Printopus

Printopus The printer with everything you need!

Made by: Atharv Sharma aka scattercat_123 | Slack id = scattercat_123

Repository link: Click mE!

Total hours so far: 75+ BTW I have an Ender 3 V3 KE really fast

Before we Start!! :

What is special in this printer:

Auto bed leveling
Working on adding a filament dryer mount in my printer with a bowden setup! First of its kind.
Auto Print remover + cleaner with servo!!!(i will add the wedge later so that i will know the bed height before adding it) -------------------------------->
Input shaping mounts added with adxl343 accelerometer
No more Z-Banding(dont ask me about my old printer z banding) I have added Aluminum Flexible Jaw Spider Shaft which reduces the chance of z banding.
My printer looks sci-fi with a Sci-fi Themed PRINTER HOLDer!! woohoo

If you are wondering how i will add my filament dry box i have already cut a hole in the dry box to fit my bowden setup

yeah since i am using bowden i will cut a hole in my filament dryer and mount it sideways next to the bondtech extruder! I have already cut the hole lol

Day 1 (13th Feb 2025) :

Total time 1.5 hour!!! Started from 6pm

1st 30 mins Off to a great start!

I researched many printers I could make including this one for the basic idea -

The whole video playlist!

The other 1 Hour

Researched some more parts and… I made this mindmap for my printer

And this is the end of DAY 1!! I am so sleep deprived :(

Day 2 (14th Feb 2025) :

Total Time 2 Hours!!! Started from 3:15 pm

Designing and finding the frame! I am using some extrusions! I researched for a long time.. Not kidding :( Time for extrusion frames cheap and good quality with fast shipping and I found these- https://www.3dprintronics.com/products/aluminium-extrusions Researched the SKR Mainboard - https://robu.in/product/bigtreetech-skr-v1-4-control-board/?gad_source=4&gclid=CjwKCAiAk8G9BhA0EiwAOQxmfhkp0i08jJYeySLA4vNOAmef0a8bFC9ivwNMua4mY5DsqRokWoi2nBoCKCMQAvD_BwE I had to figure out how does UART Stepper motors are compatible with it also. The motors(stepper) - https://robocraze.com/products/17hs4401-nema17-stepper-motor-40mm?variant=42490709246176&country=IN&currency=INR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&campaignid=21586511453&adgroupid=&keyword=&device=c&gad_source=4&gclid=CjwKCAiAk8G9BhA0EiwAOQxmfgMX85uQqnOZMAvCdYdmVo2krWNdqP1vCMUg88csETRoiRnmNA9iIxoCtbAQAvD_BwE

Day 3 - High Fever 🤒

Day 4 (16th Feb 2025) :

Total time 4 Hours!!! Started from 1 pm (No school!)

I had to research the skr board first because many pins are very confusing. I decided to go with the btt skr v1.4 board and I found this very useful link - Official site info

Surprisingly you also get a rubber duck! yay! Also THANKS A LOT to whoever made this video https://www.youtube.com/watch?v=hRpWtx3HCGM

It helped me choose the stepper motor drivers because I did know if I needed uart and what jumpers I needed to use on the board! This is very confusing. I am also using a touch screen - tft24

Now I have lots of things on my mind that I have to buy so I decided to start working with the bom sheet!

Here is the unfinished work of the spreadsheet: https://docs.google.com/spreadsheets/d/1NrEE28tm0ULvl5nzLH3Xo_gENOVdaQEKzp27CuxsBW8/edit?usp=sharing

Day 5 (17th Feb 2025) My High Fever 🤒 Still there :(

Total Time 2 Hours!!! Started From 2 pm

Started to update the BOM

Researched about the Bowden style extruder and where to buy them.

I will be using A V6 Hotend:

I will be using a dual-drive extruder:

Day 6 (18th Feb 2025) Fever 🤒 Still there :(

Total Time 1 Hours!!! Started From 2 pm

Added many things to the BOM! I found many cheaper sites so I had to update them all! Did many other stuff

Day 7 (19th Feb 2025) I am feeling better than before!

Total time 2 Hours!!! Started from 1 pm

Today I started working on the 3D model of my printer since I was bored to hell updating the BOM every day!

First, I needed to design the 4040 Extrusions! Luckily I found them on GrabCAD. Now I will make the Frame

Yeah, I had to watch so many tutorials and I was doing everything manually debugging a lot. Now I realize how bad I am :(. But I still made it!

Day 8 to 19 (20 to 13th March 2025) Sorry to lazy to write everything!

Total time 9.75 Hours !!! 45 mins Everyday (i had to make a routine bruh)

I worked on the cad files every day and since I am a noob in fusion it took me some time to make the final result of the frame with the heated!

I made this till now NOT DONE!

I will soon upload the newer cad file!

Day 21-34 (14th March to 27th March 2025)

Total time 28 hours 45 mins(i grinded)

Yo guys, wassup Ik i haven’t updated for a long time since my parents only gave me 45 minutes to work on this cause I have exams, and I am trying to finish everything before my main exams come!!!

SO THIS IS THE UPDATE! I added input shaping mounts for accelerometer! I havent built a printer so this is a big thing for me so In the last few days and these days I WATCHES VERY VIDEO on this series - https://youtube.com/playlist?list=PLP-VDZmS6bFo6qyPS8MyBFKqepQHpjCEB&si=mJB7cQvZAObcFmbE Because why not I am definetly usng this mainboard and since we ARE GOING to RMRRF which have people building cool stuff like 6 second nozzle changes even I wanted to ttry to implement something cool. Hence, I needed to know what my mainboard could do!

Now for the main updates i did today is I FINISHED THE Y AXIS (and i have become noob -> master in fusion 360) <- wow so cringe And Yeah i did everything manually I DINT even KNOW AALIGN TOOL EXISTED. I ALWAYS MANUALLY Made everything fit together. But now I am done with the y-axis. I promise everything will be faster from now on because I’m like 70% done less goo.

Here is a photo of what I finished

And also i have almost finished my shitty BOM here is a sneak peek: <img src=“https://hc-cdn.hel1.your-objectstorage.com/s/v3/f460a81e4a50cfa1f8710232cfcd2f73e88b81fe_image.png”

I don’t know but my fusion is definitely not organized, bruh :(

Thanks, ppl more updates soon! Sneak peak: working on a good PCB

Day 35 (28th March 2025)

Total time 4 Hours

Hi guys, I know i havent updated this for a while but I am:(drumroll)

working on my printer to be sci fi themed

99% DONE WITH MY CAD FILES I have started with my pcb for the neopixels and the bom please dont talk about it I Need too finishs the bom when i am done (it will be a pain)

Now for the pcb i am using klipper with Skr mini e3 v3 and neopixels I found this helpfull link which i might chekc out later on : https://www.reddit.com/r/klippers/comments/rdbmp2/klipper_neopixels_on_skr_e3_mini_v2_working_how/

I wanted to change colors like for heating: orange for error:red for printing:bluish pink and for leevling or any equipment test :green

I might add more later on like for moonraker timelapse each time it takes a photo the blush pink changes to white for a clear photo.

Here is my almost finished printer cad( i have to do the electronics storing base ):

I know it looks a bit ugly but after building its going to be 🔥

Thats all for today maybe tommorow and later on i will give more updates and phoos aobut the pcb since my exams are officially over.

Day 36 (29th March 2025)

Total time 4 Hours

Hi Ppl I have designed the first layout of my pcb and also learnt some kicad. I researched a lot on how to wire a capacitor but couldnt get any info for neopixels. So in this pcb v1 I have done everything without capacitor:

A reddit post for my capacitor thing: https://www.reddit.com/r/PCB/comments/1jo8qhs/soldering_neopixels_ws2812c_with_jlcpcbs_assembly/

Schematic

Footprint

A nice 3d model:

Thats all for today i will wait for a reply on reddit.

Day 36 (29th March 2025)

Total time 3 Hours

I have started working on a filament dryer mount for my printer which gets the filament directly from the dryer!!

I worked more on the Cad Files of printopus Here is my finished and updated pcb with some copper blocks and a capacitor which unfortunately i dont have a 3d of but you can see the pins:
