I am using a UR10 arm for a printing simulation and have attached an extruder to the tool. I apply a G-code via a USB drive for the URCap toolpath. Due to some cables and connections of the extruder, I need to limit joint 3 from rotating and keep it fixed. I used the safety joint limits, but this causes the G-code execution to stop immediately. I was wondering if anyone can help me find a method to solve this problem.
