    well....Is messy alright, you need a strong vacuum a mask and gloves. Don't breath that stuff is nasty.
    I would suggest enclose the CNC in a acrylic box, so to contain the dust.
    It blunts tools in a hurry. Some tools are better than others but on average have a big supply.
    I don't have a CNC or a milling machine I do everything by hand, and let me tell you that I buy the drill bits by the box.:)
    I keep all the old ones and I will re-sharpen them. (someday)
    But I'm having and you will too.

    And a great filter on the vacuum I imagine! I've read that some people do manual cutting with water running over the part to collect the dust, so it never becomes airborne in the first place. I'm going to have to experiment with this tonight, I need to make an adapter plate to mount the gimbal to my airframe, and I'm not comfortable printing that. I'm not as worried about the holes I need to drill as I am about the cuts I need to make.

    Thanks, Bill. I hope the word you left out of the last line (inadvertently, I'm sure) is the word "fun" and not "conniption fits." :)

    So you use a vacuum bed to hold the part down and the usually approach to tool direction....

    What kind of cutters do you like to use? If you have any part numbers or favorite suppliers, I'd much appreciate knowing....I typically would get them from McMaster, but I've not tried cutting anything harder than wood -- so my CNC is already in a big box with dust extraction.

    Andy.

    The gimbal is lose on the vertical shaft. I was trying to balance it by moving the camera forward and I forgot to tighten it.
    Now is good.

    Thank you Howard. A bit more tuning and she is done. What I am trying to do is have the "follow" parameters on a switch so I can switch between Free follow and fixed follow.

    Well is like POI
    On free follow the camera will point in one direction no matter which way the copter is facing.
    On fixed follow the camera point wherever the copter points.

    Bill, did you get to fly? I got a quick test in, and, well, humble beginnings... The pitch control was way too fast for the camera operator (he's never done this before so there's some learning that needs to happen on his part too), and I'm getting a high frequency oscillation on the roll axis that I did with the older firmware; I have some tweaking to do! Endless tweaking.

    Looks pretty good so far. Why did you stop the video as you started climbing? What camera was this?

    Thanks Josh. The camera is a 5DmkIII. I just chopped the clip before it panned down to me :) Here's a continuation, you can get a better sense for the vibration issues left to tackle. I'm not sure whether the firmware and new settings are to blame, or whether the vibration damping on the new mount is dodgier than what I built for the two axis version of the mount. I can't wait to shoot and process some raw video with the new magic lantern raw recording...

    Please Steve, next time could you fly a bit further away from those green things ;-)
