    Calibration routine from ar2.py non-responsive

    in Questions

    I have finally finished my AR2 build. I loaded the arduino sketch 2.0 and confirmed all limit switches operatonal. I could not run the exe to calibrate successfully on windows, I got a serial error for permissions on the com port that I could not resolve. I then tried to run the ar2.py on linux and got it to run. It takes my updated com port in the code (/dev/ttyUSB0) and then when I click the calibration button nothing happens.


    Is there a linux-approved fork of ar2.py that someone has worked out the kinks? I can't get any feedback from the ar2.py program; I assume it's trying to move the motors but isn't moving because something is wrong but I'm not sure what. Any ideas? Anyone run into this before? thanks!

    Apparently I misinterpreted the labels on the mega shield; all jumpers d2-d13 were shifted up one hole. I still can't get J4 to respond but all others are; I'm assuming it's a separate issue w/ J4.

    J4 wiring, motor and driver were fine...apparently I lost the set screws for this particular pully and thought I would remember they were missing but did not when I picked back up on it a year later.....shaft was spinning quietly in place. Robot is good now.
