Hi folks, as a result of a slightly unexpected error in the dimensions of a piece I profiled I realised that I could not ignore the backlash on the slides of my little Novamill. Measurement showed it to be 0.03 mm on X and Y, 0.02 mm on Z. I have turned on compensation and set these parameters and it seems to work fine, but I was wondering what level of backlash was to be expected? I have posted this question on the Denford forum and Angeltech has suggested I adjust the thrust bearings, which is good advice that I'll follow, as well as looking at the gibs, but would be nice to know what I could expect? The machine though oldish has spent most of its life gathering dust in a school, having clearly not had anyone who had a clue in charge judging by the cutter jammed in a collet when I bought it off ebay! So I don't think there will be significant wear.
John.
