Just wanted to report that I've been using v0.91 rev6 for a while now and it seems to be fully stable now!
Great work, whatever the magic was that fixed it

@Darki: note there's also a similar discussion on GitHub on this:

Interesting, it just failed on the 10h print, just a few minutes before I saw 96% on the display. (27.4mb file)
My first fail yesterday was on a 5h print somewhere around 95%. (14.9mb file)
So it doesn't seem to be related to filesize or print duration, peculiar that both are at about the same percentage mark though.
This was using the USB charger, I'll try a quick print next and log on the PC

Sounds like a good idea indeed!
Just checked motion.cpp and those 4 lines are already uncommented btw.

Thanks, will give that a try just in case it stops again.
I'm suspecting it may have more to do with the ribbon cables and not so much the power.
I'll try and see if I can setup a worst case scenario, crossing them, having them close to one of the motors, see if I can swap them with longer ones.
So far a 10 hour print is at 85% without issues so it seems it's not a reproducable on my machine as

Would it be an option to print the amount of SD red&write messages to a debug line (or page) on the LCD?
Just count them and display a number, and maybe the last error message for example.
Or detect when the buffers are 0 and print hasn't finished yet and print the last error for example.

Wow you're quick, great work on the delta mechanics btw, very very smooth results!

Thanks for the tip, will give that a try.
I had it connected to a USB hub connected to the computer when it stopped.

Had a very similar problem here, 94% into a 5 hour print.
Also on a custom built Delta with RAMPS 1.4, using a Reprap discount LCD (non graphical), also started from SD card and not connected to PC, using firmware v0.91 rev5
I noticed "Buffers" on the LCD displayed 0, not sure if that indicates something.
Will post if I can get a log of this on the host computer on another print.

Found the changelog here
Commenting the line that generates the error seems to make it compile, will have to wait for a current print to finish before I can try though.

Hi,
Great to hear about v0.91 rev5.
Btw is there a changelog somewhere?
It seems the "Download complete firmware incl. these settings" button downloads the firmware with default Configuration.h file and not with custom settings.
"Download Configuration.h" does seem to generate a config with custom settings, however when trying to compile I get the following error (yes indeed I don't have a h

Thanks for the input, your Cherry Pi looks like a really nice build!
I was indeed thinking about option 3 and have also found a similar discussion regarding Graber wheels vs MGN12 rails on the google group here:
Seems like both perform very similar, noise on the rails may be slightly more but most of the noise reduction can be gained by isolating the machine from the table and motors from the

Hi,
Finally I've decided I want to tackle building a printer from scratch and have settled on the Mini Kossel design.
There seem to be two approaches for the linear motion, steel rails or wheels/rollers and I'm trying to decide what to go for.
Does anyone have insights into the advantages/disadvantages of each approach?
Price is something I can look up, but how about accuracy, durability, maint
