In the below two images, you can see the ETC Source 4 19deg fixtures aligning themselves incorrectly along the light pipe. I took the same fixtures in the file above and did 'Replace Instruments' with the 19deg instrument. They also will turn and focus as they should when assigned a focus point. In this first image, you can see that the ETC Source 4 26deg fixtures hang great just as they are supposed to. The problem is illustrated by the below images. I have tried replacing the lights with their 26deg sister and the 26degs hang great as they are supposed to! I only have the problem with ETC Source 4 19deg. I do not have the same problem with my 17deg fixtures or my Robe movers. My problem only happens when I try to hang ETC Source 4 19deg fixtures from the pipe. I have been struggling with hanging ETC fixtures on a light pipe for awhile now.
