My x axis moves double the distance I tell it to move, the y axis goes the correct amount. What am I doing wrong? I'm assuming I messed up the config file so I've attached it. This is on my I3 Omega, (I3XL) which is a long version of an I3X Anyone? https://reprap.org/forum/read.php?1,320410,320410#msg-320410 Thu, 16 Jul 2026 15:36:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,320410,320889#msg-320889 https://reprap.org/forum/read.php?1,320410,320889#msg-320889 piercet General Thu, 06 Mar 2014 16:49:58 -0500 https://reprap.org/forum/read.php?1,320410,320459#msg-320459 https://reprap.org/forum/read.php?1,320410,320459#msg-320459

If that doesn't fix it, I'll swap the Y axis and the x axis and see if the problem moves to the y axis.

It is exactly double though, I measured after telling it to go 1 cm, and it went 2.]]> cfy7 General Wed, 05 Mar 2014 20:50:22 -0500 https://reprap.org/forum/read.php?1,320410,320415#msg-320415 https://reprap.org/forum/read.php?1,320410,320415#msg-320415

look at ramps board,

Stepper Driver Boards
Jumpers need to be installed under each stepper driver:
jumper Yes/No step size
1 2 3
no no no full step
yes no no half step
no yes no 1/4 step
yes yes no 1/8 step
yes yes yes 1/16 step
For now the default is 1/16 micro stepping

set x/ and y to same jumper positions, the jumpers are below the pololu stepper driver chip.]]> jamesdanielv General Wed, 05 Mar 2014 20:40:32 -0500 https://reprap.org/forum/read.php?1,320410,320410#msg-320410 https://reprap.org/forum/read.php?1,320410,320410#msg-320410
