Hi, I have a marlin based 3d printer. My printer use the coreXY system. I tried to print this model using ABS and i have this problem: - The first layers are ok but in middle the print are deformed. I'm using this temperature configuration: - BED 110° - NOZZLE 225° - FAN OFF Any ideas?

do you have a hood or cover for your printer?

close in the printer so the air around the print is kept warm and no drafts, boost your extrude temp a little say 245c

A hood for ABS printing is a must.... Or a really really hot room!!! :)

check and see if your fan comes on at those layers....

I doubt your over extruding, or it would show at the lower levels too...]]> JustSumGuy Printing Mon, 16 Oct 2017 17:07:56 -0400 https://reprap.org/forum/read.php?262,785656,790021#msg-790021 https://reprap.org/forum/read.php?262,785656,790021#msg-790021
Temperature might also be an issue. I would say it is a little too cold, but I don't have enough information to make a better educated guess.]]> jcabrer Printing Wed, 27 Sep 2017 13:28:46 -0400 https://reprap.org/forum/read.php?262,785656,787833#msg-787833 https://reprap.org/forum/read.php?262,785656,787833#msg-787833 or/and the infill and/or you have to specify height and then width of the extrusion.

but pictures and more details at mentioned above would be very helpfull.]]> Gaou Printing Tue, 12 Sep 2017 01:56:17 -0400 https://reprap.org/forum/read.php?262,785656,787175#msg-787175 https://reprap.org/forum/read.php?262,785656,787175#msg-787175 Inhumierer Printing Fri, 08 Sep 2017 03:52:31 -0400 https://reprap.org/forum/read.php?262,785656,785693#msg-785693 https://reprap.org/forum/read.php?262,785656,785693#msg-785693 Are you printing just one at a time?
That second picture from the top almost looks like underextrusion but its hard to tell with the glare and all.

ABS likes to go slower and have loads of time to solidify. I print mostly all ABS and I print at no faster than 40mm/sec and print at about 240c]]> Floyd Printing Wed, 30 Aug 2017 14:07:02 -0400 https://reprap.org/forum/read.php?262,785656,785672#msg-785672 https://reprap.org/forum/read.php?262,785656,785672#msg-785672 DapDeveloper Printing Wed, 30 Aug 2017 11:24:56 -0400 https://reprap.org/forum/read.php?262,785656,785669#msg-785669 https://reprap.org/forum/read.php?262,785656,785669#msg-785669 the_digital_dentist Printing Wed, 30 Aug 2017 11:10:59 -0400 https://reprap.org/forum/read.php?262,785656,785666#msg-785666 https://reprap.org/forum/read.php?262,785656,785666#msg-785666 DapDeveloper Printing Wed, 30 Aug 2017 10:54:23 -0400 https://reprap.org/forum/read.php?262,785656,785663#msg-785663 https://reprap.org/forum/read.php?262,785656,785663#msg-785663 The problem is that i have printed 4 of this model and are equal.]]> DapDeveloper Printing Wed, 30 Aug 2017 10:50:45 -0400 https://reprap.org/forum/read.php?262,785656,785662#msg-785662 https://reprap.org/forum/read.php?262,785656,785662#msg-785662 Have you calibrated your extruder?]]> Floyd Printing Wed, 30 Aug 2017 10:42:58 -0400 https://reprap.org/forum/read.php?262,785656,785656#msg-785656 https://reprap.org/forum/read.php?262,785656,785656#msg-785656 I have a marlin based 3d printer.
