Loosening the screws fixed it.
Yes I think we are saying the same thing. The last three braces were out of tension, compared to the rest. The braces themselves do have a minimum rail position and I thought I designed then in such a way that clamping would not push the tubes out, I thought the clamps would just open up…I was wrong. Actually just found this out here, Something isn't perpendicular
I set me tram near the 0,0 position so that was my reference. I will take some measurements today, and I have a old Beta beam sitting here so I am going to mess with the tensions to see what happens.
Both of my YZ plates are firmly grounded so twist on my build isn’t the typical twist some get when a plate sits crooked and the front of one side can be tapped on the table.
There are a few ways to adjust most aspects of the machine so I try to start with the most direct checks and adjustments first. A good example of this is adjusting the tram with the bottom tool mount. It has the most direct effect of the tool angle. You have an even finer adjustment using the top tool mount, I just never usually tell people to do that.
