Hi All, I was hoping I could get some input with my prints, I'm very new to this. When printing it seems as if my extruder is dragging over the print and I'm not sure which setting to change to resolve this, I'm using Slic3r if that helps. Thank you, https://reprap.org/forum/read.php?262,184527,184527#msg-184527 Sun, 10 May 2026 10:26:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,184527,185456#msg-185456 https://reprap.org/forum/read.php?262,184527,185456#msg-185456
I'm using good 3mm filament. is has a listed variance of "2.81-2.89mm". I have my Slic3r 9.8 set to 2.87 for a smooth top finish.

However, last time I printed on the Blue spool, I had signs of over fill in areas where solid fill was necessary, (Usually print with 20-25% fill), So, I'll have to bump the setting up until it comes out right.

Some Bad filament can actually get larger than 3mm. I had some I had to run at 3.2 or about for good prints.

I find that averaging the measurements just gets me in the ballpark. (Latest Slic3r seems to need higher values...)
So, I usually run some test-prints and adjust the values from the results.

Some Filament will even drift over the length of the roll.]]> Komb' Printing Sun, 17 Feb 2013 16:27:06 -0500 https://reprap.org/forum/read.php?262,184527,184843#msg-184843 https://reprap.org/forum/read.php?262,184527,184843#msg-184843
I have a set of electronic claipers that indicates 1/100mm. You can enter it in slicer to tenths. The usual advice is to take measurements at several places on the filament and take the average. However, with one brand of filament I discovered that it wasn't actually round - so measure, rotate the calipers and measure again the diametre at 90 degs to the first measurement and average. If your filament is wider than slicer thinks it is it will extrude too much plastic.

Even with a good consistent filament and measured acuratly the extruder still can drag through the filament. The upper layers are still going to have expanded. I was printing a part last night and after about 30 layers the extruder stalled as it ran into the part. (the part was very well stuck down.) The Y axis was then out a few steps. I resliced it with lift activated (1mm) and on the next attempt I got a good part. (after a 5hr print)]]> TerryKidd Printing Fri, 15 Feb 2013 03:16:25 -0500 https://reprap.org/forum/read.php?262,184527,184785#msg-184785 https://reprap.org/forum/read.php?262,184527,184785#msg-184785
Make sure you bed is leveled and you can hardly move two sheets of paper between the extruder and the bed.]]> fsamir Printing Thu, 14 Feb 2013 20:47:47 -0500 https://reprap.org/forum/read.php?262,184527,184679#msg-184679 https://reprap.org/forum/read.php?262,184527,184679#msg-184679
I'll take a photo of my test cube tonight and post it. I did a Z calibration with a sheet of paper yesterday and I did verify that I'm printing 3mm filament.


Thanks again!]]> rteslow Printing Thu, 14 Feb 2013 14:14:24 -0500 https://reprap.org/forum/read.php?262,184527,184677#msg-184677 https://reprap.org/forum/read.php?262,184527,184677#msg-184677
If you mean the nozzle is dragging through the print when doing fill, it may be that the Extruder isn't calibrated right or your filament diameter isn't set right in Slic3r.

How dose it do on the 20mm solid cube test?]]> Komb' Printing Thu, 14 Feb 2013 14:10:42 -0500 https://reprap.org/forum/read.php?262,184527,184606#msg-184606 https://reprap.org/forum/read.php?262,184527,184606#msg-184606
