    Nice printer :) I have the same in full black ;-)

    Do you have bed tilting betwin front and back compared to the center of gravity made by the leadscreews ?

    I moved the lead screws to center to match the new center of gravity.

    Me too, but still have have instability cause by flexibility of Z motor holders, and flexibility of 2020 Z extrusion (well bolted), only when I use Z hop, perfect without.

    I just started one of these myself. Curious about the second power supply. Is it just for the bed?

    yes he talks about that I think 1 video back.

    Maverick
    Seems like this kind of design has a couple of problems.
    First one is it's not very rigid you have seemed to solve that problem with new corners.
    The z axis seems to give people problems.
    I have seen many people move the z linear screws to the center of gravity and that seems to mostly fix that problem.
    In your next video could you put some kind of indicator on the bed and flex it a bit, so we can see how much flex there is?

    One last thing I llike the build and talk style of videos you did on other topics, this series you are more showing what you have done after the fact. more building!!! LOL

    thanks for the hours of entertainment though...

    Maverick I saw the answer this weekend at MRRF.
    use a c-beam on the back for the z axis. I will post a like to a video as soon as I get it done.

    spauda01 here
    Saw your 3-27 video, hooray for stock config :D
    You're right about not leaving enough room in the control box for lcd adapter, I either connect to pc or to octoprint.
    If you let me know how much wider and taller you want the box I'll post an updated version.

    What is the marlin firmware that you have. I have also built a 300x300 machine but I can't get the steppers to rotate, they hum and get hot but won't rotate. I'm not sure if I have them wired incorrectly but everything was followed as the instructions. If you don't mind sending me a copy of your marlin configuration. And if possible pictures of the motor wires and ramps wiring that you have
