Hello every one
i have a prusa mendel built (using ramps1.3) and have been calibrating and testing motors and heated things for the last few days but for some reason i'm now unable to upload anything to the mega using the arduino program. I'm using arduino 022 as i've been unable to to get arduino 1.0 to recognise the serial port (is greyed out, i've seen a few people with this problem but none of the solutions i've seen have worked for me), anyway 022 has worked in the past but now has issues.
when i press the upload button arduino says "uploading to I/O board" and shows the size of the file, however this goes on indefinitely. if i pull out the plug it says "Done uploading" but the error log says "avrdude: stk500_2_receiveMessage(): timeout"
Has anyone else seen this before? I've done a bit of googling but so far havn't found anything helpful
i have definitely selected the right board and serial port. The firware i'm using is sprinter and has uploaded in the past with out issue
