    Mine only uses about an inch out of the reservoir for every 300 hours of spindle time.

    Pull the tools out of the pot before pressing reset. It sounds like something is interupting the tool pot...

    Well, they do offer drivers too, god forbid. Sometimes they will even replace your drivers with theirs, it has happened to me on my video card.

    I just have it turn my "high accuracy" mode on when I use cutter wear comp, ie G41, and turn it off with a G40. Rough without it and just turn it on when accuracy matters, like finish passes. Real...

    80D is extremely hard for a plastic, I don't think I have ever machined any plastics that hard. Acetals and nylons are in the 65-70D range if memory serves, polyethylenes are softer. 70 to 80D is a...

    I would pull the spindle out and send it in, unless 1500$ isn't worth 2-3 days of your time, but you will know it is done right, which it doesn't sound like it was. I need to update my spindle...

    Big Daishowa states 20 micron, so .0008", but I would expect it to be different for a 30 vs 50 taper and they don't specify. The gap is pretty big. I am wondering if a previous rebuilder ground too...
