  • I was looking for automtion that turns off the speakers, but I could have the same approach for turning them on.

    If I understood correctly, that triger would be active at any state change (from on to off, from off to unavailable, from off to on, from unavailable to off) and then using IF ChromeCast is off it would activate automation even when it changes from unavailable to off. That wouldn’t solve the issue, am I missing something?

    I want it to triger when changing from on to off only, while ignoring change from unavailble to off.













  • I agree, its not even worth to try imo. Frame geometry is super important. Even extrusions can be painfull if they are not cut well enough. If you want the best result you should mill them (instead of cutting them with a saw).

    3D printer tolerances are far from acceptable and then every material shrinks differently (+ there are many other disadvantages).

    On the other hand, prusa and voron are examples of great use of 3D printed parts where you benefit from flex. Its a brave design decision that works amazingly well, but they can barelly print first layer without ABL or simmilar. Yeah…ABL compensates for shitty tolerances and we end up with bent 3D printed part that counts as perfect print lol



  • Idealy you want a server that runs all the time and some kind of a player connected to projector for streaming. You can use your rpi for server, but NUC sounds better since it probably has SATA or m.2 port for storage. Raspbian or Ubuntu doesnt matter much since both are Debian based and setup should be simmilar. Look into servarr if you are interested in automated downloads. Then get Jellyfin for Netflix like experience with your local library. Most clients support Jellyfin player and Im using android TV stick. I have just ordered ChromeCast with Google TV 4K to replacce my old 1080p Xiaomi TV stick. You can also install Netflix app on any Android device.

    It is also possible to plug your server directly to projector via hdmi, but then you have to install server apps together with client apps on the same machine. I guess you need a wifi keyboard and mouse for remote control. Having 2 devices is better IMO, but it should work as single device.

    Rpi or NUC can also be used as a player, but got no experience in setting that up and Android box is better solution for me anyway






  • I see the mesh, but cant tell what is wrong with it. Is your mesh about the same every time after running ABL? If you check any point on the right side, do you think your bed and nozzle are at the same distance after every ABL run, but sensor reading is wrong on that side?

    Basically you have to identify is your sensor faulty, otherwise your bed or X gantry might be moving in Z over time. Faulty sensor can be fixed or replaced or just go to manual mesh leveling.

    I would try probing the same point multiple times in a row and see what difference you see in readings. You could also do a manual mesh and compare it with auto bed mesh.

    Move nozzle close to the bed, disable XY motors and move nozzle around while observing the gap. 0.1 mm variation can be seen by naked eye (alternative to paper method) and you have 0.6 mm according to your mesh.

    Use a metal ruler (or something flat) and a light to confirm how much and where is bed bent, again visual inspection.
