    Like I keep saying. One has to be careful not to learn something every day. Thank you for the update of my ancient brain.

    FYI this is not a medical part per se. It is a labortory part designed to hold pcr tubes that take the testing swab and using pcr make millions of copies so there is
    enough material to test.

    Linuxcnc site is still quite alive. Both servos and steppers. SEM MT-xx servo motors are adequate for your mill. Having been there ... done that I would not bother to motorize the W axis. Belt...

    The only positive to that is that you get to define the strength of the floor. Mazak recommended 12" of concrete for my V5. Serious overkill
    What it got was ~5" of well cured concrete with as grid...

    I like the idea of 41L40 but of course HT runs up the price. :-(
    However, being of good cheer and possessing a fertile imagination ... this sounds like gun drill territory. Emulate a gun drill on...

    Another thought. Careful buying off ebay may get you a good 'nuf meter for a bit less. But maybe not enough less to make it worth the chance.
    YMMV

    I'm a fluke fan... I've owned 3.. one bench top and two handheld. If buying new then the fluke 114 should do nicely. I rather like my 85 but it may have features you don't need. Nulling the dac is...

    Tuning servos varies from easy to difficult. YMMV. Having said that let's start with some basics. I assume that the encoders are on the end of the servo motors and the servo motors are DC brushed...

    Ah! Orders of magnitude do count in places beyond paychecks. :-)
    I see you've been keeping up with theory. Early on I had just glass scales ( 5 um ) on my mill. Worked but hard to tune. Now I have...

    Hello Michigander ;-)
    Detergent and water are the recommended cleanser. A touch of peroxide probably wouldn't hurt. Easier on the hands then alcohol based stuff and available. Dawn is pretty good...

    Hi,
    I think the Arduino is underpowered. However, the Rpi4i is rather capable and the final cost difference of a working device will not be much different.

    From the wiki:

    I like the ideas various people have tossed out. Ni plating is really cute but requires a rather good analytical balance to execute.
