I have been trying to print a new x carriage but the bearing holders keep breaking when I try to remove the finished part. It is this part: [www.thingiverse.com] Is there something I need to calibrate to keep layers from being brittle? Anything I print that is taller than 2cm becomes brittle. https://reprap.org/forum/read.php?1,185735,185735#msg-185735 Tue, 14 Jul 2026 06:02:21 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,185735,186477#msg-186477 https://reprap.org/forum/read.php?1,185735,186477#msg-186477
The layers need to be slightly squished into each other to make a good bond.

At 0.5mm on a 0.5mm nozzle they are just laying on each other. very little surface contact to bond with.]]> Komb' General Thu, 21 Feb 2013 09:36:05 -0500 https://reprap.org/forum/read.php?1,185735,186095#msg-186095 https://reprap.org/forum/read.php?1,185735,186095#msg-186095 waitaki General Wed, 20 Feb 2013 01:41:26 -0500 https://reprap.org/forum/read.php?1,185735,186062#msg-186062 https://reprap.org/forum/read.php?1,185735,186062#msg-186062 CivilEITprint General Tue, 19 Feb 2013 19:14:12 -0500 https://reprap.org/forum/read.php?1,185735,185938#msg-185938 https://reprap.org/forum/read.php?1,185735,185938#msg-185938
But in the OPs case, as few details as we have, he says they are breaking as they get taller... This leads me to believe he is using an improper steps/mm (too high?) Which is causing the layers to get progressively further apart in height as he prints.]]> xclusive585 General Tue, 19 Feb 2013 13:08:56 -0500 https://reprap.org/forum/read.php?1,185735,185935#msg-185935 https://reprap.org/forum/read.php?1,185735,185935#msg-185935
Wrong layer height. (trying to print .4 layers with a .35 head...)

printing too cold. I've had beautiful prints that would break easily with a little pressure. Bumped the temp up 5deg. and the same print came out Solid!

Also I hear too much cooling (fan) can cause PLA to not bond properly also.]]> Komb' General Tue, 19 Feb 2013 13:01:21 -0500 https://reprap.org/forum/read.php?1,185735,185857#msg-185857 https://reprap.org/forum/read.php?1,185735,185857#msg-185857 jamesdanielv General Tue, 19 Feb 2013 06:58:10 -0500 https://reprap.org/forum/read.php?1,185735,185849#msg-185849 https://reprap.org/forum/read.php?1,185735,185849#msg-185849 MPower General Tue, 19 Feb 2013 05:55:24 -0500 https://reprap.org/forum/read.php?1,185735,185751#msg-185751 https://reprap.org/forum/read.php?1,185735,185751#msg-185751
fwiw, in general, it's nice to know the material you're printing with (ABS, PLA, etc.) the hot-end temperature, layer thickness, etc. in order to clarify and isolate common problem sources.]]> xiando General Mon, 18 Feb 2013 18:23:55 -0500 https://reprap.org/forum/read.php?1,185735,185749#msg-185749 https://reprap.org/forum/read.php?1,185735,185749#msg-185749 What settings?
Can you show a picture of the issue?]]> Polygonhell General Mon, 18 Feb 2013 18:18:43 -0500 https://reprap.org/forum/read.php?1,185735,185735#msg-185735 https://reprap.org/forum/read.php?1,185735,185735#msg-185735 www.thingiverse.com]
