Yeah https://help.prusa3d.com/article/gpio-module_734695 unfortunately English and German versions are truncated, it was reported before few weeks ago.

Switch to Polish version and use for.example translate.google.com

Or try another languages.

Dear all, what you're proposing is more or less interesting, but in the whole cases means you need to add an I2c interface card, and that could be great if you are thinking about to control a lot of signals, but suppose you want to handle a single pin or as much as a couple of pins, I want to control a light while printing, and may be a relay to cut the power down ate print end, I think I have enough single pins in Einsy Rambo board, I mean the MMU ones, for example, my intention is to use one of those pins and simply connect a mosfet board, controlling this way, again, the light, does the system allow me to send a gcode to switch or on off the aforementioned pin?, could I use M42, or may be M226 if I need to read it, instead to write it?, this is my concern, will M42 work?, no interface, but the mosfet, no anything more only M42, will it work?, for me, that's the question.

As of 2025-4-6 the article in English seems to be cut short as the Polish version has more content. Seems like something has gone wrong. Please check?

Hi,

We've created an article about the GPIO board, complete with examples. We'll be adding more examples to the article in the future.

If you have any questions, feel free to ask them here or in the comments section of the article.

Link to the article

We look forward to seeing your GPIO-based projects!

Happy printing and hacking!

So basically Prusa is selling unsupported hardware because the latest officially supported version is 6.1.4

M262 sets the pin mode to input or output

M262 P6 B0 - Configures pin 6 as an output pin

M268 reads the registers of the IO device

You need firmware 6.2.0-alpha1 or newer.

The gcodes M262-M268 get me echo:Unknown command:

Prusa support told me those codes M262 and M268 are not listed among the compatible codes. https://help.prusa3d.com/article/buddy-firmware-specific-g-code-commands_633112

So, how are you using gpio without them?

Thanks for this! Ordered my board and now I have to wait for it to show up... :)

Could you perhaps add an example of how to wire a button to input on the hacker board to control an output pin? Is this possible? Would like to do this to control some enclosure lights/fans via button.

Thanks for replying! I must have missed the M261. Sorry about that. Can you explain the reasoning for not mentioning/documenting M260? I'm guessing to limit the liability for someone doing something dumb with that command.
