This thread collects reports about the arm feeling stiff in drag mode after upgrading to v3.9.9, and about the missing friction compensation setting.
Status
Known warning. The issue has been reported. Fairino Europe support said the setting should come back in the next software version.
Symptoms
- Moving the arm by hand takes clearly more force than before the update.
- The manual describes the setting under Base and Joint, but that menu is not there.
- New tables in the maintenance area changed nothing noticeable for users who tried them.
Known checks
- Confirm that tool load and center of mass are still correct after the update.
- If you teach many points by hand every day, test v3.9.9 on one robot before upgrading the others.
- Do not change maintenance tables on a production robot without a backup.
Please reply with
- Robot model
- Software version before and after the update
- Whether a tool is mounted, and its load settings
- Whether you found a working setting
