::heading=Problem
There is some loose originally on the Hand-E, it's the normal behavior.
But sometimes, customers who use custom fingertips will notice that they are anormal loose.
::heading=Troubleshooting
This can happen when the fingertips are longer. By that, I mean that since the custom fingertips are longer, small movements will appear larger since the TCP will be further away from the gripper.
There is another reason why this may be happening. Fluids such as cutting oil may have entered the top casing and may have "pushed out" or "mixed" the Mobilith SHC1500 grease that is applied when the gripper is first assembled.
The Mobilith SHC1500 grease allows proper movement of the rack and pinion but also provides restriction and adherence for better gripping force.
::heading=Solution
The solution would be to follow the "Rack and Pinion Mechanism Cleaning", Section 6.3 of the Hand-e Instruction Manual. Link here: Robotiq Hand-e Instruction Manual
It will instruct the customer on how to disassemble, clean, regrease, and reassemble the Hand-e gripper. The issue should then resolve itself. Needless to say, make sure the customer has also tightened the screws holding the custom fingertips to the gripper racks.
