Repost from general:
I have a used Mendel90+Panelolu2 and I am trying to upload a new config h ( to adjust my Z zero height) to the Melzi board.
I am using Arduino 1-0-1, which verify`s and transmits my update. Reporting it as successful.
I then use pronterface to load M502 followed by M500.
Then home all axis and the zero has not changed.
Being a newbie I am completely flumoxed.
Please if you can think of anything that may be amiss, it would retrieve my sanity!
Thanks in advance
p.s Arduino reports after successfully loading file:- avrdude: stk500_getsync(): not in sync: resp=0x00
