I am working with milling application with this robot.
This is not position accurate robot. I checked for .pid file inside controller but wasn't able to find.
having issues with cartesian values which robot is giving.
A1 axis for 0,+90,-90 position gives different values for X,Y,Z.
it gives variations while machining using track.
but my concern is this changing of values.
for Y axis when robot is in home position its value is changing over a period of time (2 weeks approx).
it got changed from -2.78 to +2.78 to now -0.98.
why these values are changing and how to resolve.
there are no errors showing from controller side.
checked reputability of the track its good but when robot machining is going on (ruffing) its carriage is moving approx 2 to 3 mm.
it shouldn't be moving when robot is stationary right?
one more thing I noticed was counterbalance sound.
I have recorded one video also for that.
please go through the data I am attaching and please advise.
