Hello, I have problems with electronics, my model is an i3, and use a ramps 1.4, the problem is that the engines only me move in one direction, for example the warm bed only moves backwards and never forwards, I know this because I use the manual control featuring repetier - host. Moreover I have used the marlin to load data from the arduino board. I've been around but can not find the solution, it is probably silly. I hope answers. https://reprap.org/forum/read.php?1,309917,309917#msg-309917 Thu, 12 Mar 2026 09:36:11 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,309917,310124#msg-310124 https://reprap.org/forum/read.php?1,309917,310124#msg-310124 cat.farmer General Wed, 12 Feb 2014 15:41:16 -0500 https://reprap.org/forum/read.php?1,309917,310111#msg-310111 https://reprap.org/forum/read.php?1,309917,310111#msg-310111
When we plug the printer for the first time, engines moved in both directions of automatic way, the hot bed and heated extruder also heated.

When we loaded the files in the Arduino Marlin, the engines stopped working automatically. Now just move manually in one direction. And the extruder and heated bed no.]]> chupis General Wed, 12 Feb 2014 15:20:45 -0500 https://reprap.org/forum/read.php?1,309917,309951#msg-309951 https://reprap.org/forum/read.php?1,309917,309951#msg-309951 cdru General Wed, 12 Feb 2014 10:27:41 -0500 https://reprap.org/forum/read.php?1,309917,309925#msg-309925 https://reprap.org/forum/read.php?1,309917,309925#msg-309925 chupis General Wed, 12 Feb 2014 09:28:34 -0500 https://reprap.org/forum/read.php?1,309917,309919#msg-309919 https://reprap.org/forum/read.php?1,309917,309919#msg-309919 cat.farmer General Wed, 12 Feb 2014 09:21:16 -0500 https://reprap.org/forum/read.php?1,309917,309917#msg-309917 https://reprap.org/forum/read.php?1,309917,309917#msg-309917 chupis General Wed, 12 Feb 2014 09:19:06 -0500
