I've been trying today with the manual method, going through the notebook went well and things were converging up to a point where I started to oscillate. This would be fine, but the errors were still very high, so, probably what you said about the hand measurements is happening here. But it was nice to go through the notebook and see your approach on the optimization problem.
I have done some measurements on the machine, and sure enough there are some significant diferences in the distances between the towers, so definitely that is at least one of the problems.
I will build a z probe for the machine and retry the notebook and maybe Richie's firmware, it also looks very interesting. And as much as I would like to try out an implementation for it, after more detailed look at the problem, I'm starting to appreciate that it is more complex than it looks at first sight. Though it is a very interesting problem!
Any recommendations about the z-probe?
