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!
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.
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.
