5mm off on the Y plane!-PoppaJim-06-20-2023 Hi - hoping for some guidance on setting up an ABB IRB120 for Milling. Did my first test by milling a simple 100mm circle in some foam. The curve was generated in Fusion. Everything works well except there seems to be a calibration issue: The circle is 5mm different on the X Y plane. I thought maybe I should recalibrate the Robot and did that no change. So I am assuming that the issue is in calibrating Robodk to the real world - the base frame. Can find any references for doing that. Can someone point me in the right direction, please? RE: 5mm off on the Y plane!-Albert-06-20-2023 We need more information to better help you:

I Calibrated by re-zeroing all axis and updating the rev counters with the markers in the correct position as you describe. RE: 5mm off on the Y plane!-Albert-06-22-2023 How did you calibrate your tool? Can you share the RDK project?

I recalibrated the joints and reset the rev counters but I gather I need to calibrate to the base planes as well? The distortion seems to come from the Z plane not being verticle. Whats the best way to fix that?Calibrate reference ? RE: 5mm off on the Y plane!-Albert-06-26-2023 Once you update your revolution counters you should teach your coordinate systems again. If you defined your coordinate system using 3 points with the robot, the plane will not be accurate and it would explain the errors you see. |
