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?

As far as epoxying them together the bottom piece should be symmetrical. Just make sure that on step #3 on page 41 that the 2 holes are as shown when inserting the J2 spindle - so that when assembled the limit switch can be mounted as shown in step #4 of page 46

Good morning. I am 3D printing the robot. I have downloaded the AR4 .stl files. The J2 file is just one piece and does not fit on my printer (300x300x300) Where did you get the J2 files that is split? Can you share it with me? please.

Thanks in advance.
