@Geswearf As someone who has been researching which mill to get and comparing a bunch of the PM machines, let me share what I found. Most of the qualitative marketing speak is around the quality of the machine and, by that, I mean generally the tolerances the tool is made to.Don't think about it in terms of the 728 being more or less accurate than another machine it's more about the ease of achieving and maintaining a given level of accuracy. Things like scraped ways just mean that extra care was taken to ensure those components fit the way they should which, in turn, means you as the operator should need to spend less time fiddling with them and more time making parts.
