In Make magazine a big text about new berry http://makezine.com/2016/02/28/meet-the ... erry-pi-3/
Very nice update! And its backward compatible and 64 bit at the same time!

64 bits with 1GB of RAM is not per say a huge step forward, but yes with all other things this is nice news.

Need to think about driving both printers with only one RPI :)

True, but whatever they would have released...we would have wanted more :lol:

Oh, no rocket science here...

I am just using a Pi with OctoPrint. It is much easier than playing with SD cards and I can monitor the printer from everywhere.
You can easily run multiple instances of OctoPrint, as long as you use different ports.

My main issue is actually my old UMO: I still have an 1.5.3 board and I need to provide 5V from the USB. If I connect the USB it will draw current from the PI (which can be OK), but it will stay on all the time...
... and if I need to change the board, maybe I'm better with an UltiBoard 2. Need to bite the bullet one day for that one...

I think Amedee, needs to do a little piece on attaching the Pi to the UM, UM2 etc. With photos as well

I'll put that on the list and will ask the bear to take some pictures ;)

And OctoPrint works fine? I got the impression from UM-forum that printing over USB doesn't work so well and wasn't really supported by UM.

Perfectly well, I haven't used anything else on my UMO+ over at least one year...

The very first model B was not that fast, and hi resolution prints could suffer a bit (huge number of GCode to send for very small movements), but since the B+ it is all good.

There are some caveats with the UM2 because of the profile stuff which relies on 'UlitGCode' that OctoPrint can't handle. But if you ask Cura to generate standard RepRap GCode, you are all good (but you loose the profiles).

Ok, sounds good. I have a B+ in my drawer that wants something to do :)

The thing with the profiles and the fact that OctoPrint screwed up a print or two when it was trying to connect to the printer while it was printing from the SD card where the reason why I gave up on using it with my UM2.
I would like to keep the possibility to print from SD card and would use it mainly for monitoring the progress of these prints but that doesn't work. If the print is started from SD, you can't monitor the progress from OctoPrint anymore as it can't "attach" to the printer while it is working.

Right, it is the one or the other.

For the printer, printing from SD or from USB is a totally different process, so you cannot suddently decide to send a pause from USB while printing for SD.
Also when the line is opened (through USB), the Arduino board will reset. It is the way Arduino works and there is nothing you can do from the software side.

OctoPrint is a (very nice) alternative to other USB printing software (like Cura, Repetier Host, ...) and like these it replaces the controller.

If you just want a monitoring solution for SD card printing OctoPrint won't help, just use a webcam, you can then possibly use a berry to remotely switch the power off or connect a gpio pin to the UltiBoard and trigger an event (custom firmware required ;) )

I have used a webcam in the past but I am still missing the information from the progress bar on the front display. Unfortunately it seems impossible to get that information with one camera as the depth of focus/sharpness and the angle needed to capture both is just too big.
