Just to update on this, it wasn't directly a configuration setting, it was actually a blockage in the hotend (I suspect because the PTFE tube had become unseated from some black filament that was stated as 1.75 mm but I think it had a larger diameter). After clearing through my hotend with some PTFE tube, I found a disk of the black filament I initially ...

This is under extrusion, not delamination. Delamination is the result of the under extrusion. It typically happens when the wrong filament diameter has been set in the slicer (a larger diameter than used, e.g 2.85 mm instead of 1.75 mm). Another option is that you accidentally put the printer in volumetric printing mode which is accessible through the ...

Assuming that the model is sliced correctly, not scaled (by looking into the G-code you can find out if it is sliced correctly, look up the last layer move G1 Zxx.xx, xx.xx should be the height of the model). If that is correct, then your Z might have a problem in that the steps per mm are set incorrectly, or your Z stepper is missing steps. As Marlin is ...

Technically, you don't need the nozzle diameter. All you need is line width, layer height and filament diameter. After all, all the settings are just used to create a displacement of the filament feedstock (volumetric displacement). But slicers do use the diameter to set initial values for some parameters, e.g. the wall width.

I never thought about that! I do know from experience that Cura uses nozzle sizes to sanity check your settings, warning you if you do something unreasonable. That is reason enough to include the feature for me. However, I did wonder what, if any, differenced this actually makes, so I tested it and here's my results: I went through and tested it on the ...

I just flashed my new Ender 5 with Marlin and I had the same issue. The 2nd and 3rd layers were digging into the previous layers. I manually lowered the bed by 10 mm via the machine knob and the bed only moved 5.207 mm (I used a dial caliper). I went into the EEPROM and adjusted the steps/mm for the Z from 400 to 769: 10 mm /5.207 mm is 1.921 400x1.921 is ...
