    Re: Gray scale height map for pattern

    I don't see a graphic in this post ( :^( ) and wonder if they might time out.

    Your work is outstanding, and I would like to apprentice under your tutelage.
  2. What are Bearing Collet Nuts and how do they compare with standard ones?

    I read a recommendation that switching to a "bearing collet nut" would eliminate the worry of over- or under-tightening the standard nut.

    I've found some manufactuers, but no discussion of how it...

    Re: Tool Height Macro [here's one for LinuxCNC]

    "Baloney" Alert:


    NO, IT ISN'T.[1] Electrically, it's the same thing as a lump of metal with no moving parts. The spring and plunger are NOT in there to make-or-break an electrical connection,...
  4. Re: Chinese pancake-style make/break Z-height setter detector: how's it work? [Pictur

    SOLVED. Short answer: It is NOT a "switch"--of any kind. It is the electrical equivalent of a lump of metal, connected to electrical ground.

    While it does have "moving parts," they have everything...

    Re: Tool Height Macro [IMPORTANT EDIT]

    Incidentally, I just realized it would be wiser to set the variable #<ZMAXDOWN> to something LESS than the full-travel of the height-setter's plunger.

    For example, supposing the plunger's travel...
  6. Chinese pancake-style make/break Z-height setter detector: how's it work? [Picture]

    These were all the rage a few years ago when this one was shipped with my machine. Now they're not showing up as ubiquitously in searches.

    I've used mine less than a hundred times, but it has...

    Re: Tool Height Macro [here's one for LinuxCNC]

    I created this for LinuxCNC with my Chinese CNC, which came with a "Z height setter" and a cable connection for it. The tool is spring-loaded, normally closed (NC), "knife" switch with its two wires...

    Re: website not working

    Sorry for being 4 years late, but cnc4free.org is up today in 2017.

    I'm wondering how mature this is for doing human faces. Has anyone been using it to make carvings of walk-in clients?

  10. Re: Needed: source for replacement plastic lower dust collection bag 6-mil HF#97869

    Thank you, Gerry, for doing my homework for me. Again. I had actually searched amazon and ebay (and the rest of the web :^) ) extensively, and even run across these very Powermatic bags, but I...
  11. Needed: source for replacement plastic lower dust collection bag 6-mil HF#97869

    My Harbor Freight 2hp Dust Collector "manual" advises to "replace the lower dust collection bag if it becomes torn" but--of course--they/it are/is no help sourcing the bag to do so.

    Re: Dealings with Dropswell

    I imported a CNC machine from Red China and discovered the normal way to pay is a bank transfer: 1/2 down, 1/2 on shipping. As you would expect, it's hard to get info on the reality of the firm's...
  13. FWIW: Controller/brain transplant for 3-axis Chinese CNC router to use parallel port

    This is just an FYI for someone finding themselves in my situation: having a Windows-only machine with a gameport interface and wanting LinuxCNC and a parallel-port interface.

    The 3-1/2-axis[1]...

    Re: Need Motor Wiring Help

    I'm not a motor engineer, but I do know a thing or two about GIMP (the image processor), so rotated the image so I can read it. :^)

    I am also something of a simpleton, so it looks simple to me.

  15. Re: Where to Buy? "Made in India" carbide tooling

    Oh!

    I do not intend to give the impression that I have not been perfectly satisfied in all respects heretonow. Nor that Indians are superior to any other ethnicity in terms of superiority. I feel...

  17. Where to Buy? "Made in India" carbide tooling

    I recently had an idea that, maybe, I could help the world economy by spreading some USD around to other Asian countries. (Gee, for ma's sake, I hope India is in Asia...)

  18. Re: How to troubleshoot spindle signals (On/Off, PWM) on a pinouts?

    Okay. Back. Two PCI parallel port cards arrived this morning, so I worked until 11 pm getting one to talk voltages to a breakout board, and I'm back to where I was before Groundhog Day.

  19. Re: How to troubleshoot spindle signals (On/Off, PWM) on a pinouts?

    "There! I fixed it!!"

    Lucky for her--but sad for me as you shall see--I spied a box of surplus wall plugs first. I found a 12Vdc/500mA which measured 20Vdc. I was unable to find out what current...
  20. Re: How to troubleshoot spindle signals (On/Off, PWM) on a pinouts?

    Thanks, Mac!

    I stepped away to dig through a pile of surplus and found (hoo! ray!) a 6-24Vdc power-supply board I rescued from a dumpster!

    At the moment I plugged it in, I had a sudden flash...

    * 64-bit Windows 7 does not even detect...
