On my first powerup of the system I am testing the motors with the Jog from AR2. But J1 jog does nothing, J2 jog controls J1 motor, J3 jog controls J2 motor etc etc up to J6 jog controls J5 motor. Its as if they are all displaced by 1. All the motors I can control will go forwards and backwards as they should. I have checked all my wiring to the best of my ability. Any ideas?

Just a quick query about this, can anyone reply giving me the clearance between these 2 parts, as mine seems very close, I can easily print a part of J1 spindle to make it up. Thanks

Just been printing the 2 parts of the J2 arm. Before fixing them together..permanently.. I noticed that there was a hole on the side of each part. Now if I had fitted them together as printed, ie bottom to bottom, then the 2 holes would have been on opposite sides. Now this disagrees with the picture of a one piece J2 arm, where they are on the same side. One of the 2 part J2 arm is symmetrical as far as I can see (whereas the other has an extra hole on one side) so I assume I can reverse the 2 parts so that the 2 holes on the sides appear on the same side. I hope I am correct, but does there need to be a correction on the STL of the 2 parts?
