Hello guys, I've been using this machine since March, if you are interested in something, let me know.

Are you using it for production sewing or for product development/prototype/sample making? How do you like it?

My concern is that it's the first generation of this machine and there could be weird software and hardware issues like there are on many first releases of anything.

"Raises Hand"

I live in the Dallas area. Lucked out this year.

We should all get together for a beer.

No issue, I love Juki. Was just hoping for some existing competition. This should hopefully kick Brother and the other sewing machine companies into high gear to come up with products with similar features, driving down costs, etc.

I would also love to have something like this in my workshop to build new product development samples because it could just make life easier.

My only concern would be servicing and maintaining this machine. All the new tech they add will break sooner or later. Hopefully Juki is training the dealers and independent mechanics in the US to service these machines and not just relying on the big factories to send their techs in for training.

Is there another machine out there that has the  "Learning multi layer sensor" for being able to go from thick to thin and back to thick layers?

Is there a competitor to this machine at the moment from Brother or anyone else with similar features?

I'll be cutting Laminated nylon fabrics, Tegris and HANK/Hypalon in the near future on my laser and currently researching options for a good Fume Extractor/Scrubber.

Interested in hearing what you guys are using for your Fume Extractors/Scrubbers on your lasers and lessons learned on their setup, maintenance, and if you would buy the same model/brand again if you could do it over.

How much did your Fume Extractor cost?

Laser Cutter Manufacturer: WEIKE
Model: LC1610N with Reci 80W laser tube and RD6442 controller

We have to use video to show our costing and pre-production team's how the product is built. The video shows things we just cannot translate well on paper like how the materials are handled during the sewing operation (We only video the complex projects...which is all of them so far this year).

We also make a powerpoint with sewing instructions and pictures like you mention, however the things we provide to the costing and pre-production teams are not what the production line sewers will use. Sewing process instructions will be made from the info we provide for the sub-assemblies during the production engineering process.

Our goal at the design shop is to make sure the costing team understands the product. Our factory team will identify better ways of sewing a product in volume when it goes into production engineering and revise the patterns to get better yields for cutting. The production engineering phase fascinates me in how they figure out how to make a new product in volume (production patterns, automated machines, better sewing processes, etc).

There is a program that runs on iPhones and Android called Reflector 2 that lets you mirror what you see on your phone screen on a second phone, tablet or laptop that should help to let me sew and shoot video at the same time smoothly.

I'm still open to better ways of doing things and different gear to use.

Iíve got a challenge Iím hoping the braintrust here can help me figure out.

Iím trying to find a better workflow to recording and editing sewing instruction videos of new products I've designed for our production team (I'm located in Texas and they are in Indiana). Itís taking a significant amount of time to transfer the video files to a computer, edit them, render them, and save them to a USB flash drive.

I need to figure out how to do this quickly. Saving time is the most important thing. This is taking a significant amount of time and energy. It's taking away precious time that I can be spending with my wife and kids.

How do you guys do it? I'm open to all feedback and recommendations.

My current workflow is:
* It's a two person operation: one person sews and the 2nd person records the video on an iPhone 6 at 1080P, 60 fps on a mini tripod.
* We use a program called PauseCam because it lets us pause the video without it creating separate video files like it does if we use the regular iPhone video recorder, however we may go back to using the standard iPhone camera record because it can be easier to edit multiple clips then having to find the right points to trim and split a long video.
* After we record all the operations, I transfer the video files using Airdrop (Bluetooth transfer proprietary to apple devices) from the iPhone to a Macbook pro.
* I then import the files into iMovie (editing software that comes for free with Macs). There I have to trim the video clips, move around clips, and insert pictures and text. Inserting Text in iMovie is a headache, it doesnít have an option for static text without some gimmicky effect. Everything else is pretty simple drag and drop.
* Render/export the video in mp4 format in 1080P. This can take 1 to 2+ hours and the files can be massive (14+ gig).
* Days and weeks can go by before I have the time to edit and finalize the videos with our current workflow. We can forget things or realize we have to reshoot operations and/or video of operations disappear.

Options Iím about to try:

Option A.
* Download LumaFusion on my iPhone to edit the videos (LumaFusion was recommend by a lot of people on Reddit).
* Record the videos and edit each operation before continuing to the next sewing operation on the iPhone with LumaFusion.
* Finalize the editing, add text, etc in LumaFusion before finishing the sewing instruction session.
* Render the video in LumaFusion and Copy the competed video file to my Macbook via airdrop and then copy the video to a USB drive to send to the production team with the rest of the technical data package.

* Uploading the video to youtube takes too long due to the large file sizes and you have to baby sit it incase there are issues. Our production team prefers a USB flash drive with the video so they can keep it all together in a 3 ring binder with the technical data package, notes, etc for each product.

Option B.
* Buy a small android tablet with a SD card slot and preferably a USB connection and a camera that can record 1080p at 60fps or better.
* Find whatever the best editing software on the tablet is and apply the same workflow as in option A.

Option C.
* Something better that someone here recommends.


* I'm try to keep everything as simple as possible. For example, we make a powerpoint with the sewing steps. When recording the video, we flip to the page on the powerpoint, record the page with the camera and then start that operation to record. If we find issues in the powerpoint, we fix them and reshoot the operation.
* The videos and powerpoint with the sewing operations help us to remember how to sew something after we have not touched it for a long time and our production team to learn the product. Iíll make the trip to the factory a few times a year to help teach our team new products, however I cannot make a trip for every product.

Things Iíve tried:
* I googled a lot and found some good info on Reddit. The recommended free editing software for PC and MAC is DaVinci Resolve. I tried it and liked it, however it kept crashing on me making it unusable. I may need to update my operation system to High Sierra (currently on OS X El Capitan). I liked how you can drop text on black background easily, importing video and pictures was just like iMovie, and rendering video was fast and simple to do.
    * If there is a magic device out there that lets me take the video, edit it, add text and render/save it to a finished video quickly I would buy it.

    * Iím also trying to figure out how to do all of this by myself where I can sew and take the video at the same time without a second person.
    - I still do not know how to setup a trigger or remote to be able to start and pause the video recording without having to physically touch the camera.
    - Iíd also like to find a way to mirror the screen on the iPhone or tablet to a second tablet, phone or monitor that I can mount to the sewing machine or sewing machine table to let me see what is being recorded (the area that is being recorded incase I need to adjust the lighting or the camera on the fly).

    Does anyone know of a US source for circular knit in coyote 498? We have been buying the velcro brand wide circular knit material (same type they print multicam on that is 8oz.

    Our current supplier, MMI Textiles, found the coyote circular knit they have in stock is not the correct shade (coyote 459) of coyote we need and they would need to run a minimum 600 yards to get to the correct shade (Coyote 498). We only need 50 Ė 100 yards for an upcoming job.

    Any help is greatly appreciated.

    Would anyone be interested in buying scraps and drops of Trelleborg toll coated hypalon fabrics?

    I can sell by the pound. All leftovers are from laser cut runs. Lots of small and large pieces. Perfect for pouches and larger pieces.

    Have coyote brown 498:
    38oz (Hi-Tear) This is like HANK but even tougher and Stronger for laser cut MOLLE applications
    35oz (Hank)
    18oz (Hank)

    Black
    18oz (Hank)
    35oz (Hank)

    Note that these are all CSM toll coated fabrics. We call them hypalon, however Trelleborg has not made them with Hypalon for a long time. It's all made with CSM.

    « on: May 07, 2018, 07:27:47 PM »
    I tried getting this stuff a while back from Murdock, however the minimums were like 3,000 yards if I remember correctly. We ended up just going with 1.5" wide multicam jaquard webbing instead.

    Thank you! I'll send them this picture.

    Materials science / Help Identify this plastic piece and it's supplier
    « on: April 26, 2018, 08:20:52 AM »
    Please see the picture below with the plastic piece circled in red. Does anyone know who to buy this from and what the part # is? I'm looking for it in a Tan or Coyote color.

    It looks just like National Molding's Slick clip. I contacted National Molding and they said it is not their product. National Molding said the Slick clips only come in black.
