    Hello everyone,

    here are some pictures of my DIY E3D Motion System and Tool Changer.
    Completely based on the open source documentation on GitHub.

    All parts are machined by me and my friend.
    There is still al lot of work to do, but the motion system and the tool changer are working.

    Here are two videos of the first tests:

    Thanks to Greg Holloway for his great design!


    Hope you like it.

    Hello @p3t3rp4nd4

    Congratulations for your work.
    Just one question, where did you buy the kinematic coupling components?

    Tks

    Thank you all!

    @amagro the most parts were machined by me and my friend. The standard parts i found on the internet. If you tell me what parts you are looking for, i could provide you the links to it.

    Hello @p3t3rp4nd4

    The parts that I'm interested are the threaded balls.
    Btw, is there any change that you could share your CAD file with all the printer components?
    Thanks

    Congrats again for all your work.

    I used standard ball bearing balls i bought on ebay.
    They are installed with an press fit and a drop of glue for the fear.
    It seems to work well, they hold up very strong.

    Just installed one of the last missing parts, which @Julian1991 and i have machined yesterday.

    While waiting for the lasercut parts to arrive, is spend some time setting everything up and go for a little testing.

    Hi Greg,

    thank you!
    The missing parts should arrive next week, so the first prints should be done at the end of the week!

    Also I ordered an Hemera and I am very exited seeing it print on the tool changer.

    Thank you again for your great design and the support!

    Today i recieved some missing parts and could install the tools.

    3.jpg

    Also did the first toolchanging test with all 4 tool.
    Needs a little fine tuning though, but everythings works.

    Toolchanging Test:


    Now only the bed is missing and then the first print can start.

    How long you have to wait? And what bed you use?

    The last parts are installed and the first print is done.

    Printed the Benchy which came with the firmware and for the first print, it came out really nice.

    First Print:


    The ball screw works really well, because of the 4mm pitch the movement is pretty fast and also looks really smooth.

    For the bed bracket and the base plate i used lasercut 3mm stainless steel.
    The print bed itself is milled out of a 5mm precision aluminium plate.
    The bed heater is from Filafarm, it´s 230V and 450W, controlled by an Omron ssr.

    I also installed the paneldue and an emergency stop button, because i like hardware buttons ;-)

    The next steps are installing the raspberry camera, the calibration of the toolheads and than the first multicolor print....

    Thank you!

    The LCD case isnt´t my work, i downloaded it from thingiverse, only the attachement to the frame was made by me, as soon as i got a final version i am going to provide it.

    Paneldue Case:
    https://www.thingiverse.com/thing:2896405

    The housing for the emergency button was desgined by me and also needs a little fine tune, but than i will upload it to thingiverse.

    Great work.

    But it looks like you will run in to collisions between the tool head an the ball screw when you printing on the boarder near to the ball screw.
    Have you tested this?

    Thank you all!

    The ball screw is now 50mm shorter...
    Unfortunately I had to learn this the hard way ;)

    But thank you for the hint!

    But I don't know if this differs from the initial design. It think the screw is at the same position
