Hi guys. Hopefully you will be able to help me with a little problem Ive run into. Im in the process of building a RepRap Prusa Mendel iteration 3. The electronics is a RAMPS 1.4 Shield on an Arduino board. I was testing my electronics today and it seems my Y-axis does not function properly, so Ive been troubleshooting. When Y-axis motor is connected to Y-axis stepper controller, it functions sporadically. The motor vibrates and wants to move, but doesnt or only moves in jolts/jitters. When Y-axis motor is connected to X-axis stepper controller, it functions perfectly moving smoothly. So it seems the problem is with the Y-axis stepper controller. However, the fact that the motor does vibrate and moves in jolts tells me that the controller is not burnt. Do you have any suggestions before i tear apart my electronics to do a resoldering of the Y-axis controller? I have checked the current already to the stepper controller and that does not seem to be an issue. https://reprap.org/forum/read.php?219,204126,204126#msg-204126 Tue, 15 Sep 2026 20:54:43 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,204126,205581#msg-205581 https://reprap.org/forum/read.php?219,204126,205581#msg-205581 JesperG RAMPS Electronics Sun, 05 May 2013 07:20:47 -0400 https://reprap.org/forum/read.php?219,204126,205529#msg-205529 https://reprap.org/forum/read.php?219,204126,205529#msg-205529 f3rDz RAMPS Electronics Sun, 05 May 2013 00:55:05 -0400 https://reprap.org/forum/read.php?219,204126,204294#msg-204294 https://reprap.org/forum/read.php?219,204126,204294#msg-204294 JesperG RAMPS Electronics Wed, 01 May 2013 02:41:20 -0400 https://reprap.org/forum/read.php?219,204126,204218#msg-204218 https://reprap.org/forum/read.php?219,204126,204218#msg-204218
edit. have you checked the current the driver is set to? to high, or too low can cause similar issues that you are experiencing]]> lazzymonk RAMPS Electronics Tue, 30 Apr 2013 17:32:25 -0400 https://reprap.org/forum/read.php?219,204126,204126#msg-204126 https://reprap.org/forum/read.php?219,204126,204126#msg-204126
