Corrupted the firmware on both boards? That'd be really weird indeed.

I wonder if it was a USB port issue, and when you went to flash you re-initialized the USB port?

I had both boards flashed with adrian's Beta version,  the spare I have been using trying to get Viki LCD to work correctly so I might have screwed the firmware up on that one somehow wink

Once I flashed back to the latest lawsy build the old board started working again.  Just confused how the bed turned off mid print then could not get back on again.  might have been USB issue with laptop.  Will have to keep an eye on it to see if it happens again.

Could something have corrupted the firmware?

Check the input voltage from the power supply also and make sure you are getting 12VDC from that.

When I check the resistance of the bed I get 1.8 ohm which John from Solidoodle said is perfectly within range.

If I check the voltage on the bed pins when I turn the bed on I only get about 1.2VDC.  Is this correct?

Any Ideas why the bed will not heat anymore?
