Every print - all calibration done, flow, etc. Printer prints without problems, test cube 1x1x1cm - has ~10.00mm in any axis (my caliper is not great)
Im trying to get this Spool (re)winder work - lots of hours of printing… and anything I try - going bad.
When I push clasic stock 608ZZ bearing into base - dont fit, too tight, when I use some force - base breaks in layer axis.
Printed axes dont fit into printed gearwheels (must use hamer, and something often is broken))
axes dont fit into bearings - too tight. (axes was routed and polished by sandpaper, to get better round shape)
etc.
In “clasic 3d printer with marlin firmware etc” i think I will be doing flow calibration, E-steps etc, or something - if axis dimension is good, but holes are too tight, but here? What else I can do?
(my belts is tight, and rods are clear and was cleaned so support 1st ansfer “clear rods” is not good here)
Rather than struggle with calibration flow since it seems like your printer is calibrated well enough to make a cube the correct size, you may have to scale the parts to get the bearings to fit. Find the smallest part that a bearing presses into and scale it a small percentage larger. Maybe 2-5%, then try to fit the bearing. For the parts that fit the bearing ID, scale them a tad smaller.
Ok, I do this when I can - but what when printing gear wheels - whitch is too tight inside for axis, and too big outside (and work with big load and wear quickly).
I would say that “the project is bad” - but I see that hundreds of people are printing it, and just like the author - it works very smoothly, it spins on its own. But in the comments to this project, some people are reporting the same problem - and they were printing on bambu - so maybe something is up?

(because others printed e.g. on Prusa, they probably used “naked” Prusaslicer)
I can’t figure out where the error occurs - because if, for example, the factory bearings do not match the printout - then either the printout is in the wrong scale (why? bad design? bad slicer? Normally I would say “wrong x/y steps in the printer”), or the printout has a good overall dimension, but there is a bit too much filament, it leaks beyond the outline and the object “swells” by part of the line thickness. Well, but if there was overextrusion - it would be visible, for example, on the first layer, which is perfect. And the calibration cube wouldn’t be so perfect
People without a Bambu printer (for instance an Ender3) adjust their STL by designing until all parts fit. When you do print the parts with a Bambu, it won’t fit.
