    Hiwin HG-20-E2-KIT

    My CNC has Hiwin HG25 linear bearings. My current maintenance has been to use a manual grease gun to questionably lubricate them. I say questionably due to being a one person operation I can't really...

    Re: Possible CNC rebuild using Avid Components

    That was my thought. Was wondering if any other machine ever did that. (Foam is too messy for me to consider.)

    Possible CNC rebuild using Avid Components

    Couple months ago I came across a 4' x 4' 2006 Practical CNC at an auction and it followed me home. Minimal Google shows that company was not well regarded. The CNC was bought to cut prototype foam...

    Thanks Gerry!
    I was at HIWIN looking for this and could not find that document. It ends up that 25.4mm is ideal distance, appreciate HIWIN taking care of imperial customers. Now just to use a 1-2-3...
  5. How to determine HIWIN HGH20 blocks clearance to rails

    This is in DIY since the company that built it (Practical CNC) went bankrupt quite a while ago and I never saw it under power. The machine was purchased in 2007 by a university engineering lab to cut...

    [QUOTE=hfjbuis;2464950]
    That is not normal. You are right, it didn't need that today. I think my issue yesterday was going into Arduino and running a sketch which stayed active on the UNO

  8. How does UGS know Arduino pins for stepper drivers?

    What I have is an Arduino Uno connected to a breadboard with three A4988 stepper drivers and one Nema 17 stepper. There is a 24v 2a source for the stepper.
    This is a trial configuration before...

    Sanyo Denki contact or part number help

    My CNC has a Nema 34 stepper for the Z axis from Sanyo Denki. The part number on the stepper is SH2861-5142.
    In the catalog there is a SH2861-5141, but the mH inductance is 3.7 which would be a...

    Re: Ranking of BobCAD-CAM

    I've had bobcad since version 17, currently at 31 and had to read all the bad comments for a long time. Interesting to read the positives. Actually my best use of bobcad is creating wire frames for...

    Re: Controllers for 3D cutting

    Jim,

    I think there is not a lot that can be done to correct the limitations of the various softwares involved, at least not at a price point that most of us can handle. [That is the crux of my...

    Jim,
    I am amazed with Fusion CAM sometimes, I was milling a series of exactly the same circle pockets in a piece and it jumped around rather than going to the one just next to it.

    Re: Controllers for 3D cutting

    Jim,
    WinCNC is used on several brands of $40-$60,000+ commercial OEM CNC in the cabinet manufacturing and sign arena. Sold to individuals at $1,250 so not really entry level hobbyist.

  21. Re: Profile Rail Wood Frame Router, 25" x 37" x 6" working area

    I think the $250 is reasonable and acceptable for the home hobbyist. My thought is there are a couple different types of customers; those who intend to build an entire machine verbatim, those that...

    Re: VFD spindle as drive motor

    You should check out the weight of a 2.2 kw spindle, which I believe is 12 lbs. I recall people needing to put springs on the base Sherline models to help the Z axis stepper rise.

    Re: Mach3 XML question

    I can't comment on G43 use, is it superfluous or a reasonable way to set up for a safe gap from Z zero?

    I use Vectric for CAM on basic 2D paths. If a solid, or 3D then I use Fusion for CAM.

    Re: Mach3 XML question

    I move the tool with the jog function to the Z position I want and then choose "Z zero" from the panel. Never a problem with X or Y, which I set in the same way.
