    I built my own ATC Tool Carousel, would anyone be interested in me open sourcing it?

    Hello!

    I recently added an ATC spindle to my CNC. I quickly out grew the static tool posts that came with it.

    When I looked for a tool carousel I couldn't find one that was affordable and my controller box was out of space anyways.

    With all of that I had to think outside the box!

    I ended up building a very robust 10 slot tool carousel with some neat features. It didn't take long before I started getting requests from people to build them one as well.

    It would be a shame to leave all this work in the shadows. I wanted to reach out to you folks here and ask if I should take the time and energy and open source this project?

    If you are interested I have posted a video to youtube (first time for everything!). It is of the first prototype working and should give you an idea of the level of quality it offers even in its infancy.

    If you like it I will start putting together the resources, instructions and maybe even make kits. Please watch the video and "like" it. I will judge the interest by comments here and on youtube.

    Thanks!

    Can't see a lot in your video but what I can see looks great! You could post your files on github at no cost you you. What spindle are you using?

    I was measuring the lift off and seating during operation of the drawbar in that video. I need to get the system cleaned up and better video made of it.

    I use GitHub a great deal, but the time it takes to get this stuff up there in a usable form will be the real challenge.

    The spindle is CNCDepot.net's S30C. Nice little 3hp for non-ferrous materials. The tool carousel is ISO30 but can be easily adapted.

    Looks like a nice changer. Lots of peole woud like plans and the macro. Are you running Mach3 or4?

    Nice system and great display of the advantages of 3D printing. Love the way you took the simplistic approach to "concept" and the follow through in execution. If there were a way to use TTS tooling with some type of drawbar system, I would jump in a heartbeat for my router. However, you system just satisfies a major part to the ATC formula.
    Thanks for posting and hope to see a follow up to your system.
    Stay Safe.

    I am running Mach4 but it would be easy to port to Mach3 and LinuxCNC. I have decided to shoot for end of June or early July for release to github. I am making a custom PCB to simplify the electronics.

    Thanks for the input! Once I have this out we can start looking at other systems to integrate with. Keep in touch!

    Is it static in place or does it move, besides the rotating? My machine has a linear tool rack and I have room for up to 10 tools but I am giving up several inches of my work table for the rack. I'd like to go to something that will give me the table length back. It looks like a nice rack though.

    Same here. If it retracts from the workspace then I gain about 8" inches back on my 5'x10' machine. I paid for that workspace and I want to use it. That is what was killing me with static posts. I have a 8 foot A axis that I have to remove to get 10 tools comfortably on my machine. I have the added problem my machine is dual process (spindle and plasma) so I have to remove them to place the water table on the machine. The point of having two Z axis was speed of switching between processes but the static tool posts or the carousel protruding into the workspace causes problems.

    The response to your question is IN PROGRESS and HIGH priority. I just got through talking to the worm drive manufacturer. They have a linear drive system that I could use so now comes the engineering issues with moving that carousel out on an arm and having the spindle collide with it and it not flex.

    The added cost is going to be high :-( but is probably worth the extra cost.

    Then there is the dust shoe! Argh! Metal chips is one thing, blow them off with a vortex cooler but wood dust? Gotta vacuum that stuff up. It aint ATC if you are having to manually remove the dust shoe for tool changes.

    Add me to those interested in you Open Sourcing as much as possible.

    I have a Hurco Bed Mill that I converted and would like to do an ATC,
    and it looks like you have done things quite nicely so far...definitely need
    to have the ATC retract away from the Spindle...

    Looking forward to further post.

    Best Regards,

    Preston

    Preston,

    Cool! I just got through installing Alpha 3 as I am calling it. I have replaced all of the 3D printed parts with plasma cut components. I will make the 3D printed one available put it doesn't age well.

    Since I am out of space on my controller I am slogging through a lot of software to add motion and sensors. At this point I am really bogged down writing for this awful Mach4 software product. Lua has to be the absolutely worst scripting language ever invented. Makes Python look pretty by comparison!

    I will probably release the design, DXF and STLs before I can have the PCB, software and kits available. If you have space on your controller then you will be in luck early.

    Anyways, here are some images for the Alpha 3. I might replace the birch playwood with a 3/16 or 1/4 plate with threaded holes. I kind like how the plywood will distort and return to shape. Makes small errors in the tool change process not damage your very expensive spindle!

    Interesting. I'd like to help you manufacture and distribute your product when you are ready to go prime time.
