It looks like you might be using a Spot instruction for your tip dress. Which pressure schedule is being called for ? SPOT [ ,P=?, , ]
The pressure schedule can be viewed in the Data window. They always specify a pushing depth within their detail. Possibly your pushing depth is too small. I would compare the pushing depth to that of similar robots that are not faulting during tip dress.
And, yes, it also looks like you may have some payload setting issues.
