I have an UM2 that I upgraded to an UM2+. I have been printing for the past couple of months fixing various issues along the way, but this one has me stumped.
Problem: The Ultimaker 2+ will reboot (the screen flashes the ultimaker logo) very early in the print, usually before the 10th layer, and sometimes as early as printing the brim. This started happening around when the latest Cura version was released, but I don't know if that is actually the issue (I see this happen when printing files that were sliced on older versions of Cura)
As I am completely unsure on what causes this, I'll post my process of printing.
Slice the model in Cura (usually get the model from thingiverse)
Export to an SD card and plug into a running UM2+. Wait for a few seconds for UM2+ to read it.
Start the print
While the heated bed is preparing, I have noticed that the nozzle doesn't heat up to the temperature 220 C. So I usually TUNE->Heat nozzle-> 220 C
The print starts and I am watching it to make sure that it extrudes. It seems to extrude a bit, but most times I have to apply some pressure on the filament going up into the feeder to get the teeth to find purchase. I think this may be due to the previous print failing and grinding.
Usually within the first couple of layers I'll see the entire machine shutdown and reboot. It shows the first screen that you see when you boot up normally. The print head is still on the print and the bed is raised.
This is the 2nd time that this has started happening. I fixed it last time (for a couple of prints) by factory defaulting the box, cleaning the glass plate, and setting it up again. I set it up by adding a custom filament type on the box to set the temperatures to 220 for all nozzle sizes and change the diameter to 1.75mm (is this bad? does Cura specify those settings in the gcode?). I plan on pulling out the printer and checking the temperature sensor wires next, but other than just re-plugging them, I'm kind of lost.
My main question is this: Is there a good way to get the logs of the system to see what happened to cause it to shut off? I'd love to see "HEAT ERROR" or "FEEDER ERROR" or really anything to point me in the right direction.
Other questions include: Is there a way to check the firmware of the UM2+? I have no idea where to check it at.
Sorry for the story, Thanks in advance for any help you can provide. I'll try to catch a video of it happening, but it happens fast.
