Does any one have a Sanguinalolu board with a 1284p chip and ceramic resonator working and printing?

If so could you please use avr dude to check your fuse settings for me?

I’ll check my sanguinololu later this evening if someone doesn’t beat me to it. I think it has a resonator instead of a crystal. What’s the command line flag for checking fuses with avrdude?

You can check the bottom of the board under the chip. If there are three solder pads close together in a straight line its probably a resonator rather than a crystal.

These are what I use for the Melzis shipped with Mendel90:

atmega1284.bootloader.low_fuses=0xF7
atmega1284.bootloader.high_fuses=0xD4
atmega1284.bootloader.extended_fuses=0xFC

Should be the same for Sanguinalolu I think.

I don’t have my programmer with me, and cannot seem to get avrdude to read using “stk500v2”; I’ll have to grab one of my arduinos and use that as an ISP. :confused:

No worries I just resolved the issues with my x axis not moving!

@Mike_Ashcraft , what was the issue?

There is a stepper enable pin setting to go high or low to enable it was set wrong for the x axis

If you will need it my settings on sanguinololu 1284p with ceramic resonator are:
Low = 0xE6
High = 0xDA
Extended = 0xFD
