Nozzle sizes on A10M

[wiwarren]

No not all are equal. Which is why I am still having trouble finding replacements (even just 0.4mm). I bought a pack of MK10 nozzles ranging from 0.1mm to 0.8mm holes. First, apparently the nozzle provided with the A10M is considered a low profile nozzle (Geeetech please confirm). The ones I bought I pushed on my previously leveled bed. After releveling I tried to print with 0.5mm, 0.4mm, and a 0.3mm nozzles. First, no I did not modify extruder feed and would prefer not to. The 0.5 did ok but I didn't like the detail (yes it cut print time some as expected). The 0.4 and 0.3 had issues with clogging. As for the 0.3, yes the filament came out and I liked the detail and smoothness I saw (yes print time increase a little). I started having issues with the print about half way through with the filament no longer coming out. I had to work with the head without a nozzle on to remove a clog. Comparing the inside hole of the one that came with the A10M and the replacement, the original has a smaller inside diameter than the replacement which apparently is better for mixing the filament into the single nozzle. The larger inside diameter looks like it would be more of a chamber than a pathway.....still looking. It would be nice if Geeetech would tell us where we can get them (and hopefully on Amazon).

Just came back and edited after more searching. Questions. I
1. What is the inside bore size? I saw some manufactures that listed bore size.
2. Is it "low profile" or better yet what is the size from the threads to the tip. I had my bed adjusted to the max with the set I received and had to have a 0.2 Z axis offset. Now paying more attention.

Maybe this part will give you the help.

Thank you! This will be helpful. I did buy some replacements from Geeetech and now see Amazon carries them.

As I wanted to try larger nozzles. I bought some MK10 nozzles for tests. The first test was quite successful. To reduce the nozzle volume slightly beveled the end of spare PTFE tube with a pencil sharpener, inserted into the nozzle and cut it to length. The Z offset had to be adjusted by 1,1 mm in my case and the first high volume low detail prints have been a success.
Yesterday I changed the nozzle back to 0.4 mm and the nozzle was easy to change and clean.

I don't own the A10M but the A10. Assuming the A10 use M6 (thread) nozzles the truth is that the digital caliper tell you they are something like 5.5mm . I have some M6 nozzles, spares, for a different printers and when you screw them they do "grip" only on the last half turn. I've solved buying original Geeetech nozzles so not that big deal but can't find different diameters, even if I don't use them ( i stick with 0.4 ) . Last but not least the "shape" on those nozzles aren't the "Bowden's" but MK8 .

2-in-1-out nozzle is M7

Looking for the nozzle bore depth dimension for A20M nozzle. Same as A10M yes?

The measurement i'm looking for is in green here. Didn't want to start a new thread since some drawings were already posted here. Can you help?

No that's not the dimension I've highlighted in green...
