When I try the nodejs "Headless conversion" with
node ./mbc-node.js out.png 0.mbp
I get this output:
convert out.png to 0.mbp
mb init ready
mbc conv: [
'120', '130',
'40', '-i0',
'-o0', '-w0',
'-s2'
]
mbc:p0
mbc:p1
mbc:p2
mbc:p3
mbc:p4
mbc width: 1118
mbc:done
convert done, saving to file...

But PrinCube wont accept the .mbd file and says "Format error" when trying to upload via the Web-interface.
Looking at the generated file "0.mbd" in a HEX editor:
MBrush,null,null,null...

Files generated and exported from PrinCube start with two HEX bytes followed by the word "files"
What have I missed or doing wrong?

And why does the documentation refer to ".mbd" files and the Web-UI uses ".mbp" files?

APP Version 4.33
FW Version 4.16/s2

I'm trying to get my MBrush working. I can connect over WiFi. I can see it cycling between the two test print areas when I press the button. It beeps like it's printing when I move it and lights are green for the duration of the "print".

However no ink comes out.

The device was left for a while without use.

I've used water with a light soak to get the ink flowing. I see a nice C&M with a tissue blotting but Y is not flowing very well. But I expect I should still see something printing.

I think we got something printing out of the device when we first tried it but nothing since.

I've updated the firmware to APP 4.36, FW 4.17. I've power cycled.

I've read through the FAQ to no avail.

I'm not sure what else to try.

Really want to get this working again for my father. He's actually one of the original inventors of the technology in these cartridges! (Yes, he regrets how the business ended up and never saw a penny from their current bs practices)

Unboxed the printer last night and today it only prints in colour - nothing black at all.
Replaced cartridge with another and still the same

Thank you for your work!
In settings there are switches for cartridge color order and head width, so one could guess that printer is compatible with more than one family of cartridges, but no mention anywhere in docs.

What are the compatible models?
Which cartridge are you using in your demo video?

Hi,
Where can we download the firmware binary ?
Thanks,

I want to replace the mouse sensor signal with an external displacement signal. So I want to know the model of the mouse sensor on the PCB.

Hi,
Just a quick question: what cartridges can I use?
I know about ho 62xl, but don't know if any other tricolor cartidge would suit. Like for example 62 (not XL) or any other numbers.

Another thing I wanted to ask is about the app. Last year I read in some thread that in a few months there would be an app, but I can't find it. Does the app exist?

Thank you so much in advance

With reference to the following thread "User fonts not worked #10" I am having the exact same problems. So I was wondering if this problem has been fixed yet. If so what do I have to do as I am a newbie on here as this is the first issue I have found with my trusted little mb printer.

Basically can load font files and set up text with chosen font but once I save, font reverts back to default

I have checked the firmware and I am running the newest one as you are also listing on here FW 4.16/s2.

I mainly use my printer on usb cable connected to win 10 and I use the web interface on Chrome

Thanks for any help

Hi. I'm not sure if this is possible but is there a way that the conversion process for the image slices can be sped up at all? We are using the printers in a large installation with many thousands of images and conversion time is around 15seconds for three slices. I've tried to pick apart the code that converts but it is a little opaque to me. If there is no way to speed it up programmatically, are there contributing factors that cause the conversion to take more or less time?

Thanks.

I have print color issues when i'm waiting 20 seconds or more between two prints.
See pacman pictures attached.

If I do prints consecutively ( no delay between prints), it works great.

Is this normal or my mBrush is faulted ?

Is there a way to fix this issue ?

Thank you very much for your help.

I don't understand why the Wifi of my PrinCube keeps saying Wrong Password with both iPhone and Android. I proceeded to upgrade the firmware version PrinCube-fw-4.26_4.11.tar but the same problem occurs. It only works with the PC but there is no way to connect the wifi to the phone.

I'm waiting for your answer

When I click the export function from a device (I tested IOS and PC) I can not export a saved job/template.

Hello!
Our organization wants to use your printer in its program. Is it possible to print text from our program without creating a project? For example: print ("My text").
Or maybe you can write text to the label in the finished project and send the project to print?

Guys,

I'm glad you're actively working on the firmware and software for the cube.

Any chance of better instructions on how to use the product though? Yes I can bash my way through using it, but the YouTube videos are getting a bit long in the tooth and the UI is a little confusing...

Don't be discouraged though, I thank you and the team for your efforts!

My request list is as follows:

User Requests

• New YouTube videos on how to use the product, more in depth

• iOS or Android Native Apps

• Full End user Manual

• How to properly clean, and care for the product

I mean is there a configuration for set_wifi which allows to connect to an existing wifi? This would allow devices to keep using the internet while accessing the printer easily.

Has anyone tested the tricolor cartridge for the 803 model? It seems the colors are on the same sides although have bit found any substantial information.

Hello,

I try to connect my Mbrush to my Android Samsung 9 plus device, and even if it manage to connect via WIFI the application can not connect to the printer.
With ver 4.11 I manage to connect sometimes but not all the time.
On Ver 4,15 it can not connect at all.
Om my old other device that I have LG Android it connect with no problem all the time.
My Sumsung can see the MBrush WIFI and try to connect, but with no sucess.
Please advise if you have any suggestion what should I do to connect the Sumsung, since for now I keep my old LG device just so that I can use the printer with WIFI?
Thank you

Hi there my printer stopped working after updating firmware

I already tried the USB cloner but I don't know what to do and what files need to be placed where

Please help me

Hello, I've just got my PrinCube, and tried to test it with default images. But the ink seems pushed wrong and there are some color drops, and also yellow color is not printed fully. I've downloaded latest firmware but issue is still there. I don't know is it hardware wise or not.

In August when I tested my mprinter it worked. And now, the page APP that lets me enter in the text/picture to the printer doesn't work so I can't use my printer. HELP! I am not good with understanding what is going on so please simplify. I tried resetting my router, had family in other states try but don't think it works in America. What is going on? HELP.

I'm trying to use a custom font. For example: https://www.fonts-online.ru/fonts/cyrillic
It show my font correct on text edit box. But after finish editing text changed to default font.
Next. After upload my fonts only presented while I'm editing. After quit and start a new edit my fonts disappeared.

I see the "pos_dat" file, what does it do?

Man, I am developer and I really don't understand how to update the firmware.
I followed all the instructions you posted on the github issues but......nope it doesn't work.
it seems my mbrush is updating and restarting after using the cloner-2.5.8-ubuntu_alpha and the image generated by the tools/release_fw.sh
but my phone couldn't connect to it.
I have tried different combinations of files in the USBCloner/config/POLICY but no way.....
I am close to send the device back so....
Could you post a video tutorial quickly before I become nervous using this device and throw it away?

I've been having issues recently. The princube won't start properly (white led no beep).

Is there a hardware issue with my princube or am I doing things wrong?

I tried the factory reset by holding the button for 5 seconds but nothing happens.
Is there a way to do a hard reset of the hardware?

Thanks for your help, sorry if it's the wrong way to reach help.
I couldn't get help from the support of TheGodThings so far.

Hi Team - I have the issue with my MbRush printer.

The printer does not start properly. It suspends at the start level. After switching in on - both lights flash white, while it should stop to blink after 5 seconds and turn green to be ready to print. I've checked google and YouTube for the troubleshooting, same as hints form the producer (incl. reset of the device) and nothing.

I've tested it with two different ink cartridges. I've checked it with the USB cable (connected to both - Linux and Windows PC) and with WiFi on Android. The WIFI network could not be found (as the printer does not start properly).

Geekbuyng advised me to flash the firmware - but the device is not recognizable by my Windows or Linux.

Movie (.zip) attached.
printer_AND_H.mp4.zip

Can You please advice?

And where can I find the tutorial on how to flash the FW? I'm not an expert in this area and some tutorials would be very helpful.

Thank You in advance Guys!!!

Hello, I'd love to buy a PrintCube. I absolutely love your support and that you have open sourced the code.

Is this the legit site to buy it from? https://www.thegodthings.com

Hi,
I bought a black and white cartridge hp62xl but seems to be not recognized. Can u help?

Great to see the PrinCube code is open-sourced,

it will be nice if you can provide a basic build / flash instruction, so more people can help.

There is no internet connection when selecting MBrush wifi. Could you please help me to solve this issue?

printf("Access-Control-Allow-Origin: *\n");
might be enough to add after setcontenttype cause the qdecode doesn't seem to have a add_header method or such.

I tried mips compiler form ubuntu, yielding:

originial file output
ELF 32-bit LSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), dynamically linked, interpreter /lib/ld.so.1, for GNU/Linux 2.6.32, with debug_info, not stripped
new file output
ELF 32-bit MSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), dynamically linked, interpreter /lib/ld.so.1, BuildID[sha1]=98439f67c2ea9cbf6087a1a73182af3df3a4880a, for GNU/Linux 3.2.0, with debug_info, not stripped

but looks like its for newer gnu linux version ?
Result is '404 not found' using the cmd= to run it it yields syntax error ( or such (?) wheras the original just says status err filename ro length empty as expected.

Is there any hint about how to setup this cross compilation toolchain ?

Can you please share some knowledge about technologies involved in printing cartridges?

I know hp cartridge uses thermal bubble inkjet technology, epson ones uses thin-film piezo technologies. The first are compatible only with water based inks, the latter also with pigment inks because they don't warn the ink (afaik). Hp has developed the latex ink that has properties similar with pigment inks but can be used with hp cartridge (but it is not known if they are compatible with all of them).
So as for your experience, can you write down a summary of what ink can be used with the hp62xp cartridge and what characteristics the ink mush have? Kind of interesting.
Thank you.

Hi,
Were are the documentation about requirements to upload image in the Princube ? We don't know how to create correct format (transparency, etc...).
Thanks,

Got my PrinCube today and ran over the issue that when using Chrome, no project ist shown on the main page.
With eg Firefox it works fine.

Can the firmware be modified so that the printer can select from multiple images ? Eg pressing the button twice meaning the upload before the previous one or moving the sensor 1cm into the wrong direction meaning previous upload, 2cm the one before the previous upload ?

When attempting to upload a release ive built myself (Windows or Linux)
I am faced with

No matter what i try doing, downgrading the MBrush using the cloner and then updating.
It seems i simply cannot upload it.

Any advice would be of great use.

Hello! I want to increase the ink-jet volume of MBrush so that the ink can pass through an ordinary A4 paper, I have adjusted the parameters of the machine to the maximum, I think I can only modify the machine code, I hope to get some help.

MBrush only prints half a line. Consistently good, but only a half of it. See fig. 1.

Can anything be done?

Thank you for open-sourcing PrinCube app!
Will you add Japanese translation if I translate
mb_ser/js/utils/lang.js ?
It will be more useful for Japanese people.

I cant install the usb driver, win 64 bit says it isnt a right driver.

How can i install the usb driver? Windows says the driver ist not the right one.

WE have received a new Mbrush cube, which worked fine for a few minutes (maybe 1 hour) a then suddenly stopped. When the button is pressed two short beeps are heard, LEDs turn green but then nothing happens - while moving in either direction, the green LEDs just stay ON. They change back to white after some time (
It looks like the cube is not detecting any movement (maybe?)
The optical sensor is not obstructed, it actually emits light (we checked with a camera)
The wifi and web interface work, we even tried reflashing the FW (4.33 / 4.16) but it didn't help.
What can we do to identify the problem and fix it? Thanks

hello, I received today my MBrush and everything has benn looking and running good until the first print! There are several mistakes in the print output, see attached. I have been cleaning the nozzle and also updating the firmware but nothing helped! Can you help me? Otherwise I have to send back the MBrush which would make me very sad!

THX & BR Peter

mBrush smears yellow and green color before printing the photo, which is also smeared looking and very light in color

My printer does not print.
At first I didn’t print correctly,the colors were wrong.
And then completely stopped typing.
Please Halp me...
