K8200 is 0.5mm.
The printed objects will be 0.5 mm bigger because it’s adding the extrucion wide.
Inner cut-out’s or holes are getting 0,5 mm smaller.
To make a print tot exact dimensions you have to disign the outer dimensions 0.5 mm smaller and inner cut-out’s and holes 0,5 mm wider.

The slicing program knows the size of the nozzle, and should compensate, by printing 1/2 of the width of the extruded plastic inside of where the perimeter should be. With a calibrated printer, you should be able to print STL’s the size they are in software. Snap together parts, screw holes the right size, etc.
Calibrating E-steps (covered here on this forum), and messing with the extrusion multiplier, affect the finished size of the object, because they affect how much plastic is squirted out on a given path. The printer can only guess how much it is squirting out, it needs a human to fine tune the amount.
In addition, there is a life saving feature in the current version of Slic3r: XY Compensation.
XY compensation allows you to type in the amount smaller you want the XY dimension to be, and it subtracts it from the object it would have printed, very handy if everything is always a consistent amount (like .5mm) too large, or small.
