    I'd love to learn Linux, but that's not a project for right now, I'm too busy making parts. Closest thing I could go for at the moment would be NAS.

    NDA's come before the first little job. The need for a server comes much later. I have one main computer and a backup, no server. I don't foresee a need for a server until I have several machines...

    In my experience it costs more to deal with a regrind than a new cutter. Track the time and money spent to pack and ship the dull cutters, file the paperwork, store them separate from the new ones,...

    Well, as it's said, the easiest way to make a small fortune in machining is to start with a large one. But you do seem to have a niche available to you; to provide reasonable work at a reasonable...

    Your limiting factors will be the flexural strength of the cutter vs cutting forces, and the size of the gullet for holding chips (which will shrink when the cutter is sharpened.) If the cutter...

    If it's certain parts of the rail, then the problem is with the rail. It could have nonuniform thickness, corrosion, buildup, etc. I'd go over it with a fine stone.

    My first instinct would be that there's some particulate matter in the bearings. Could take them out and see if they spin freely by hand. If one feels rough, replace it.

    40K is still comfortable (barely) without ears on. 50K is annoying, and I'd wear ears if staying in the shop while it runs, but not damaging.

    Looks like the jet isn't turning off immediately when commanded to. You may need to add a dwell after shutoff.

    I get most of my tooling through Productivity Inc. in Plymouth, MN. In part because they're 20 minutes away and I can get most things same day. They do have decent stuff at decent prices though.
  22. Nexgen control, switching between inch and metric?

    On a nexgen control mill, if I want to run in metric mode, will I need to change a bunch of settings for the probe, recalibrate, re-touch-off tools, etc?

    Thanks
