Project 24: Voron 2.4 300mm 'Knuba 3Dubba' - Siboor Aug 2023 Cartographer Kit

[Manux]

First round of calibration

I'm quite happy with these results. Did Elis Guide and the Calibration prints from Orcaslicer.

Still to go Input Shaper and VFAs testprints. 

There is some buildup of filament on the cube but im not sure where it could be from. TOP looks marvelous.

I also did the MAX Flow test and the Dragon HF Hotend with a result of 20 with a CHT Nozzle. 

Here are some pics, This is more voron like

Found the Source of the Blobs

I found the source of the blobs nozzle was not tightened enough...

Fixed it up and no redoing Carthographer Calibration

BlazeCut fire supression

I mounted the Blazecut fire suppression tube near the mains with the Omron relay, PSU main and Octopuss mains. I think that a good location.

I secured it with a zip tie to another zip tie that is mounted on the PSU.

Hope i never need it!

Hotend Serviceability

Others will know it but i had to service the Hotend, because i did not tighten the nozzle fully. 

The SB Hotend is quite easy to service, 6 screws its all it took i would say that is Prusa MK3/MK4 level of servicing.

In the end nothing was wrong the problem is with the Dragon HF Hotend. The opening is not like a funnel but just a hole. So the filament has difficulty entering. I should have used a drill to make it better but i could not be bothered this time..

If you are reading this before building make sure to drill the hole a bit of the heatsink tower to have easier filament loading.

Printer notifications

While i was tuneing my filament loading and unloading macro it became apparent that i needed a beep sound to notify me to load the filament or remove it.

While i was looking for that i discovered something amazing! Siboor did not just include a beeper in the kit. Its a (cheap) full blown speaker.

This allows me to do stuff like this:

 

To get that do the following:

#!/bin/bash
# Play startup sound after Klipper startup

sleep 5
aplay -D plughw:0,0 /home/biqu/printer_data/sound/klipper_start.wav

Save as:

/usr/local/bin/klipper-start-sound.sh

Make executable:

sudo chmod +x /usr/local/bin/klipper-start-sound.sh

Then create a systemd override:

sudo systemctl edit klipper

Add:

[Service]
ExecStartPost=/usr/local/bin/klipper-start-sound.sh

 

But  better yet with kaiuh.sh i was able to install Gcode Commands and now i can send voice notifications when certain events happen.

What kind of wav do you need:

 

1.4 Second Silence Before Speech so speaker can wake up (did i mention its a cheap one...)

WAVE audio, Microsoft WAV, Signed 16 bit PCM, mono 48000 Hz

install G-Code-Extension to execute commands:

~/kiauh/kiauh.sh -> Press this: E , 1 , 1 N

 

Now your gcode Macros can do sounds like this:

[gcode_shell_command sound_primeing_cmd]
command: aplay -D plughw:0,0 /home/biqu/printer_data/sound/Primeing.wav
timeout: 5.
verbose: True

[gcode_macro SOUND_PRIMEING]
gcode:
    RUN_SHELL_COMMAND CMD=sound_primeing_cmd

 

Here is my macro config and some of the wav files (you can use your LMM of choice of course... just make sure to add 1.5 second silence at the start)

my_gcodes_sound.cfg

 

 

Happy Printing...

More Calibration

I found these helpful for more calibration of my Sunlu PETG filament:

Speed gains

Here is my old Prusa MK 3.5 vs the Siboor:

Prusa:

Siboor:

A solid improvment!

 Same model and Infill of course.

Tolerances

The tolerances are fucking amazing! This just fits.

On my Prusa i had 0.1 to 0.2 depending on filament which meant i had to calculate this into my designs from the start.

This is just amazing

[Manux]

Side Panels

I mounted the side panels with Annex clips. I use 3.5mm Annex clips for 3mm panel and 1mm soft strip.

Sadly Siboor delivered strip was not long enough.. But i had some tape laying around...

LED Show

I installed

Works like a charm.

Here is my print start macro:

Reliability

I printed 43 STL so far mostly voron Test cubes. The quality is there. But i fucked um some slicer settings so it does not look like it could so im not sharing right now but i seen enough to say its the best print quality i ever seen. Its on par with Prusa MK4. With more tuning time it could surpass this as well i think. And this with 50% print time than the Prusa MK3.5s.

Of those 43 STLs/Prints i did not start at two or three times with Communication error while Bed Leveling. I Hope i mitigated this with some Gcode tricks. We will see.

One time it did layer shift but that was my fault. 

All in all I'm quite happy with the reliability i had ti tinker way worse with my Prusa MK3.5s to get it to the workhorse it is right now.

Blazecut 2 installed

Second one installed on top of chamber. I used hot glue to seal the holes.

[Manux]

Octoprint Everywhere

I setup octoprint everywhere as it is free and has AI print failure detection. I quite like it as it is also working together with Mobileraker and i can watch my prints on the go with this.

[Manux]

More Sensors

I has two sendors laying around from my prusa modding so i used them on the voron. One near the intake fans for room temp and the other on the blasecut tube to messure heat in the electronics bay.

I used the standard octopus thermistor plugs for it.

Room temp sensor suspended in the intake air flow.

Plugged in to the octopuss board.

Camera

At the moment i'm working on a cam mod for the Logitech 920 mount.

I want it on the front 2020 extrusion and i got a holder jerry rigged but i will post more when i get there....
