Well, except you both misunderstood why I do want to do this. But you've assumed a lot, and decided to boldly bash the idea.
Thank you for that not really useful opinion.
My "not real" hot end have no problem getting to 280C and keeping it that way. This is not an issue.
And no, Im not printing abs at 280+ ,) just tested if it will.

How about glass wool (not rock wool) I have it somewhere in the attic... Its supposed to be fine till 260 celcius, anyone tried it around 270?

Im going to insulate hy heater block too, and I was thinking about rock wool, or cork. ABS temps will be too high for the cork probably... What do you think?

I did not mange to make a shots worth looking at - but managed to mitigate the issue. I have set infill width to 0.75 (Thiiick) and infill not only looks straighter (thinner only on junction points) but gained also a lot strenght.

You only had two infill layers, consider that the extruded filament is only squashed where it crosses - all other area are basically printed with a missing layer.
That is why the infill looks so different.
Hi,
Thanks for replying, but that's not the case. I've been printing witn 0.3 nozzle for quite a while, and I do know how proper infill looks. I am aware that basically exce

Hello,,
I finally managed to get E steps and other stuff right (I thought), perimeters are printed nicely, top infill is okay, bottom layers also fine. All dimensions of the print turn out ok...
..but it seem infill somehow got screwed up.

Pictures attached, can anyone advise why it's so "dotty". It looks like its been spitting it out and then stopping extruding, till it mee

Guys, is it possible that I have wrong nozzle size set? I bought my nozzle from Chinese, maybe its not at all 0.3 mm?
Would it have such impact on the prints?

Hello .)
I tested same print today - this time starting with 0.9 multiplier, so just a little bit lowering the default extrusion.
I got prints with almost, but barely fitting plugs - but startin to show gaps between the lines. I find all of that weird, I get nice finish with not bad top at 0.95 extrusion - so 1.0 looks like its a little bit over extruded. But plugs start to fit lower than 0.88

Extrusion width: 0.4
Layer height: 0.2
Perimeter speed: 30 mm/s
External perimeter: 70%
Infill: 60 mm/s
Solid infill: 60 mm/s
Top solid infill: 50 mm/s
Travel: 130 mm/s
Its ABS, manufacturer suggested temp is 242 celcius / 110 HB. I found that around 240-243 it produces the strongest prints, bed 110 with ABS juice - can go lower.
I have to go out now, but tomorrow I will try to bump up extrusio

Hi imqqmi,
Well, I have gaps on 100% infill - for example on top layers. This is not a proper behaviour, right?
And layers are not adhering together almost at all - I can break these objects with two fingers .)
Gaps - take a look at these:
Could you post the link to your backlash post?
EDIT: Ok, I found it.
You write about pairing lines - I dont have any such on these prints. Not at all.

Well, it completed...
Result is messy, underextruded a lot. Very fragile, layers nod adhering at all (actually funny, they break with slight touch).
Maybe because Slic3r choose 0.3 extrusion width when set to auto?
...but the plugs fit well.
I will repeat that test with 0.4 extrusion width.

Hi,
Im attaching the picture of another test, sliced with 0.3 extrusion.
The holes/plugs dimensions are wrong as usual, the big angle is a little bit too small - but I think thats because of abs thermal shrinkage being bigger than my issue error.
The second image shows the object before (on the right) and after the calibration according to the youtube link from the post above.
Result is ver

Sorry for the confusion, checked the actual gcode, and I was printing that at 0.4 - this was set to auto back then, and with 0.3 nozzle slic3r set it to 0.4.
Thats a wade with 9/49 ratio.
I'll take a look on this video, and get back here with some test tomorrow .)
Thanks!

It looks a bit overextruded but otherwise print quality seems good. The single wall test seems problematic. What are the slicer settings? Is the automatic volume or pressure contrpl turned on? What retraction settings do you use? Is there any extra extrusion set after unretracting?
From slicer:
nozzle diameter 0.3
0.2 layer
perimeters-shells: 3-3-3
Infill 20%
speed 30mm/s for perimet

Imqqmi, thanks for the response.
I'm attaching a photo of few test prints from today:
1. 20mm cube
2. 20mm empty cube, walls 0.4 (testing wall width)
3. Part fit test.

I have entered the correct nozzle size 0.5mm (I have measured it to make sure it is as advertised). I tried calibrating the perimeter width using the guide on the wiki, but the problem persisted. I also believe slic3r takes into account the extrusion width so it shouldn't have an impact. Someone please correct me if I'm wrong, this is just what I noticed.
Here's all relevant settin

Hi,
Did you manage to work it out? I get the same behaviour with Yate Loon's D40SM-12C, they start to whine below 220 PWM
