Hello. Any chance for E3d Volcano? Thank you so much

The macros included in the manual results in the commands ignoring any params given to them. For example, G28 Z should only home the Z axis, but will now always re-home all axes.

These updated macros should work better as it passes {rawparams} back to the base commands:

[gcode_macro BED_MESH_CALIBRATE]
rename_existing: BED_MESH_CALIBRATE_BASE
variable_probing:False

gcode:
  SET_GCODE_VARIABLE MACRO=BED_MESH_CALIBRATE VARIABLE=probing VALUE=True
  BED_MESH_CALIBRATE_BASE {rawparams}
  SET_GCODE_VARIABLE MACRO=BED_MESH_CALIBRATE VARIABLE=probing VALUE=False

[gcode_macro G28]
rename_existing: G0028
variable_homing:False

gcode:
  SET_GCODE_VARIABLE MACRO=G28 VARIABLE=homing VALUE=True
  G0028 {rawparams}
  SET_GCODE_VARIABLE MACRO=G28 VARIABLE=homing VALUE=False

Part has a section with a lack of material for printing with voron print specs, .2mm layer height. I checked the STL and even exported the STL from the CAD, both have the same issue.

The file only contains the Stealthburner cover, no mounting plate.

any ideas how to solve?

Hello everyone,

I'm new to the Voron community and now have a Trident with TAP. The Knomi is also new and installed successfully. Unfortunately I'm having two problems with the Knomi and I would be happy if someone could help me.

When I turn on the printer, the Knomi does not reconnect to the WiFi. Every time I have to press the boot button for 5 seconds and re-establish the connection. Then it runs until the next restart. Can anyone say what that could be?

After I inserted the "Knomi gecode macro" into the printer.cfg, additional homing is carried out. This happens at the beginning of the print job (it's normal) and the second time between "calibrating_z" and "BED_MESH_CALIBRATE". I think it has something to do with the G28 in the macro. Is anyone able to help me?

Thanks in advance!

I'd like to add a knot to each of my tools and show the temp of the tool it's attached to, is there a way to accomplish this easily? To T0 will show the temp for T0 and T1 will show the temp for T1 etc etc

I've got 2 KNOMI's which show no signs of power when connected via USB-C to either of two Win 11 laptops (and don't know up as ports in device manager, but do power up when connected via USB-C wall wart. The problem is that I'm looking to customize their firmware and see no way to do that. I have other ESP32 devices with power up and flash just fine from my laptop.

I've otherwise got a VS Code dev environment set up just fine for ESP32 devices on this laptop so I'm pretty stumped why the KNOMI's aren't working. Any ideas?

Are there any plans to add ota firmware updates in the future?

I cannot for the life of me get Knomi to work properly. Knomi is able to connect to my printer but it just stays on standby mode most of the time. The only thing I've been able to get working is homing after adding macro _KNOMI_STATUS per user Surio79 and flashing it per Cyanodil's post on the same thread. Probing is supposed to work with this macro but it doesn't for me. This is all on a Micron+. I rebooted the Knomi to work with my v2.4 and it works perfectly fine there, which is strange because I built the Micron+ using the same config files I used on the v2.4. I suspect it is a moonraker problem. Not sure this is related but for some reason, in fluidd, under the print jobs, there's no data listed for "Last printed" even though I've printed files before. This data does appear on my v2.4. Additionally, I've tried reflashing my CB1 with fresh version of klipper, as well as change my motherboard from manta m8p + cb1 to octopus max ez + pad7. Even tried a cb1 emmc with fresh klipper. Still no luck. After these changes, I still don't get any information under "Last printed". I've spent days trying to figure this out, I have 3 Knomis, none of which can connect to my Micron+, all of which can connect to my v2.4. I'm about to try a completely customized UI but I'd thought I'd try my luck here before doing that.

Any bright minds out there have any idea wtf is going on?

Is there a version for use with the Knomi 2 and 3do 4k Nozzle cam?

Hello BTT,
I'm working on bringing V2 into the Ender/Sprite Extruder world of 3D printing as part of the Taurus project, but would need a step file of the board as you had released in V1 already. Is that possible short term?
Shown is an early prototype of a new case for this application.
Thank you.

i try to flash but not work

Hello,

I have the problem that the Knomi 2 don't save the wifinetwork. After reboot comes the Hello logo back. I change the ssid length but thats not helping. He only save the Ip from klipper.

The other problem is that Knomi says the printer is not opartional. When i reboot klipper you can see that Knomi have connection and show the reboot animation, but after thsn nothing. I have a Sonic Pad.

Hi BTT

1. Copying the PDF macro content directly from the PDF does not work because all formatting content is lost and Klipper fails to boot due to parsing errors. The gcode lines need indenting to stop the parsing issue.
2. After including the Knomi Macros Print_Start fails with a repeated homing error stating Macro G28 called recursively (3 times).

Please advise and thanks Boothy

Hello, I would like to submit some changes to the knomi source tree. Or at least fork it.
Some of my changes were well received by the community so I would like to share this work.

Unfortunately, due to my current job, I'm constrained to only submit/fork a project if it's license is explicitly public. The knomi project doesn't include any licensing so it is all rights reserved by default. It would be nice for the community and the product itself to have this project fully open source (probably including the square line studio project as well) as it would allow a larger adoption and use cases from the community.
I won't request any specific licensing, but defining a clear one would be nice to understand if the lack of it is just an oversight or the company actually wants to keep ownership (which I respect as well). That would at least clarify the situation and avoid confusion for people like me that would like to tweak the product and share without fear of potential problems.

Thanks in advance.

Hello,

Could you add the .STEP file of the mounting plate Knomi V2 please ?
We only have the .STL file.

Thank you

I changed the UI Colour to Green, but the standby page remains default.
Is this normal?

Confirmed, Wi-Fi password is not retained after power is removed

Where is the sty for the mounting plate?

Is it possible to install on ESP32-C3-Mini-1U?

The IP address field only allows for 16 characters. This does not allow for a port specification which is necessary for multiple printer Klipper configurations as well as for the Creality K1. The device cannot be used for these printers.

I, for instance, have three printers connected to two Klipper hosts, and a Creality K1 Max. I cannot use Knomi V2.0 with three of these printers.

Note that Knomi V1.0 allowed the port specification, so this should be considered a regression.

Thank you for your consideration. I'm keen to make use of Knomi V2.0!

It's impossible for me to flash Knomi. I have tested on MacOS and Windows, same issue.

Serial Console detect Knomi but impossible to flash it :

It's really annoying that the knomi doesn't properly implement USB-C.

It can't be powered by either PD compliant USB-C chargers (which pretty much all new ones are nowadays), nor when plugged into a Macbook with a straight USB-C <-> USB-C cable...

Homing only one axis, homes all of them. Not work either clicking in Webui or issuing command in console

When multiple networks are present, Knomi V2 onboarding works and connects to the specified network after 1st restart.
After 1st power cycle, it goes back to onboarding screen and we have to enter the WiFi password again. This repeats itself.
Each time this is done, a new network entry is added to the WiFi networks table.

If this is the wrong repository, please indicate where the correct one is for Knomi V2.

Since the V1 display isnt a touchscreen, how do I use the color changing wheel?
I have tried changing the default color in the firmware in the config.h file, but that seems to break the device upon flashing so that I can no longer successfully put my Moonraker IP in the webinterface without it replacing it in the text field with random errors.

I have installed Knomi 2 on my Voron 2.4.
When running print the x any are showing some "reasonable" acceleration bar, the z bar is nailed to the top the most time, and sometimes s just drops 1-2 bars below max.

Is this a mechanical issue with the part cooling fan, of the hot end fan?

Not a problem with KNOMI itself but a problem with the GIF file subblied by BigTreeTech.

The GIF for leveling in the ZIP file is not the same as the one used in the original firmware.

The one in the firmware is a hotend going up an down, the onr in the ZIP file is like the circles that would be created by throwing a rock in water.

I've searched and could not find the original leveling GIF used by BTT.

Would it be possible to get a copy of the original leveling GIF.

Thanks,

I'm hoping it might be possible to set the display to rotate 180°? This would allow for additional mounting options with the USB port at the top instead of the bottom. Is this possible?

With the Knomi 2, if the ambient room temp is for example 19 degrees C and you swipe to the preheat screen and press the button to preheat the bed, then press the check button while the setting is above 0 but below the ambient room temp, the Knomi 2 will be stuck on the preheating screen with no way to swipe out. The only way to recover is to use some other control interface of the printer and turn the heaters off.

Manual flawed at pages 9, 10, 11
Expirienced the consequences 1st hand. Was not paying attention and destroyed my canbus board and the toolboard.

here is the problem:

the manual even shows you the consequence

Would it be possible for an alternate "Main Body" file to be published for the Rapido UHF? The official Stealthburner mod is located here: https://mods.vorondesign.com/detail/XN1NolgVYYBu1HNnxqC7Fg

I have my LAN set up to use IP addresses from 10.0.0.1/16 subnet, but when I enter AP settings, serial console shows that KNOMI uses IP 192.168.1.123 and then I can neither open settings page, nor it can connect to moonraker.

As the title says after I uploaded compiled code via VSCode to a Knomi the animated Voronlogo/Emotes have very bad low fps. Maybe there are some settings missing in the firmware.

Mainsail and klipperscreen gives a lower percentage of the print than KNOMI.

I was working on bringing Knomi V1 into the ender world on top of the wildly successful Taurus cooling duct.
This was days from release when Knomi V2 suddenly came out.
To make an enclosure for V2, I will need more information so I'm looking for the open source repository that was advertised, but all links I can find still go to the V1 repo. Where is it?

Hello,

The mounting plate is not anymore in the STL here :

https://github.com/bigtreetech/KNOMI/blob/master/Customized%20Printed%20Parts/Mounting%20Plate%20%26%20StealthBurner%20Main%20Body%20for%20KNOMI.STL

After finally getting the knomi to work as intended, my last issue is that the code disables KAMP. KAMP renames bed_mesh_calibrate to _bed_mesh_calibrate. Wondering if knomi renaming it to bed_mesh_calibrate_base is the issue. The Kamp.cfg is read only so not sure what to look at. Thanks!

What is problem ?

sup guys i have the KNOMI already flashed, ready for wifi connection... my issue is when i connect my pc or phone to the knomi wifi network it then opens up a msn page, it doesnt take me to the knomi wifi page to link it to my network? anyone had this kind of issue?

There are no .bin files on the firmware page and Visual Studio doesn't show any files that it can open.
I'm obviously missing something

Is there any chance to get the original animated Gif-Files ? I want to recolour them for other coloured Printheads.

I tryed the methode that the other person had and others tryed but they had no effect i cant get vs to flash firmware to my knomi it gets detected and everything by vs but the flashing will not work

In the Knomi 1 manual there are instructions to customise the animations – this is a great feature. Is this still possible in Knomi 2? there's no mention of it that I could find.

Hi, My KNOMI screen just turns off. Sometimes it won't even startup (You can see it's powerd because screen lights up) and other times it starts and half way a print it turns blank. I tried using different voltages to power the KNOMI everytime the same thing. Any suggestions?

The bug

The G28 commands can take the axes to home as arguments.

The macro in the KNOMI documentation will not pass those arguments to the original macro as-is, and will instead transform any homing commands into a full printer homing command.

How to test

Without using the KNOMI macros, run the following gcode from the console:

G28 X

It only homes the X axis. If you install the KNOMI macros, it will instead home the full printer.

How to fix

To preserve the behavior prior to KNOMI installation, the macro needs to pass those arguments back to the original.

I propose to use Klipper's rawparams feature to fix this thusly:

[gcode_macro G28]
rename_existing: G0028
variable_homing:False

gcode:
  SET_GCODE_VARIABLE MACRO=G28 VARIABLE=homing VALUE=True
  G0028 {rawparams}
  SET_GCODE_VARIABLE MACRO=G28 VARIABLE=homing VALUE=False

Config from the manual added them corrected because it did not copy and paste correctly. Homing icon works correctly. While Gantry level the homeing Icon displays. While mesh bed leveling the home icon displays. After the bed mesh completes, the screen status icon displays 2% while the heater heats to temperature and I receive a message in Klipper "SET_GODE not valid command". Then as the print starts the screen displays 3% and increases as print progresses. Hopefully when this issue is solved the it will work with KAMP bed mesh leveling.

Is there any way to use OV2640 interface? kinomi 2 was advertised to be able to use camera and humidity sensor
currently software doesn't take advantage of that
