    Great Build @Roy Berntsen ! Great large 3D printer. I also really like the idea of belted Z to remove any lead wobble from the system. How do you keep the bed from lowering when power is off?

    @Roy Berntsen
    Cool design. :thumbsup: I look forward to looking it over in more depth after work tonight.


    Have you seen the z-axis electrical brake from LulzBot "Here"?

    Looks like a nice solution to a belt driven z-axis.

    I use a 1:20 wormgear to hold the bed from falling. It can take a party on the bed nothing happening

    Believe me I have been though most solutions for the belted Z as did the designer of the KISS CoreXY as is the inspiration for this design and we both found the wormgear being the simplest, easiest and reliable solution. Its only downside is that it is not easy to find a supplier with a reliable tolerance scheme for these gears. We are currently researching some from misumi with a lower module

    My current supplier is a Chinese on AliExpress and they are not always good

    I agree the worm gear is a great simple solution. I like the idea of the break as well and I could see that being helpful along other axis to maintain position, but on the Z you will always have some drop, so I think the worm gear is a better choice.
    There is a company called stock drive products and they may have anti-backlash worm gear solution that may help.
    Great machine, keep up the good work! :thumbsup:

    Roy, I'm interested in the control panel (iPad?) that you are using. Is it connected via bluetooth? What app are you using? Since you are using Merlin I guess that is supports this setup.

    Hi!

    I am running the printoid app controlling octoprint from a tablet. Search app store or play store for printoid

    Hi Mr! I do have a X carrier for the e3d Chimera/Cyclops but this has not been tested
