Printer Specific Installation

hope everyone is doing well

I am gonna share my experiance and how I got my 3DC working after almost 3 months of tinkering and modifying on my printer trying multiple things to get it working reliably, I know probably a lot faced issue after another but hopefully this helps alot

I am gonna list things to help you build it correctly and this is not a starting guide this is for someone who already built it and followed bill's guide or someone else's guide

First thing

I highly recommend mounting your 3DC on the back of your printer otherwise it will keep dragging on the table

second thing I recommend inserting a PTFE where the filament goes in as in the picture above

You need a filament rewinder system (otherwise your filament will tangle and break) a buffer might work haven't tried that

I tried two printable rewinders didn't work well with me

so I built The Filamintalist rewinder which worked really well

I will link their github and a BOM from Aliexpress I found useful and easy to build yours

https://github.com/Enraged-Rabbit-Community/ERCF_v2/tree/master/Recommended_Options/Filamentalist_Rewinder

BOM:

the seller also sells a drybox + hygrometer

Now installing the Clippy

I got a servo from Aliexpress which was rated 7v

the mistake I did I didn't pay attention to the rotation of this servo so it was going anticlockwise and I needed it to go clock wise so I had to open it up reverse it's wires with soldering iron

I will link it just in case you want

https://www.aliexpress.com/item/1943129663.html?spm=a2g0o.order_list.order_list_main.68.3c9d1802TR5Sb3

I also needed a buck converter the 3DC couldn't provide enough voltage to it for some reason

https://www.aliexpress.com/item/1943129663.html?spm=a2g0o.order_list.order_list_main.68.3c9d1802TR5Sb3

(for the servo you need to follow bill's explanation you will need to swap some wires on the connector)

Red and black/brown go to the buck converter

Yellow/Orange goes to the 3DC for signal

I have my servo set to 7.2v wich has enough power to cut easily

the mount I modified bill's mount a little bit I added two rings just where the cutter passes so it doesn't cut the PTFE as mine was slipping alot

this is the TinkerCad file for it

www.tinkercad.com

3D design Generic Digital 3DClippy K1 with ring stoppers created by drmohied with Tinkercad

I recommend adding M3 heat inserts where the servo mounts as with uses the threads will come loose (Printed with PETG) maybe ASA will work better

follow bill's method to mount the clippy it's very simple

Now even after this I had some issues where the filament won't load properly and get stuck just at the start of the extruder, I tried 2mm and 2.5 PTFEs both didn't work so what I did

1. I removed the bowden fitting from the extruder (it's a press fit not glued or screwed)

2. got a 2mm drill bit and drilled untill where gears mount
   

3. inserted a small piece of 2mm PTFE and drilled that too so the filament will have smooth passage to the Extruder gears

4 . then reinserted the Bowden fitting

then you need a PTFE around ~ 20mm from the extruder to where the servo mount sets.

now give it a test, attach a small PTFE try it out if filament's go in and out smoothly

What I do is I set my printer to 220 and use gcode to extrude through ur phone

e.g. G0 E50 F300

and it should grab the filament smoothly and then retract it all the way or just use the servo to cut it

once you're sure it goes in without an effort even when the filament is cut flush now attach the TOP PTFE with appropriate length

Something to mention

the clippy mount will bump into the Lid raiser I still haven't tried to print something, I had to remove it until I figure something out for it

the Front and the Right side raisers

now to come to the Gcode

I would like to thank Bill and Alan as their gcode really helped me build and understand mine

I use OrcaSlicer

swapping filaments should be smooth now and the issue I always had is the loading sometimes it loads and sometimes it doesn't but after trying this method it almost always works

the method I saw one of the Voron users do is they purge a chunk of filament and thy get kicked by the extruder

it extrudes around ~100mm and I set my purge tower(Flush Volumes) to 0.2 Multiplier

here is a video explaining what I mean

Make your profile and copy mine but YOU NEED TO ADJUST LENGTHS

things to note

at the moment I am loading my first filament manually I wait for the start Gcode to end I take the filament once it reaches the extruder and I feed it manually "for now"

if your starting filament isn't T0 then just make sure before you print to change the press time on the starting Gcode (I highlighted it in Red)

I hope this was helpful for K1s out there

Excuse my english I hope I delivered my message clearely

share with me your thoughts and questions

now here are successful prints I did ranging from 30-500 color changes

I know the bottom looks messy I need to make a Poop Collector xD
