I've got a Solidoodle [Sanguino - ATmega644P] and I've recently installed a new E3D hotend. I need to update the max temp but I can't for life of me, this entire day I've worked on it, actually upload firmware. I always end up with "avrdude: stk500_getsync(): not in sync: resp=0xd7"
I've installed every single driver I could ever find.
I've hit the reset button before, during, and after.
I've unplugged all plugs [except stepper drivers, but I didn't have that problem when uploading to my Megatronics with step drivers installed]
I've tried many, many different hardware patch iterations for Arduino IDE
I've tried a few different Arduino IDE's [0022, 0023, latest 1.05-r2]
I've tried several different firmwares, many Marlin's, original, Lawsy's, Lawsy's later, plain Marlin, and I've tried Repetier
I've also tried countless combinations of everything above.
I'm at a complete loss.
Unless it doesn't compile right [a pin not defined, usually] I always get the error "avrdude: stk500_getsync(): not in sync: resp=0xd7" with the last two different here and there.
Every site I look at that has fixes for these errors has not worked for me. Hopefully I was thorough enough that you won't throw answers I've already tried at me, including turning it off and turning it on.
