The updates so far have been in a roughly monthly pattern, which is totally unintentional but i like it. It gives everyone time to print and assemble everything just to find out that their build is outdated already. Just kidding, the part updates are minimal this time and i'd dare to say this might be a "final" version, if that even exists. There are however a bunch of new, optional Addons and improvements:
NEMA support
This is something i've been working on the past few weeks. NEMAs are significantly more precise than the cheap 28BY steppers, and together with TMC2209 drivers unload their full potential. My tests have shown a good improvement for tracking and guiding. TMC2209 come wit

It's time to go big!
The OpenAstroMount is finally at v1.0 and has been uploaded to GitHub!
I'll still have to make guides for it, but the BOM and printed parts list are up to date.
Some specs:
Mount weight (without tripod or counterweights): 12kg
84 printed parts
580 screws and nuts
6 meter of aluminum extrusions
Low backlash belted gearboxes 9:1 on RA and DEC for a total reduction of 324:1 (RA) and 234:1 (DEC).
Build in motorisation of ALT and AZ for auto polar alignment.
Performance of 0.5-0.7" avg. RMS (from my shitty balcony).
Cost: around 300-500$ depending on local prices.
For payload i'll give a conservative recommendation
