Hello I Bought two Control boards, I have been trying to upload the firmware in both of them , I haven’t forget the programmer jumper just in case, I have checked as well the configuration in the Arduino IDE, ports and board. However I always get the same error in both boards:
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
I bought a few days ago 'the vertex k8400, yesterday I finished the complete assembly of the printer, I followed all the steps in the manual, when I get to install the firmware for one hot end with Arduino 1.0.6 on Mac Book Pro MAC OX 10.6 Yosemite, I get this message in arduino: avrdude stk500v2_receivemessage () timeout … I followed the step by step procedure JPROG installed on the two pins.
I have put the jumper in the board. I had uninstalled and installed again the drivers. still no way to program the board. actually I borrow a ramps for checking if the drivers are working. I uploaded the firmware without any problem.
