    • I have an Ender 3 Max Neo, and I print via USB often.  I'm running macOS 13.2.1 with Ultimaker Cura 5.3.0-beta 2.   Every time I'm done and unplug my printer, I shut the printer down, then, the next time I boot it up & home it on my printer, it seems like the printer will ignore the ABL sensor and keeps pushing down on my print bed, making huge grinding noises, then after a few seconds, it goes back to normal.   It only happens the first time it home after I unplugged it from my computer.   I don't exactly know what's going on.  Firmware issue?  Or some software incompatibility?   Thanks.
    • Usually it's not the sensor but instead is related to the middle fan.
    • Note that the 14mm is a good position for the rear screw (and initially the front screws) and you shouldn't ever have to touch the rear screw again for basic leveling.  For very advanced on-the-fly leveling, I adjust all 3 screws equal amounts quite often.  But only if you disable active leveling and only after you have done 100 prints.
    • Using Cura 4.13.1 and printing with a 2mm nozzle.  Trying to print out a small part and having problems with the support (and the print in general).  Basically the support is getting fused into the structure.  Won't separate easily and the smaller details are clogged with what I assume are portions of the support.   Attached photo shows some of the problem area.  No separation between support and structure.   Previously did the print with Cura 14.07 or 3.xx (cant remember for sure which one) and it came out almost perfect - and, of course I deleted that file when I upgraded to current Cura version.   Sooooo many settings 😞  Any thoughts on where to look to resolve?   Also attached (assuming it will attach) is my Project File.     0.2 pla snap lock bottom.curaproject.3mf
    • Hello to all. I opened the 3mf file that @Carbon posted and that model has errors.  I repaired it with MS 3D Builder. The posted model is on the left and the repaired model on the right.  Cura shows the internal errors highlighted in white. (I ALWAYS check models for errors before putting more time into a project. Here is the slice.  You can see that the bottom of the lever is supported and there is a support interface to hold it up.   There are about 73 support settings.  Most are general settings.  In this next screenshot you can see that the pull-pin is supported on the bottom edge.  There is also a support that grows to support the pull-ring when it comes back together further above.   I would make a couple of changes to the settings here, but they would be personal preference rather than something being "off" with the current settings. I like a denser Interface when a print starts with a very small patch on top of support. With 2 walls and lightning support, this model will be very weak and the leaves of the pineapple may fail do to a lack of base material.  The errors in the model are right there at the base of the leaves as well.  That isn't good.   I've printed models like this and the "lever" of the grenade will be very weak and a failure point if someone just picks it up to look at it and squeezes it even a little bit.  I'd go with Grid infill at about 10% density.
