Is it possible to upgrade the firmware of my UM2 using the SD card ?

Recommended Posts

Is it possible to upgrade the firmware of my UM2 using the SD card ?

The reason I ask is. I installed the new version of Cura last night.

Then it offered me to install the latest firmware to my UM2 :-)

Only problem is.. I have no latop anymore.. and my big computer is 10 meters away and downstairs from my UM2. If I need to install the firmware.. I have to go up to the printer and very carefully bring it down through a very tight spiral staircase.. then bring it back up...

The last time I had to do that. the weight of the UM2 swing me almost over the side of the spiral staircase and I had to grab the wall with one hand and quickly grab the ultimaker2 between my other arm and left leg before we were both dead.

so is it possible to put the new firmware on a SD card and click update ?

Ian :-)

If it's just 10m, you can use a long USB cable ;)

Preferrably take something with a built-in active repeater, usually more than 3m of cabling can lead to USB failure.

And DON'T use multiple short extension cables - that will almost surely not work.

You could try using a powered USB hub instead of a repeater, but that just makes it unnecessarily difficult :p

There's also some more complex solutions, like USB to LAN and back converters, but even these don't seem to be very expensive...

I have no idea if that would work without any problems, but theoretically it should.

Arrgh...you were quicker than me. I wanted to write something similar as this is a typical Ian-suggestion... :lol:

Don't worry, Ian, that's just our way to say we like your posts... ;)

Seriously, there are five meter active USB cables (it's acutally a cable and a hub in one) and USB specs say you can add them up to 25m. But they cost a small fortune, I think. So maybe it's even cheaper to buy a simple laptop.

It requires bootloader changes that I didn't get stable. And you cannot change the bootloader without an ISP programmer. So most likely, no. Sorry.

Code for my experimental bootloader is available at https://github.com/daid/UltiBoot

 

Can i replace my boot loader with this one if i use ramps ?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
