Great build series @mvdveer, thanks for sharing your experiences. I've also completed my Tradrack after Christmas and over new year. Nice to have time to tinker 
I'm also using the Mellow CAN board. This is a much easier and economical design. Using a MGN9 rail that came from my V2.4 when I upgraded to the MGN12 on X, I was able to fit up to 19 lanes - this is more than I needed, but it was so easy to add additional lanes because there are virtually no restrictions to expand (apart from a longer Gates belt).
The change I made was to include the mod which allows the Binky sensor to be included and then Happy Hare V2.3+ to be used given all the improvements Moggie has made. 
Did you set yours up using the Annex software or HH?

can you share updated files for mgn12 ??

I don't think he has MGN12 files he is using the MGN9 rail when he upgraded his V2 X axis from an MGN9 to an MGN12.

@CBR900cc unfortunately don't have files for MGN12. As @PFarm said, used the MGN9 from my V2.4 when I put the MGN12 on the x rail. I also have not seen a MGN12 variant or mod for TR so not sure one exists, sorry.

Hey @mvdveer thanks for the details and the full rundown.

Thanks for sharing this. Coverage of the TradRack is pretty scarce, so this is a great resource.

I also seem to enjoy the build more than the use. I built the ERCF 1.1 with both thumper blocks and the default as well as both filament cutters, then 2.0 was dropped and I decided to start all over again. Built 2.0 with both blocks again and added the buffers but I didn't like the buffers attached.

With age and nerve damage dexterity has got up and left and I couldn't stand how crowded the setup was. Printed and built a couple different buffer setups (all 9 lanes!), and  wasn't sold on any of them. Somewhere along the way I found TradRack and now the WinchRack, (htts://github.com/v6cl/WinchRack) which I am really looking forward to building.

So now the fully built ERCF sits sad and cannibalized in the corner. Hopefully this TradRack sticks. I will end up reading this thread a hundred times as soon as I start building.  

Thanks again!

Thank you - it was a fun build. If it wasn't so bulky, the WinchRack would have been the ideal solution, space will be a problem for me personally. But I might give it a go - just because. Thanks for the link!

@mvdveer Here is the other one I had found. Top loading, compact so could be set side by side. https://github.com/muzixiaoyang/3Dprinter-Electric-rewind---filament-rewind---multi-color-printing

Annoyingly long name. Haha

[mvdveer]

Running the tradrack on Happy Hare software. All the calibrations done as described on the happy hare Github. Homing good. Changing tools as required, Feeding filament as required. Test prints to follow when I have some spare time again.

Dunno if you have looked lately but the winchrack has a new revision V0.6 that makes it a lot smaller also uses extrusions and can swap spools easier.

I haven't started my tradrack build but soooon!

Any Progress ?

I'm making one too

I need to get back to my TradRack soon.

I'm waiting for the 623zz bearings, ECAS04 connectors and ERB V2 to arrive

then I'll continue assembling it in a week's time.

Hi,
I'm coming back to this old thread. I'm considering adding this mod to my Tradrack. The filament keeps getting worn down and loses grip, so the Tradrack stops feeding and retracting properly.
I've had multiple prints fail halfway because of it.
Has anyone else experienced this issue, or found a better fix or tip?

Come tutti sapete, ho completato una delle prime build di un ERCF e mi è piaciuto. Dato che lo spazio era limitato a causa di lavori di ristrutturazione, questa unità è stata spostata e ho accarezzato l'idea di costruire un Tridex. Dopo una serie di errori, il progetto è stato abbandonato. Ho iniziato a cercare dei cambiautensili: mi piaceva il cambiautensili Daksh e ho trovato quasi tutti i componenti, ma quello che non sono riuscito a trovare erano i magneti per i fori. Disponibili solo in India, PayPal non accetta pagamenti in rupie e i venditori indiani non esportavano in Australia. Quindi un altro progetto è stato accantonato. 

@PFarm Mi ha rimotivato quando ha iniziato la sua build ERCF con tutte le mod. Ho ordinato e ricevuto un kit Fysetc come punto di partenza. Ho iniziato la ricerca su tutte le mod e sembra che una v2 fosse in arrivo, incorporandole tutte - ah, molto più facile. Beh, ho deciso di aspettare la v2. Nel frattempo ho esaminato altre unità MMU e mi sono imbattuto in Tradrack. Sembrava abbastanza semplice, ma era in beta chiusa. Non più: è stata rilasciata la beta pubblica e ho anticipato il tutto: costruiamo un Tradrack. Non appena ho iniziato la ERCF v2 RC1, è stato rilasciato un progetto della community. (Dovrò approfondire questa questione quando avrò finito Tradrack)

Questo è il mio percorso nell'assemblaggio del Tradrack.

salvea tutti volevo sapere che tipo di servo devo prendere per il tradrack dato che non trovo la sua sigla da nessuna parte grazie a chi mi darà una risposta

According to the BOM for the tradrack, the  SERVO, that is recommended is:

Servo Motor - FEETECH MINI FT1117M, JX Servo PS-1171MG, or Power HD Mini Servo HD-1711MG

Hope this helps.

Great build log—super helpful details, especially around the belting and switch wiring.

I’ve shared a few extra photos and notes from my own setup here if anyone’s interested
