Hello all, I have been messing around with settings in skeinforge and improving my print quality, However, I can't seem to get the quality the same as the parts that came in my kit, a Mendel There seem to be little missing gaps at the beginning of each layer, and as per the photos, not perfect fill Can anyone recognise what I have got wrong Many thanks in advance Myles Reprappro Mendel, PLA 1.75, hotend 190, bed 60 https://reprap.org/forum/read.php?262,166662,166662#msg-166662 Wed, 13 May 2026 03:21:56 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,166662,167026#msg-167026 https://reprap.org/forum/read.php?262,166662,167026#msg-167026
About the same, maybe a little less surface quality at 10mm/s, can't go much faster without printing multiples for additional cooling time at this scale.

With my hot end, a Wildseyed variant, and at this scale, printing faster gives me lower quality, even with a fan running. At a faster speed the layers do not have enough time to cool, and the subsequent layers start dragging and distorting the previous layer.

I'm runnning .05mm prints at the bottom end of my ABS temp at 210C. I normally run .2mm layer prints at 230-240C, 30mm/s.]]> Dirty Steve Printing Mon, 19 Nov 2012 19:40:29 -0500 https://reprap.org/forum/read.php?262,166662,166999#msg-166999 https://reprap.org/forum/read.php?262,166662,166999#msg-166999
When you go down in layer height you need to increase your print speed. This is because of the melting rate of the plastic, it needs to melt a minimum amount of plastic per second or you end up printing with ooze from the nozzle not extrusion.]]> Sublime Printing Mon, 19 Nov 2012 15:30:40 -0500 https://reprap.org/forum/read.php?262,166662,166979#msg-166979 https://reprap.org/forum/read.php?262,166662,166979#msg-166979 Dirty Steve Printing Mon, 19 Nov 2012 13:03:48 -0500 https://reprap.org/forum/read.php?262,166662,166977#msg-166977 https://reprap.org/forum/read.php?262,166662,166977#msg-166977 I wish you all the best with your improvements , I guess the finer one tries to go the more complex the settings get.
Good luck and thanks for the help

Working on printing smaller currently, I'm running into either z-wobble, layer smashing due to temp expansion between bed and hot end, varying feed matial quality, or a combination of all 3, producing some layer banding. The ridges in my prints are several layers thick, thinking z-wobble mostly.

Here is a pic of my test prints, Pink Panther Lady, printed at .05mm layer, 5mm/s feed rate, 210c with ABS.

Print in blue is .1mm layers and 50mm tall, one on the right is .05mm and 20mm tall(400 layers), and on the left is .05mm and 10mm(200 layers) tall but not completely dialed in because the radiant heat is taking away some of the detail.

Also working out the vertical banding, mostly in the blue print, which I think is coming from my T5 belts, switching to T2.5 soon.]]> Dirty Steve Printing Mon, 19 Nov 2012 10:47:32 -0500 https://reprap.org/forum/read.php?262,166662,166958#msg-166958 https://reprap.org/forum/read.php?262,166662,166958#msg-166958 Many thanks for your advice, both your posts contained massively helpful info,
I am slowly getting my head around the settings, after taking your advice I reduced
the above settings to match my .5 nozzle and with a big decrease in extruder feed rate,
I achieved great prints.
The only drawback is the increased print time, but with your .25 nozzle and your settings,
you must be able to get the most amazing detail prints. If you have time I would love to see a
photo of the sort of detail you must be getting.
I have since tweaked my settings back about halfway to what they were and am very happy with the results.
I include 2 pics of the latest print which I feel is of equal quality to the parts in the kit.
With your help I now feel I understand the settings a lot more and will reduce the settings for more detailed prints
Many thanks for your help

You may have to tweak your flow rate a bit, but overall I'm getting better results.

I'm running a .25mm nozzle, and get an 'in air' extrusion width of .33mm, but I get much better path to path overlap and stronger parts using .25mm for extrusion width in SF.]]> Dirty Steve Printing Sun, 18 Nov 2012 12:08:25 -0500 https://reprap.org/forum/read.php?262,166662,166699#msg-166699 https://reprap.org/forum/read.php?262,166662,166699#msg-166699 Bit of a noob here, is extrusion width called something else in skeinforge ?
I have .5 nozzle with . 3 layer height and get quite nice .5 mm walls ?
My prints are improving and now quite functional, but I would like to pretty them up a bit
Appreciate any help
Many thanks

Example, if you have a 1.5 mm wall, and an extrusion width of .6, the perimeter passes will take up 1.2mm leaving a .3mm gap that your slicing software will not infill due to the infill space being smaller than your extrusion width.

I've been running my extrusion width to be the same as my nozzle diameter of .25mm and tweak my extrusion rate accordingly.

I still get gaps here and there, but very small.]]> Dirty Steve Printing Sat, 17 Nov 2012 16:06:46 -0500 https://reprap.org/forum/read.php?262,166662,166662#msg-166662 https://reprap.org/forum/read.php?262,166662,166662#msg-166662 I have been messing around with settings in skeinforge and improving my print quality,
However, I can't seem to get the quality the same as the parts that came in my kit, a Mendel
There seem to be little missing gaps at the beginning of each layer, and as per the photos, not perfect fill
Can anyone recognise what I have got wrong
Many thanks in advance
