As the title says, this is the best tolerance test I’ve been able to produce since I first started printing a few years ago. There’s stringing, but that would be solved if I dried it, yes I dry pla too. This print is the Sci3d Clearance Test as downloaded in January 2023, from 0.5mm to 0.15mm clearances.
Every spinner is loose and easily moves, I actually had a bit of trouble with the center spindle due to a bit of over extrusion on the top layers.
My machine is a modified ender 3 pro with Klipper. Currently have a 0.4mm hardened steel nozzle mounted with 0.2mm layer heights.
Sliced with the latest release prusaslicer, custom printer, filament, and print profiles.
The filament is one of my favorite PLAs, Voxel PLA, this one is red, but they all print the same for me.
Sorry for the boring post, but this was a huge achievement for me and basically everyone I know wouldn’t understand the magnitude of this kind of repeatable precision on such a low cost machine.
The only place I know to get it is direct from their site.
I’m not sure that you do, as far as I know, being able to move them is the only test. I’m printing a torture toaster now to see if I’m getting similar results with that. I know there are more precise ways to measure dimensional accuracy, but I’ve always been able to print a decent benchy and calibration cube. Actual applications have been less successful.
