Marlin 1.1.0 RC8 resets on second layer, and stopping print

[tbowmo]

Trying Marlin 1.1.0 rc8 out on a GT2560 board, I have printed a calibration cube without problems, but trying to print a fan shroud (http://www.thingiverse.com/thing:1496109) the printer resets about 1/3 into the second layer, causing the print to abort.

I'm using repetier-server, running on raspberry-pi, printing via USB. Going back to marlin 1.0.2, and I can print without problems.

Reverting to older firmware doesn't find any issues. That only removes some possible protections that are in place on the later ones.

I am printing your file now. I changed the temps to PLA range because I don't have any ABS atm.
Where exactly does it stop? Mine is printing it just fine and I'm running RC8-RCBugFix with other (non-related) PR's included.

If you have an LCD, you should see the error that stopped it. You should also see the reason it stopped in a repetier log.

I believe you had a MINTEMP error.
My printer is now on Layer 5 and still going...

Layer 27 now... still going.

I am going to stop the print. I don't need this duct.

OK, I'll try rc8 again, and monitor the printer more closely.. (was working on another project while it was printing..).

Keep us posted. It would be good to narrow down causes for spurious MINTEMP errors and give a more meaningful error message.

I think I'm seeing the same problem.
I'm on 1.1.0-RCBugFix and the firmware crashes/resets on the 2nd layer.
