hi all when i print a plus (+), line is not going straight on X axis. i checked G code. there is no mistake in there. there is 2 or 3 mm mistake up line according to down line. i know i can't explain the problem well. but it is clear on picture. i,m using RAMPS 1.4. i thing problem in sprinter firmware. beacuse i checked belt, motor current, pulley. i'm using this "float axis_steps_per_unit[] = {91.4286, 91.4286, 4000, 910};" but circles like egg. square is not square. where is mistake? thanks for advice. https://reprap.org/forum/read.php?214,184125,184125#msg-184125 Fri, 04 Sep 2026 16:33:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?214,184125,184575#msg-184575 https://reprap.org/forum/read.php?214,184125,184575#msg-184575 nophead Huxley Thu, 14 Feb 2013 06:06:14 -0500 https://reprap.org/forum/read.php?214,184125,184547#msg-184547 https://reprap.org/forum/read.php?214,184125,184547#msg-184547 nikbjo Huxley Thu, 14 Feb 2013 04:11:51 -0500 https://reprap.org/forum/read.php?214,184125,184125#msg-184125 https://reprap.org/forum/read.php?214,184125,184125#msg-184125
