Good morning,
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.
Are there any solutions?
Thank You
