I have just recieved my sainsmart melzi board. i have yet to connect it to ANYTHING ie. stepper motors/hot end/heated bed
i have however
Switched the jumper to usb
attached the cable
i had also got usb drivers which recognize it as a com port now.
however my led flashes at a consistent rate is this normal?
also when following the steps mentioned in the mendel pdf it says to use arduino 1.0.5 included. i have done that i have all the files and have got to the part where i assume i upload firmware to it ( pardon if i am using the incorrect term) it included me opening marlin.ino
which i did. also to set the board type to melzi 1/atmega 1284p
now i get this error in orange when i click the upload button
avrdude: stk500_getsync(): not in sync: resp=0x00
What is going on here do the steppers etc need to be connected?
i have the correct comport setting and the light even momentarily goes off during this sequence almost like it gets a request and interupts the light im puzzled
I'm not familiar with the Melzi, but am wondering if there is a jumper on the board that prevents the firmware from being overwritten in a production device that you need to change so that you can flash it?????
