Hi,

I want to install the RPi 3 Model B+, but its seems the bins are covered. Is there a reason for that?

It was hard to remove, 

Please help

You are a new member, so I will give advice I would not to someone with more kilometers of filament under their belt.

Don't use a Pi Zero - no matter what Prusa says. (I know you are not - this is just a reminder).

Don't use the GPIO pins for your Pi.

Don't source power for your Pi from the Einsy.

I am very happy with my home for my Pi 3B+. A separate enclosure that houses both the Pi and a buck converter (cheap) run off the PSU. Mounts on the MK3S frame.

A short USB cable that runs to the USB input on the EINSY.

Of course a Pi Camera to keep track of all the action.

You will be very happy with OctoPrint on your Pi 3B+. And feel free to ignore my advice. It is only advice.

Thank you for your advice, I'm using OctoPrint and RPi 3+ with external power for the RPi for more than 2 years now and I'm happy with it.

I just want to reduce the wires on my desktop and rearranging everything again. After researching a lot on the internet I found that people are connecting directly from the Einsy board for powering the RPi. So I thought that's a good idea to implement it now.

You havent mentioned why you dont recommend doing it? is there any reason I  should know?

 

Thanks

Bah - your new member status does not reflect new user. You know what you are doing.

GPIO pins are problematic. A short between pins there will destroy the EINSY.

The EINSY can not supply enough power for the PI 3.

Data buffering from the GPIO appears to be more problematic in the GPIO interface. USB is hardware buffered, which seems to give fewer problems with under-runs and missed layers.

That EINSY enclosure is just plain crowded. Barely room for the Pi Zero. 

That about covers it for my biases. Good luck with it!

I just learned via customer service chat that if the sticker is removed, the board will not be covered by warranty. Makes it a simple decision for me. I'll probably end up buying a short usb cable

The USB cable I am using is about 6 inches. My Pi case is mounted on the frame directly above the Einsy.

Another discussion on this sites here: https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-user-mods-octoprint-enclosures-nozzles-.../octoprint-with-raspberry-pi3-b-usb-vs-gpio-connection/

I'm using an external powerunit for my Pi3B+ (5.2V/3A) and connected (datalines) to the Einsy over GPIO with a flat ribbon cable. I also set baudrate in Octoprint and FW to 250000. Working since the beginning in 2018 without any problems (connected 4 USB devices (2 cams) and a Waveshare 7" Touchscreen).

Eh?  That sticker is called a "pick-n-place pad" - a piece of polyimide film.  It's just a spot for the vacuum nozzle on the robotic assembler to grab the connector to put it on the board.  It's intended to be removed after board is soldered.  Normally it's just peeled off later in the manufacturing flow, as the connector can't be used with it in place.

CS may have been thinking of a different sticker somewhere else.
