["Heating failed" screen flickering]

Which of the two problems do you have?  "heating failed"?  which is very common and well understood?  Or "flickering display" which I have no idea what causes that and I've never seen that before.  If it is "heating failed" then did it happen when you first heated up the nozzle or during your print (for example when the fans come on a few layers into the print).

 

I have the same problem. They come together. If I the screen dimming and flickering, there's a good chance heating will fail. Sometimes my printer will work fine for days at a time, and then it will give this error for days.

I just put together a Ultimaker Original I bought at MakerFaire SF Bay Area two or three years ago.  I'm getting this problem.  I bought a new arduino, swapped it out, after tracing the connections and verifying continuity and switch operation, and had the same effect.  If this is a known issue, could we get some resolution?  What do I do next?  I worked around it for now, and I'm able to make prints, but I have fear of damaging the machine if something goes wrong.

Okay tried it out....despite the settings being Ultimaker Original and No Heated Bed, if you go to use this, the Ultimaker Original sits at "Heating bed".

Umm, you guys test this stuff, right?  

 

We did test, quite a bit. But... well, all our originals where upgraded to + or heated bed upgrade status. So that was missed.

There is a workaround, you can enable the heated bed setting and set that to 0, that will work around this problem till we have a fix out.

 

Well, some time has passed. Is it safe for a newbie with an ultimaker original to try it yet?
