Another ERCF Project - 6 Filament

[PFarm]

Started printing main body parts for the ERCF Matter3d ABS CF Black. The accent parts are  Matter3D ABS Yellow. Like most on here, we can't leave anything stock LOL! Decided to do the following mods, Bindy, Sturdy Bunny, Triple Decky, Happy Hare and Filamentrix. Parts are ordered less the motors since I already had the 14/17 steppers. Also had the 2020 extrusion for the Sturdy Bunny. The kit also came with a Canbus board. So some parts will be absolute because of the mods.

Printing Triple Decky parts

Might have to revive my ERCF - too many mods to resist. The Dash Toolchanger seems a no-go as I cannot source the ring magnets. Apparently a version two is coming out, but I see ERCF has improved heaps and I have a fully functional unit.  Note to self - Finish what you're doing first before jumping on the bandwagon. But jump I will!

@PFarm Nice. Looking forward to seeing your progress.

I might have to do an ECRF or something filament switchy in the future.

[PFarm]

@mvdveer I know that would get your attention after all you are the mod king!

I'm having the same awful thoughts.

Printed the Sturdy Bunny, Filamentrix and Triple Decky parts. Love the Matter3D ABS CF so I reprinted the SB Mellow Halo body. Need to trim the 2020 to length.

The Triple Decky C7 option is the latest updated component it uses a servo arm with three possible positions in the software, the filament block and the top hat have built-in supports in the stl, so you'll need to get them removed for assembly. Note that the support for the top hat has already been removed in the photo below. The filament block base screws directly to the 2020 extrusion.

 

Run an exacto knife along the two edges for the support then pry up with a flathead screwdriver. Make sure to clean up and support left behind.

Still waiting for parts to arrive, in the meantime printing the last piece for the Pika Buffer.

Like to thank @StalkS for his write-up on the Mellow ERCF Canbus board. https://www.teamfdm.com/tutorials/article/98-mellow-ercf-fly-board-v11-usb-setup/ Received the ERFC kits yesterday so some progress on the assembly. Was a little tricky going back between the ERCF manual and the mod assembly manuals but got it done.

I had shortened the D shaft from 12.7 to 10mm thinking I had to install an 85zz bearing on the hinge plate but as you can see in the photo it was needed since all the filament block has a bearing.

The Triple Decky mod allows for the use of four magnets but not necessary. The filament feed is adjusted and the grub screws Loctite and tightened. Filament blocks are installed directly to the extrusion elimination of the 5mm threaded rod.

The gear box top cover has a notch for the routing of the stepper motor wiring.

They comes out of the bottom cover along with the end stop wires

Had to shave the TC2209 heat sinks since the selector was rubbing on them.

Next step is the wiring, configuration and calibrating/testing.

Wiring completed with the exception of the Servo connection and the Encoder. Waiting for Binky to arrive to complete.

Easy Bird Can wired

Need to terminate Servo and Binky

Seeing this it makes me itch to upgrade my ERCF to v2.. already have the new sensor. (at least, if I can find it in the mess)  

For the buffer, I finally found my solution to all issues, and went for the self retracting spindle holders, finally something that works... without adding drag.

Its such a fun build, but man... buffers were a headache... tried all of them I think...

 

[PFarm]

Decide to try this upgrade to the printer, all of the STL for the printed parts are available on their website. The metal parts are 229 euro, I can get a lot of metal cut and bent for that price! Going to try and use the Pika buffer and ERCF with some modifications. The spool holder does have a self-rewind setup. Like the idea of using the enclosure to keep the filament dry, a longer warm-up time is expected. I'll most likely reverse the setup so ERCF is at the back of the printer and the access door for the spool at the front of the printer

Started printing the hat for the Voron 2.4 350.

 

 

Auto rewind setup.

One more row to print for this 11hrs print love the Matter3D ABS CF.

Drybox, great idea, but I myself reverted from bolting stuff to my printer, I dont like it that it becomes so hard to move/tilt it since I often experiment with it and need to get to the electronics.

So I try to bold everything to the wall

I get what your saying it will be tricker to access electronics but it's only 8 screws and the top comes off. But like you mentioned if you need access to electronics on a regular back the wall mount makes sense. My setup is in the middle of my workshop to wall access is not readily available without re-arranging the shop.

I did buy a kit from Fysetc on Aliexpress last august. Did not get to building the kit.

I did watch the 'intro' video from Nero on Youtube. A waste-block as big as the print itself... It did not really make me enthousiastic...

However I did start a few weeks ago, with the manual and printed the first few parts. Then I ran into this post and was a bit surprised to see so many new 'mods' to the quite 'new' v1.1 of the ERCF.

I decided to try to follow... I thought the best place to start would be the 'sturdybunny'. I did download the git repository. Then another one and got quite lost in how to decide what to print first.

Luckily a google search showed https://sakitume.github.io/Custom-ERCF-Build-Sakitume-Edition/index.html this. Sakitume references your post even in the beginning of his 'log'. He writes very clearly what parts to print and how to combine all the different 'mods'. I liked it, so I started printing according to his documentation, which makes a lot of sense. He refers to his discord channel, which I also visited. There I read that the official ERCF version 2 will be published before the end of this year... I guess that is 2023, right? Only 4 weeks left.

I thought I'd share... 

I already have printed about half of the parts, so I think I will finish printing it before v2 will appear.

Thanks for sharing the info!

Decided to go a different route regarding spool holder mounting and using the Carrot Quiver Buffer. Since the buffer mounts to the back of the V2.4, I'm going to do the hood-style mod for the electronic bay access less the gas struts since I'd like to keep the bottom panel whole (no cut-out for the struts). I'll find another means of supporting the bed when accessing the electronics bay.

 

Spool holder mounted above the V2.4 using these:

Now that's an impressive feed setup!

[Penatr8tor]

@PFarm Just curious, what's the feed length for the filament?

Agree with @claudermilk, Really impressive feed setup. 

[PFarm]

Thanks @claudermilk @Penatr8tor the photos are from Printable for the holder just an example of a setup, my setup will have the spools closer together but the same idea on feeding the filament to the buffers. I'll post my photos and have the length for you when I've got it installed. I've read that you should keep lengths within 1 meter.

At this point, did you build the Filametrix ?

Wondering if tool cardridges can be swapped, or even replaced with standard ones... Looking at the drawings, it seems it is not the case.

[PFarm]

@YaaJ Fliametrix is printed just need to install it.

[PFarm]

Started the hood style mod for the V2.4

 

Used the Trident inverted electronic bay bin supports

 

Put M5s through the bottom panel for better support

 

Time to put it back together

Received the hinges for the bed frame 2020. Found these on Amazon the handle shown in the first photo is spring load so you can ratchet it in place, works well with the limited space available.

 

Got the bed wiring re-connected into the wagos. With the kinematic bed mounts, there was no need for the stl cross piece.

Front handle installed, I've used the Trident bedfan mounts to secure the two bedfans to the bed 2020 frame.

The bottom part of the handle is secured to the 2020 frame.
