    SMM moco

    Here is a thing Ive wasted much time on..

    FIRST REEL..



    Modular Moco rig which can take a camera or be used as a product spinner

    I love DIY moco! You're not wasting time, you're doing something useful and having fun in the process. That's how I justify my "experiments" in this area.

    Are you using Mantis for control?

    You need to get this material over to Doug Kropla for showcasing on his Facebook DIY Moco page...

      Im not using Mantis - never heard of it.. using my own rubbish app.. Ill check that out!

      Writeing an app is fast thinning in the amusement factor.

      I do hope to use it commercially so indeed not, I hope a waste of time

        Mantis is the go-to for turnkey indy professional moco... seen in action here...

        https://www.youtube.com/watch?v=sDzrfNepMTA

        It's basically a high frequency 8 channel CNC controller board, built out in a box with good I/O options, with a full custom motion control software written to run light on older laptops if needed. It will work with your steppers and existing drivers and make move programming fun. Or more fun. Or at least "fun-ish".

        Here's the site...

            Really, really, really cool. Well done. The "up and over" is fantastic.

              The 'modularity' is that one axis can be removed from the rig and set on a bench/tripod.. this will allow 'up and over' mixed with a product rotation.

              Not really a filming application but will allow basically a 3d set of photos to be taken of a product from many many angles.. a web shop tool if you get me as the user should be able to mouse over a product and spin it in 3 axes.. maybe its called photogrametry or something

              I need to hook up with some digital people and see what they can make of the raw footage

                  Love this! Would love to see BTS of the rig taking these shots as well. I've recently been getting into building Moco rigs myself though in the early steps (just getting done with learning how to control steppers with arduino and through dragonframe. Would love to know how progress is coming along with this. Would be curious to know what strength motors you are using as you are getting some really solid shots with your rig!

                  I've heard of mantis but also heard of people using dragon frame lately. I really need to dig into the differences but it's hard to find out details on them both it seems in a comparison.

                    The latest, still unreleased promo vid is here with some BTS. I release the video when I get the 3d render of the shoe back.
                    https://vimeo.com/340989485/8cb80facd1

                    I have nema 23 on slide and tilt

                    Pan is nema 17 in three formats.. straight, geared down and epicyclic.

                    I do have some issuses with backlash that was not properly adressed at the design stages

                    Bigger drive belts have more backlash.

                    Doing an oral B product shoot at the moment.. its OK but Im over budget time wise.

                      Hopefully Doug Kropla will chime in here, as he's built a score of fun, resourceful and innovative DIY moco rigs, and has a Mantis system as well as Dragonframe experience. I can tell you that Dragonframe is more stop motion focused, and Mantis is first and foremost live action focused, both with a large overlap in useful scenarios. Dragonframe is move and shoot only, unless you buy their "higher end" interface box, while Mantis can do live action, go motion and stop motion moco.

                      Here is a little demo of my first nodal pan/tilt/roll head from a few years ago, in which I gleefully lifted design elements from Doug's work. I'm using Dragonframe to run it, and doing a live preview "cheat" to make it look like it can slew all three axes simultaneously (well, it can, but only in one specific case which I'm exploiting)...

                      That design suffered from backlash due to the geared steppers, so I next went with some wonderful Harmonic drives I found on ebay and tried something with more camera and lens versatility in aluminum...

                      http://files.datausa.com/imageshoppe...CO_head_01.mp4

                      I'm still improving that rig, which is a stop motion only rig, and currently exploring a much more compact pan/tilt/roll design that is designed as small as possible around specific lenses camera configs...

                      As Morgan can attest, DIY moco is so much fun!

                        So speaking of moco, the great grandfather of moco systems, the original Dystraflex from Star Wars has been refurbished and made its debut at the Academy of Motion Pictures Arts and Sciences Thursday night at this event...

                        http://www.wearemoviegeeks.com/2019/06/266867/

                        That amazing Millennium Falcon model you see in the pictures is NOT the ILM original, but an exact replica built by a friend of mine, Sean Sides. I was lucky to be one of the first two fortunate folks to see it completed, and I recorded the evening as Sean does a walk-through of the construction process for us...

                        https://youtu.be/GpzW3t2wzXM

                        Since this is DVXUser, camera tech notes... I shot it with the GH5s on the Ronin-s with a Sigma 10-20mm f3.5, HLG at 2500ISO. It was one long brutal 28min take and a bunch of b-roll shot after my arm stopped shaking.

                          Aw good to know and thanks for sharing the samples. Yeah right now I'm just running arduino into a trial of dragonframe as I'm still in the early stages of testing and building stuff. Just learned about planetary gear motors today actually haha. Working on getting my hands on some 8020 Aluminum Extrusions now to be able to attach to steppers and build rigs for motion controlling elements in a shot rather than the camera itself right now, though now I want to make a multi axis pan tilt head for sure! But first I'm starting smaller and slowly moving up, been taking away what I can a lot from the Behind the scenes of Steve Giralt's work (minus the camera arms) https://www.stevegiralt.com/behind-the-scenes

                          And yeah I heard there was a way to cheat out motion with dragonframe but haven't dug deep into that yet since I only have one stepper motor to work with. I have a second one on the way along with some other goodies to build a box containing my drivers, power supply, and arduino to help keep things clean rather than a bunch of wires on a board out in the open haha.

                              That's a cool machine that does a lot.

                              Random side question if you feel like addressing: What's the story behind the pixel @1:17?

                              [I had to send an a6400 (Sony) in to get a similar looking artifact removed. It was red and mine faded in and out until it one day decided to stay burned in.]
