A week ago I decided to rebuild my baby p3 printer. It’s been standing as it had one or two small problems and 2 other printers have been doing all the heavy lifting. So this became a full rebuild it will be a small 20x20x20 printer with a 0.25 nozzle. I had the old bearing shafts in as they where shorter and convenient for mockup as the Z carrier can slide on and off. Those ones where cut before I had a lathe so the end where done by dremel hacksaw and bench grinder. Must have had a rough spot and caught one of the balls sliding through. Stupid mistake. And to add to it I’m not happy the way I did it the Z axis so redo.
I wanted to do mgn12’s for the Z but bloody hell proper hiwin is insanely expensive.
@Michael_Scholtz those corners printed? Do they hold things square/true or did it require manual squaring?
They hold square without the screws in. They have channels that lock into the openbeam so once the screws go in its solid. The frame is good after a print at 0.05mm layer height it came out nice but I can still see bands with the same pitch as the rod. So even after changes still not happy with z. Think it needs a massive rethink.
The bearing will work fine with a few balls missing (less than 5 or so).
I redesigned the z Axiz and will post pics tomorrow. Just printing a few more parts.
