    So if you've ordered a Dual, as I have, what's the point of installing the IR sensor?

    You need a Z-axis end stop.... I think that's why...not an expert....yet ;)

    Yes, the sensor is simply a z-stop. I converted my Pro to use mesh as the sensor does not really like the black and white bed.

    Well, I have to admit the bed is a lot more stylish than the usual red thingy.

    ...sorry to hijack your thread, PsyVision. :confused:

    Meant to reply to this yesterday. I think this cube was before I calibrated my steps/mm. This was running at 50mm/s with the new acceleration settings in the firmware. When I have some time I will try another cube, double up the height and run one half at 30mm/s and the other at 50mm/s.

    On the whole bed levelling thing, this is a slice from the Marlin firmware configuration file:

    Code:
    // There are 2 different ways to specify probing locations:
    //
    // - "grid" mode
    // Probe several points in a rectangular grid.
    // You specify the rectangle and the density of sample points.
    // This mode is preferred because there are more measurements.
    //
    // - "3-point" mode
    // Probe 3 arbitrary points on the bed (that aren't colinear)
    // You specify the XY coordinates of all 3 points.
    
    These are both auto bed levelling (ABL). So what you are seeing in the video is probably the grid method with 9 points specified.

    I think the difference is that the ABL methods (both of them) will just create a plane that is the bed, averaged through any points it measures. This will treat the bed as 100% flat. However, the (manual) mesh bed levelling will cope with a bed that is not 100% flat (i.e. slightly curved glass).

    Ah, I see, thanks, I thought I must be missing something. So what isn't supported is automatically probing for the mesh levelling.

    See here, looks as though there is some code available although not ready for prime time:

    Here are a couple more shots of the Benchy:

    Here is an in progress photo of a stand for HTC Vive VR controllers, it was under extruding earlier on and needs a bit more outline overlap.

    Lovely prints.

    Can't tell if that's the extruder or just your exquisite dialling in.

    At least we can say that the Titan has not screwed things up!

    I think there's definitely been a step up in quality switching to the Titan but there's definitely more quality to get out of it. I've barely spent any time getting it dialed in, hence the issues with the Vive controller stand. First few layer quality is abysmal on that print, I will be switching back to mesh leveling soon.

    Can you put a finger on where the quality improvements lie?

    For example, the "seam" in the bench looks kind of neat. Like maybe snappy beginnings and endings?

    The z-scar isn't too much of a problem for me, but it has some weird marks on the side in the first image, admittedly hard to see. It is also under-extruded, as is the vive stand.

    Benchy isn't meant to be an easy print but I think it's handled it well. I am, typically, really harsh on the quality of my own prints.

    A little in progress, now running on Marlin RC5 with mesh leveling again, thanks to @Alex9779

    Why/How is that model printing with no support? I'm puzzled.
