My Melzi had one of the drivers go bad for the extruder, so I bought a new one on E-Bay. When I installed it and tried to home the axis's the motors would move a little bit and stop, one axis even went in the wrong direction( Yes the stepper was wired the same as before). I've searched and searched the net and found an article that says its a bootloader issue (fuses set wrong), buts its applies to GeeTech boards which mine isn't ( [
www.geeetech.com]), and the programmers being used are ones I don't have all I have is an UNO.
I'm just not sure what to do at this point, flash bootloader or firmware?
If I flash firmware the settings are confusing the config file has all kinds of things in it that need to be selected, or uncommented, like is it a Melzi or a Sanguino. From what I saw on the net they are one and the same. Melzi is based on Sanguino.
I hope someone can at least point me in a direction, Im totally lost!
Thanks,
Dave
