I’m not sure where this urban myth comes from, but it keeps cropping up here on the forum. If the layer position is off by half a step, then every layer will be off by the same amount. The error does not accumulate. The z axis has 2560 steps per mm, so any layer thickness error is very small indeed.
An error of 0.001% in every layer means an error of 0.001% in overall height, not an error multiplied by the number of layers.
People seem to ignore the fact that the x and y axes are only 62.25 steps per mm. Yet nobody ever says the we should only print things that are an even number of steps in x and y.
