    Some more progress...I will probably change back to wood for further experiments. The engraving bit does not last very long in that brass alloy, in spite of very conservative feed and depth of cut.
    The text has nothing to do with the guilloche and is more a test of how much detail I can do with my machine. It is only 0.04" tall and barely readable. At that size it would need a clearer font and probably should better be engraved at constant depth instead of Vcarved.

    Playing again Gert?
    What brass? 360?
    Smallest font legible here was .08" with a 30 degree in Franklin Demi, but that was Maple.
    Didn't help that you stuck it on a Archimedes? Spiral!

    Absolutely!
    The brass is 260 alloy and not that great for machining but that is what I had.

    Had to look up 260 Brass thinking it may have been a typo.
    Yep, Great job with what you had on hand! Good thing it wasn't "Naval" Brass...Seem to remember Brady mentioning it was a No-No?
    "In its half-hard condition, 260 Brass has a machinability rating of 30 as compared to 360 brass rated at 100. "
    Just adding this for people as ignorant of Brass as me.

    What angle bit did you use? Engraving? Flat?
    Keep playing!

    Just getting back into this program G.
    Not getting Exactly what I want yet, but then only opened the instruction .pdf for the second time this morning.
    Almost hit or miss at this stage, and the OPTIONS!
    Still too busy for a 1" button border, but just started playing with using only portions.
    Early days.
    Thanks again.

    Wow. 3 years ago since I last worked on the Guilloche project. But I picked it up again (retired now, yay...). I think it is promising; I improved dxf vector output capability and added rotary axis support.
    Also got a 120 deg. diamond drag bit, made a spring loaded holder with linear ball bearings and tested that on some household items. Not bad for a first attempt and working with that diamond bit is easier than I thought.

    Engraving the bottom of a tumbler glass:


    Still need to fine tune the pressure, but no serious chips. Took only 3 minutes to engrave:


    Inside view:


    Engraving hardened steel (Chinese butcher knife/hatchet). The lage pattern is 2" diameter, the small one less than 1/2"

    NICE Gert

    Just downloaded it again, and it was the same as already on my Desktop.
    Is Guilloche0_92 the most recent version available?
    Need to play with it again...may just add a pattern to one of the Bespoke 33 children's blocks I'm finishing up on now(18 of the 132 cube faces left to go
    The diamond drag work looks beautiful!
    scott

    Never did put a button into a production run, as everyone had a different favorite, and we couldn't agree
    Only a couple got rough protos carved

    Scott, I am still working on the new version. That software has so many options it takes a bit of time to test and debug all of that. Please hang in another week or two and I will let you know when available. Eventually I want to be able to use the indexer to engrave or carve a guilloche pattern on items that have variable radius like the outside of a wine glass, a pen or a tapered cue.

    I clicked on the "shopbotograph" link and got warnings from my security software about malicious code on the site. It seems to have been compromised. I wouldn't advise downloading it.

    Norton has been calling SB site dangerous for years-a total error on their part.
    Not their only one I have found. Tends to happen more when using Explorer than other Internet software.
    Further comments on this subject are welcome on a NEW thread-Leave the rest to Gert's program now-Thanks!
