@53581
I tested my wires and they are good but I have not tried cleaning the board yet.
I have also test from different computer with no results. Thanks again.

Also If the board is bad is there anybody that would repair it?

@Phaedrux
So I clean the board and above the lights on the board it pretty bad but it clean up very well and I could even tell anything was amiss when I was done. So what do I do from here just buy a new board or is there a way I can pinpoint it more?

Is there something on the board that all I/O pins other than 5 and 6 have in common that could have fried?

Phaedrux

If you had an oscilloscope you could check if the servo pin is sending out a signal.

Can you show some close up photos of the board?

53581

I don't know what that chip is though.
Does my config look fine?

Phaedrux

Do you have a multimeter you can use to measure the resistance on R28?

53581

@Phaedrux Yes I get 9.9 kΏ.

all right I did figure out this problem finally. the deploy probe file was messed up, I'm not sure how it slowly got worse and worse but is now working! I do have one more question however, I am geting this error and I do not know what's wrong does anyone here have answer?
thank you for your help!

Phaedrux

You'd have to share with us the macro 2_tests_completed and config_default.g

The error message would make more sense in the context of those macros.

@53581 those are old board testing macros. You should not need to run them and can delete them.

Replace with a configuration from the config tool.

@T3P3Tony Ok, Thank you!
