    Post CubePro Cartridge Recharge Options

    I am aware that there is a hack for CubePro v2.00.
    If you want to use the latest version of CubePro, you will need to buy new cartridges or reset the chip.
    Good news, resetting the chip is becoming simpler! This is all possible from the efforts of Tomuro (

    Tomuro released code that will recharge your CubePro cartridges to any amount. On the surface, it can look daunting.
    After a significant effort, it turns out it can be as simple as 2 components and minimal learning, all of which is outlined here in this series of posts.

    I am not going to rehash everything here, but I thought I'd post a digest.

    First of all let me state this: You can reset your cartridge chips for as little as $3/USD. That is a huge statement and I will stand by it.
    However, the initial intent for ReCube light was to be a one-touch recharge device for Cube3, Ekocycle, CubePro, and CubeX.
    This option can be had for under $30 plus shipping.

    Now that you understand the price range, you will realize that this is cheap compared to new cartridges or for simply finishing off your old cartridges.

    Of course, there is the F/W 'update' for V2.00. That is free. But it is a lower level release. How much is getting the latest F/W worth to you?

    "$3?" you ask?

    Yep, $3 and up to 30 days for delivery, you will have the ability to assemble, program, and use your cartridge reset tool.

    What's required?
    a) Windows as best I can tell. This is to load Arduino IDE and run the ReCube Light V2 installation batch file to install the program on the device.
    b) An Arduino NANO priced anywhere from $2 to $20. I can buy one today for under $3 and wait up to 30 days for delivery.
    c) Any one of many form-factor 2.2K resistor. 1/4 watt is quite common. You can scavenge one from junk electronics or just buy one.

    Can you solder?

    Simple assembly; make contacts.

    Solder the 2.2K resistor between +5V, pin 4, and pin 12 (A0). This is a pull-up voltage for the analog pin 0.
    Connect pin 7 to ground with a wire. This makes sure the auto-charge function is disabled.
    Connect a contact for the chip's short pad to A0 (pin 12). Connect ground to a contact for the long pad on the chip.

    This is all that is required for the hardware.

    I use Arduino IDE to test communications to the NANO device. This is simply to understand that the device is working.
    I recently learned there is good reason to do this. You will need Arduino IDE later anyway to operate the ReCube device.
    What you want to learn is the installed "bootloader". This matters for loading ReCube onto the device.
    Most Chinese NANO devices use an old bootloader. But that is not a guarantee.

    Load the ReCube Light code onto the Nano. There is a batch file included in the ReCube Light V2 download.
    It is basically a command line for AVRDUDE to install the program.
    You will need to make a few adjustments with a text editor (notepad).
    Note your device COM port when you are in Arduino IDE... Also note the bootloader you needed to upload a test program.
    For old bootloaders; use baud 57600 as provided; for current bootloader, use 115200 in the batch file.
    Also confirm all the folders noted in the command line! Bottom line; make sense of the batch file command line for your situation.
    Consider adding a new line to the batch file "pause". This will hold the result screen open to confirm proper loading of the Nano.

    Assuming all went well during the install, you are ready to see your good works on the screen.
    Connect you NANO to the computer; boot up Arduino IDE.
    Under tools, open the Serial communications windows.
    This opening of the serial communications port initiates a menu screen from the ReCube code.
    Type "0;<Enter>"... and the screen refreshes.

    Now connect the chip you want to recharge (imagination may be required here!). I have loose chips and some probe leads that do the trick in a pinch.
    Now type "7;<Enter>" and you will read the current chip fill status. The reply should come back 7,0,<whatever fill value is>.
    The 0 (zero) is an acknowledgement that the chip was read and not simply an error response.
    Assuming all is still functioning as set up; now type "8,50; 7;<Enter>"
    The "8" charges your cartridge to 50%... and you requested a re-read of the current percentage. The reply will be 7,0,50.

    From here, there are a lot of other functions... and know that you do not have access to advanced functions unless or until you upgrade to the Pro version. Contact Tomuro directly for this premium upgrade.

    A simple command line to interrogate your chip; 1; 3; 4; 5; 7;<Enter>

    This is probably the most simple yet complete overview of the ReCube Light offering provided by Tomuro at
    I've simplified all this by making a tool and offered it up on eBay.
    I will try to keep ReCube Light Cartridge Recharge Wands available for those who need solutions rather than more projects.
    Sub-components will also be available upon request.
    At $1/hr, I'm really not doing this for the money!
    This is about keeping these printers printing rather than clogging landfills.
    Feel free to ask questions or request clarifications.
