MRRF 2022 Preview - ANNEX Trad Rack

Introducing the ANNEX Engineering Trad Rack, a MMU system designed to perform just like our printers. Fast, Amazing and Reliable.

Do you end up having issues with the filament being rolled over multiple times by the spur gear? What about using to rubber rollers where only one is driven?

[@romanshevchuk3146]

ercp for help

[@skybldev]

loving the use of ethernet strands for cabling 👍

[@bassplaya69er]

2 steppers and a servo? Pritty much exactly what I have been meaning to design for the last few years. :) Does it also have cutting mechanism to trim the end of the filliment to avoid messing about with ramming etc?

[@TheHell34]

It does not have a cutters afaik

[@zola5584]

What with this project?:oo

[@user-yk1cw8im4h]

annex stuff is so simple I luv it

[@TheHell34]

It is basically a build from spares

[@textech8946]

difference vs ercf? only the 2020 alu profile and linear rail?

[@ryanbento1565]

no theres no fussing about with those gate washers and magnets and theres also no "encoder" per say but from what i gather its relying on microswitches to tell its positon, when it pulls it in you can hear the switch actuate, push foward x amout then run it back same distance and if it changes state of the switch now it knows where the end of the filament is. simple and very effective. the ercf is a great design but i think a bit over engineered.

[@bubajou]

works on klipper?

[@AnnexEngineering]

It’s designed for klipper

[@zuiaichi-shounai7069]

Looking forward to K3S

[@avejst]

Multi material switcher, Nice :-)

[@dansxmods]

That's so cool

[@erodrigolopez]

That’s beautiful 🤩

[@bothug4981]

This is a really awesome mod. When will this be released?

[@AnnexEngineering]

We don’t do release dates. There’s a sign up for beta in the launch video

[@bothug4981]

@@AnnexEngineering I have submitted on your website， and I really hope to try this mod

[@OERYV]

When will this be released? Super stoked about this design, really digging this design.

[@OERYV]

@@realhusky "This design", was only interested in this as it's much cleaner & simpler.

[@haenselundgretel654]

Wow! That's really amazing!
May I ask how long it takes to design this until it's good to go?

[@AnnexEngineering]

we dont give dates

[@haenselundgretel654]

@@AnnexEngineering no no. That's not what I meant. I mean: how in general does it take from the idea to an almost finished version?

[@user-yk1cw8im4h]

@@haenselundgretel654 few months usually, and another year to have it stabilized.

[@haenselundgretel654]

@@user-yk1cw8im4h That is a bit. But I for myself take minimum that time too to develop new devices.... Unfortunately

[@Funkyskull75]

This is awesome. Have you thought about using larger LGX style drive gears?

[@aharkey1077]

I don't see that happening until someone starts making LGX parts kits similar to how cheap/available BMG kits are. I hope someday that becomes a thing though.

[@davidwang_music]

Why did I build an ERCF 😭 The tip tuning is a nightmare and this could potentially be way better

[@TheHell34]

But looking at the feeding speed, its quicker though.

[@davidwang_music]

@@TheHell34 the feeding speed is all changeable in the config

[@imforpeace9511]

Never had to tune my tips and everything works perfectly. I'm using 2.5 ID and an Orbiter 1.5. Also by the looks of it this does not have an encoder, and whilst the tradrack seems to be easier to make, I don't think that it's a direct upgrade functionality wise. Perhaps the ERCF is overengineered to an extent, but it's an amazing MMU when you get it to work.

[@mikesilva8350]

I want this! Its basically an awesome piece of tech. what a fantastic idea. My 5Plus is ready to test this!
