    Default What motor, screw and gearing should I choose?

    The short answer:

    For a smaller wood and plastic cutting machine (and maybe – maybe! – some light aluminum), several people on CNCzone seems to have had success with 100-200 oz-in (0.7-1.4 Nm) stepper motors direct driving a 5 turns/inch (5 mm lead) ACME (trapezoidal) screw.


    The long answer:

    ... hopefully you can find in the attached file. Please, if you spot any errors or have trouble viewing the file (like missing characters or fonts), write a comment in this thread: http://cnczone.com/forums/showthread.php?t=5639, or use the email address in the file to notify me.

    Very good reading material Arvid,

    I'm going to have to look up the data sheet information for my steppers now.

    Maybe one of you have already done so and could post the specs. The steppers are from a few old HP Laserjet III's

    LABELED: Astrosyn
    TYPE: 23LM-C701-01
    P/N: RH7-1048 04
    5.2 V/Phase
    1.4 A/Phase
    1.8 Degree/Step

    First, thank you for this document. Second, this may be a newbie thing to do, but there may be a typo in your PDF.

    For the power equation you specify that it's force times speed (or velocity) but you write it at Force times distance F * s instead of F * v

    Third, I am creating a spreadsheet of the equations as a tool, and ifthere is any interest I can make a web form. We'll see.

    Default Web-accessible info

    Jay,
    It would be great to have that kind of information available if it's not already on this site.

    I have this Stepper motor and have tryed it using my Sherline mini Mill.
    The following plastics were tryed:
    Delrin Great at slow feed rate
    Acrylic nice finish but needs lubrification(I use 10W30 motor oil)
    Lexan Great at slow feed rate might be ok to mill at higher feeds if lubricant is used.

    This motor does not have the force to feed a larger end mill(Grizzly 1005).

    I have retrofit over 300 milling machines, and the only thing i can say to you is, there is not that much cost differance between a 200 oz in stepper and larger ones. Go with as large of one as fits your machine and budject. dont risk going to small.

    no, there is no correction to this board. It is apparetly flawed and not useable in the first place. The actual linistepper board, with it's open source layout, source code, and design DOES work. Please do not be confused by the problems afferriers had with this board. The actual linistepper board has NO problems; it works just fine.
