March Release - T-wist 5 Alpha1
🕑 Added 2024-04-01 23:36:31 +0000 UTCToday I have an actual hardware release for you guys! This is the T-wist mk5. It's a cable-driven twist mechanism that moves the weight and fragile electronics of the twist mechanism off the reciever and into a side-mounted box that sits opposite the pitcher mechanism.
This is an Alpha-level release to serve as a proof-of-concept. I'm just releasing the STLs and will be following up with a few refinements and build instructions next month. My advice is that newbies stick to T-wist 4 for the time being, however for those who want to give this a go I recommend that you check out my livestreams from this month (March 2024), and if you have any questions you can ask them in the #maker-chat area of the Discord server. Feel free to @ me there.
The BoM is as follows:
2x 7x3x3mm bearings (ie 7mm outer diameter, 3mm inner diameter, 3mm thick)
A length of 3mm brass rod, cut to 42mm length
A standard size servo (180 or 270 degree)
A circular servo horn
2x ~50cm 4mm PTFE bowden tube (as used on 3D printers)
Steel fishing wire
3x M2x5 bolts and M2 washers - to secure the cable ends and centre point.
12x M3x8 bolts - to close the receiver and secure the servo horn to the drive gear
13x M3x10 bolts - to secure everything else!
I recommend lubricating the moving parts as in the earlier twist mechanisms.
Happy building!

Nope, sorry, not yet.

I just got half way through printing realized there's no SR6 receiver?

That one is actually a display stand that I made for photographing my machines. It would be absolutely no good for anything else.

Awesome! I watched the stream earlier today and can’t wait to try building this. Btw, what is that stand you’re using? I assume you printed it?
