I have troubles with my gantry, I’m not able to make it even close to being square. I’ve understood that I should break the gantry in by using it first, but the lack of squaring is pretty severe. I’ve got a hunch that its caused by the pipes being too uneven, but I just now had another thought:
Could the tensioning be affected by the fact that the bolts are threaded all the way? Should they be smooth, so that the whole tension “region” is loosened or tightened evenly? If the threads dig into the plastic (which they often do), I wonder if it affects the properties of the tensioning??
