Uploaded Firmware to latest and lost my display
I have HE3D Delta 180 (Kossel Clone) with an Adruino Megga, Ramps 1.4 and looks like a 2004 LCD (this is the one I have http://www.bigtree-tech.com/index.php/en/production/detail/101) . My system was working before I updated the firmware (I had no voltage on D9). I used the config.h in the version of the firmware provided by the manufacturer. It uploaded successfully and now the printer doesn't respond and the display is blank. I tried to revert back using the firmware provided on the SD card from the manufacturer. Still no joy.
I can program the adruino, If I use a blank entries in the wizard, I can get ponterface to see temps and move steppers.
What the heck did I do ?
Did I nuke the card ?
