Robotiq Gripper Exception with UR Polyscope 3.6

Hello All, I just have upgraded the polyscope GUI to 3.6 and the Robotiq gripper node starts to give problems. The report's summary.log says == Incident Report == Incident Time: Fri Jun 22 16:49:02 CEST 2018 Reporting Time: Fri Jun 22 16:49:03 CEST 2018 Stack Trace: java.lang.IllegalStateException: Modifications to program tree and/or data model must be inside a 'UndoableChange' scope. Use 'UndoRedoManager' to group undoable changes.at com.ur.injection.ThrowIfNonCompoundChangeInterceptor.shouldProcess(ThrowIfNonCompoundChangeInterceptor.java:44) at com.ur.injection.ChainingInterceptor.invoke(ChainingInterceptor.java:15) at com.ur.injection.ChainingInterceptor.invoke(ChainingInterceptor.java:19) (...)at com.ur.urcap.manager.ProgramDataModelAdapter.set(ProgramDataModelAdapter.java:58) at com.robotiq.urcap.gripper.impl.GripperProgramNodeContribution.exportGripperParametersInIntegerToModel(GripperProgramNodeContribution.java:174) at com.robotiq.urcap.gripper.impl.GripperProgramNodeContribution.exportGripperParametersToModel(GripperProgramNodeContribution.java:166) at com.robotiq.urcap.gripper.impl.GripperProgramNodeContribution.access$000(GripperProgramNodeContribution.java:39)(...)at com.robotiq.urcap.gripper.impl.GripperEditActionFrame$14.actionPerformed(GripperEditActionFrame.java:824) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2012) (...) I have uninstaller and reinstalled the URCap and the problem persist. I have also rebooted the robot. The summary.log is attached to this message. It seems to be, at first glance, that the problem is how the implementation of the URCap works with SW3.6. I would like to ask if somebody has has this problem and if anyone knows how to solve it. Regards, Rafael Rojas

how to prevent a delay in the full force application on a 2f-85 gripper

Hello everyone, I searched a bit on the forum but could not find any mention of my problem. My gripper is used in a machine tending application, it loads and unload a CNC lathe. It has been working for a couple of months but I had the problem since the beginning. When I go and pick a piece from my table, the gripper closes and the robot lift off the table and goes to the next steps. The problem comes when the gripper closes on the piece. sometimes it acts like the gripper does not apply full power immidiately so the piece is loose in the fingers, but after a moment it applies its full force and the piece is ''firmly'' in the fingers. This often lead to a piece falling off or turning slightly in the grippers, particularly when the piece is heavy or long. Today we loaded a piece that we already processed in the past months without trouble, but it kept dropping piece after piece while the program did not change. Is there a way to have the gripper apply full force immediately? I use the script function rq_move_and_wait() which I thought would correct the problem, but should I had a wait time after this function?

Re: How to determine if my sensor is functional

Hi! I followed your steps but when running data logger it keeps saying "disconnected". The device manager does see the sensor though. Thanks!
