laser etching over a curve


  • Developer of T2Laser Software

    @tug Most of the 3D printed solutions use a lathe type chuck which can hold inside or outside various shapes.



  • chuck design, yes have exactly the same type to print, once I have a working unit will photo it and show you
    the ali profile is exactly what i'm looking for well done buddy

  • My version of a rotary axis simply changes the X linear motion into a rotary one with the driving rollers having the same movement per motor step as the A3 Pro. For such items as glasses the pressure roller can go inside and for plain cylindrical objects on the outside. No calculations needed only decide if the design will fit on so measure round with a tape. As far as the A3 is concerned it is the normal X axis, has the same motor and plugs into the X axis socket. One thing I will mention is the Z axis adjustment was far too little so I had to make an adjustable slide to raise the laser up by about 80 mm to get focus on my intended maximum diameter and flat items and this in turn required me to increase the height inside my enclosure.

  • My efforts at keeping it simple but effective, not quite finished but almost.1_1550750454971_DSCF8659.JPG 0_1550750454971_DSCF8658.JPG

    just have the chuck to finalise on design them print with £d printer, will post pic on completion.

    @tug That's awesome, I like how simple you kept it but it looks really functional too. With 2 sets of the guide wheels and a multipurpose chuck I would say you have a winner!

    Hi Tug,
    There is a unit available - my business makes them & is in process of a crowd funded global launch - price in brackets below.
    It will accept glasses of all sizes - champagne flutes, wine or beer glasses, bottles & other tubular objects to 40cm long.
    Has a gear reduced motor drive, outer frame to make it post-proof & options to fit a solid state 2.5 watt / 2500mW laser & EleksMana board.
    the X-Carriage will also adjust for tapered glasses & bottles, so the laser will remain in focus on tapered pint glasses etc.
    Sliding clamp to secure parts internally or externally secured from 30mm dia > 100mm dia.
    £260 (£180) without laser, or £330 (£300( with 2.5 watt laser & mother board... + post outside UK.
    Includes eye protection shield, rubber feet & ready assembled to work out of the box.
    Built from Black Anodized Extrusion / Green Translucent Acrylic.

    Not wanting to breach rules or advertise here, but happy to assist if you want one.. or parts description & dimensions/materials to build your own from what ever you have laying about.

    If of interest, pictures to follow when i get back to work in a week - on holiday at the moment.

    I paint the glass with water soluble paint, then wash it off on completion.

  • you have to elevate the machine to enable the laser to focus on the object your etching, but this can be done as you can see using boxes or maybe a stand.



  • Very impressive looking rotation unit, & the simplicity makes it even better



  • I've been considering doing this type of thing for a while now, but it looks like you have a nice, clean, elegant solution.

    I'd like to get info on how much it would cost to ship this unit to the US (San Antonio, TX). I have the laser setup already.

    Thanks!



  • I am happy to charge £20 for postage to the USA and if it's more I'll cover that so trying to make it as economical as possible, however the raw materials including the step motor are not cheap.
    If anyone would like to place an order I can ship within the week. please state if you want flat pack build it yourself of ready to run. with the minimum of fitting.
    Thanks. Tug



  • OK they are now ready for ordering, the length has been adjusted to cover most items you would ever need to etch on a round surface.
    I can supply them flat packed or assembled.
    Flat packed will cost you £86 or $ 112 plus postage from what ever country your in please ask.
    Assembled will be £93 or $122 plus the postage as above.
    Dispatch will be within two weeks from order, delivery is out of my hands so depends on your location.
    if there is anything else you would like to know please either post here or email me at: tugwilson206@gmail.com.
    Thanks for looking.6_1551707815526_laserjig-7.JPG 5_1551707815526_laserjig-6.JPG 4_1551707815526_laserjig-5.JPG 3_1551707815526_laserjig-4.JPG 2_1551707815526_laserjig-3.JPG 1_1551707815526_laserjig-2.JPG 0_1551707815526_laserjig-1.JPG



  • To clarify the rail length has been increased from 20cm to 35.7cm this is not shown in the photos. but every one will be at the new length.

    these pictures show the parts involved except the step motor which I am awaiting delivery of, you have everything you need to have a simple inexpensive unit for etching tubes, glasses , flask's and many more items.



  • this picture shows all the components you will get with the unit, you will see that some parts are assembled so as to make your life a little easier.

  • yet another exsample of the versatility of the rotary add-on unit.0_1552719209307_IMG_20190315_171414.jpg

    Note the rollers are on the sides and if the arms were crossed over the size of the object to be laser etched would be that much greater

    I now have a unit in stock for immediate delivery.



  • Any chance on you releasing the STL's for the printed parts? :D
