Ok this is not intended to start a war, coming from a mechanical engineering background EVERTHING man made has tolerances and repeatability . I am asking here because I know a few people have dug into the machine pretty deep, so why replicate their work
Just wondering for example if you probe touch Z height 10 times without changing the bit how consistent are the numbers.
There’s a post somewhere about this subject, someone did some testing
@cyberreefguru did it and it’s on his YouTube channel.
Cyberreefguru has done some very good work, but his tests seem to focus on repeatability of X, Y travel. The test was from home X (or Y) to a given distance and measuring the error from a “golden spot”. He did not evaluate the Z assuming similar results, and I do not disagree.
However what I am asking about is when the Z probe is introduced into the process. Basically this is a stacking error case. Take this as the extreme if the error in Z probing is +/- 0.1" then all the complaints of Z being offset between bit changes (ridges on the bottom surface)
would be explained by Z probing error.
