March Update
🕑 Added 2022-03-01 23:14:26 +0000 UTCHi Guys, here's my update for March.
This month I'm excited to announce that I have quite a significant upgrade to the twist mechanism to release.
With all the work on SR6 Beta it's been a while since I gave the OSR2 some proper attention. The twist axis seems to be the most popular axis on the OSR2, after the main up-down axis of course. In my mind it was overdue for an upgrade.
I've released three versions of the twist so far, but up until now none of them have been completely satisfactory. The current version is okay, but it does require a Parallax 360 feedback servo, and those aren't easy for everybody to find. The feedback system is also a pain in the ass to troubleshoot.
This release is special because I have designed a new twist mechanism that will work with a generic standard sized servo. The mechanism employs an additional gear so that the main ring gear moves with a 1:1 ratio with the movement of the servo. Just pick yourself a 180-degree or 270-degree servo, plug it in like every other axis on the OSR2, and you're good to go. It's simple, smooth, fast, and works really well. It's also incredibly easy to put together.
I will be releasing the part STLs and a set of build instructions for the T-wist mk4 in the next few days on the Maker tier. I've spent a crazy amount of time on this over the last month and I'm excited to share it. Currently this is an OSR2-only design, but the design is transferrable to SR6 and that will be coming your way at the beginning of next month.
Other news: the Discord livestream dates this month for my Supporter tier will be: Monday 7th and Monday 21st March. These will start at 11pm GMT (5pm EST). In these I will be building an OSR2 and the various add-on modules and taking pictures, so that I can update the OSR2 build document. I will be building both the Romeo and ESP32 versions. This would be a great opportunity for any newbies with questions on the OSR2 to drop by.
Sometime this month I will also publish my T-Code guide, which I recorded in the livestream last month.
A big thanks to everyone who supports my work. It's because of you that I can keep improving these machines in this way!

(Update 5-3-22: Latest firmware attached, for Romeo and ESP32. This firmware works with the new T-wist, though the old version with the Parallax servo is still a selectable option.)

Thank you for this twist upgrade. I am hardly been able to wait! The improved speed should add some interesting jiggle potential!

I wouldn’t worry about the feedback issues. It seems to be a relatively rare occurrence, it’s just a pain when it happens. I’d say build what you’ve got. It’s a month or so before I release the SR6 twist. I’m going to continue to support the parallax servo in software for the foreseeable future.

I just had a Parallax delivered today (still in box unopened). Would you say it’s worth it to exchange it for a regular servo before I move forward building an SR6 this month? This is my first time hearing of feedback troubleshooting issues.
