How does the sizes of nozzle diameter and the Z-axis layer resolution work?

Yes, they do reduce the speed. Basically, the speed at which you feed filament determines how large of a volume comes out, and the distance you move the extruder means this volume gets distributed ...

Can you print at 0.3 mm with a 0.2 mm nozzle?

To get the best results, the plastic coming out of the nozzle needs to be squished/ironed down by the nozzle. If you are using a higher layer height than nozzle size, this does not happen. Instead, ...

Is it necessary to have both hot ends on a dual extruder printer at the same height?

I have a dual extruder Replicator 1 and having the nozzles at the same height is a must and albeit a bit of a struggle otherwise. At one point, I had to disassemble my extruder head and the nozzles ...

Does the Creality Ender 3 allow variable layer thickness?

Variable layer height is a setting of the slicer, not an ability of the printer itself. However, the printer must be able to print at such layer heights. Any FDM (Fused deposition modeling ) or FFF (...

Do I need to recalibrate z-probe offset every time I switch to a different layer height?

All modern slicers adjust the nozzle position for the first layer in accordance with your chosen layer height. You can see this in your gcode if you slice files with different layer heights. Before ...

How thick is 0.1 mm?

What is the thickest sensible layer height that an Ender 5 will print at?

Your maximum layer height is related to the nozzle diameter. Typically, a printer is sold with a 0.4 mm nozzle diameter, unless otherwise specified. One expects to be able to print safely to eighty ...

Is it necessary to have both hot ends on a dual extruder printer at the same height?

I don't have dual extruder printer myself, but to my understanding having both nozzles leveled at the same height is critical for getting successful prints. For typical FDM printers, the lowest point ...

How thick is 0.1 mm?

Maybe a better way to visualise 0.1mm is to explain that it only becomes really visible on a shallow slope. A 10 degree slope will place one layer boundary every 8mm, and these steps will probably be ...

How specific can I get setting layer heights?

Layer hight can be theoretically anything as long as it fits into these ranges: it needs to be at least one step for the Z-Axis motor to be physically possible it should be at max 3/4th of your ...

Print limitations with 0.4 mm nozzle

Yes, absolutely. I believe the original sample file that came with the Ender 3 (0.4 mm nozzle) was sliced for 0.1 mm layer height. As long as your printer can get decently precise Z positioning at 0.1 ...

Are thick layer lines easier to sand and fill than thin layer lines for low detail objects

No. The outside of the layer has a round cross section, so the higher the layer, the larger the semi circle cross section and the deeper the valley is between layers. Fine layers take forever to print ...

How specific can I get setting layer heights?

You decide which layer height you want based on the quality you desire, but never go over about 75 % of your nozzle diameter, so with your 0.4 mm nozzle never choose layer heights larger ...

Your Z axis movement is somehow wrong. You should check steps/mm, z acceleration and speed. Try moving your z 10cm up and use caliper to check if it is correct.
