hi there, any one else suffering x axis twist on their 2x 2060 profile 1500mm axis? I'm getting different depths of cut in one direction than in the other direction on x due to twist In the x axis. Really frustrating, I've made corner brackets to support x on y gantries to shorten the span. Still same amount of twist. I've bolted them together. But you can still literally twist axis with a small push on the z axis. Completely out of ideas now. Somehow I don't think this design is up to being this size. Thickest material I've managed to cut accurately with it is 3mm ply in 2d. Even adding 2mm heigh tabs makes x twist and z kick out. Adding 6mm thick ali triangular corner brackets to the internal corners below the x onto y gantries, are solid. The twist only seems to happen in the span between the brackets. Which tells me it's simply not up to it. Any ideas??
