    Having now seen Thor in real life I can tell you the pictures do not do it justice and then she moves and when she moves the earth moves with her lol.

    A true work of art

    Thanks for taking the time to take and share the macro shots, its nice to see exactly what the finish is like from different machines.
    No problem, Ill do more of it as I do more machining and work out the good / bad / ugly of the machine's ability.

    The macro shot makes the part look fairly horrible however in reality, its not. Its 'as it comes' and can easily be polished up.

    Does anyone know what NT30 spindle this guy might be referring to?

    That guy has his shit together ;)

    This bit I found interesting and I never considered but makes a lot of sense makes no difference to your machine though lol.

    "When you go with Chinese ballscrews, I think it is better to go with 5mm pitch, at least in my case as I dont need very fast rapids, due to force of the ball on screw. 10mm pitch screws will produce twice as much force on the wall of screw, and I wouldnt be surprised to see backlash even faster on 10mm pitch screws."

    Maybe in a production environment at 200mph, if your daft enough to expect the world from a cheap screw, you deserve the results from doing so. (not saying you are)

    Does anyone know how to deal with dual probes, on NC and one NO, going into the same probe input?

    Can I run two probe inputs?

    This is the issue, how else to wire this (goes into CS Labs) input 3.

    you could use a relay on one output to get both of them to NO or NC

    I've been thinking about exactly this problem for my own machine (also using CSMIO). I haven't built the touch probe yet but I was intending to use a simple bit of circuitry to invert one of the signals and then combine them. I'm not sure that you can solve the problem without adding something outside the CSMIO as it only has one input that is suitable for the job.

  14. You need to invert the NC signal to NO, otherwise the probes will interfere with each other if run in parallel.

    My preference is to run probes NC, as then any circuit failure triggers a stop, but then you'd either need a switch to swap between probes, or wire them in series.

    Either would be possible with a transistor or two, and a couple resistors.
