Hello, I have been here before because my motors would only vibrate, the problem was that I had my motors connected wrong. Since then, I have checked the continuity of my steppers and rewired them. Now, my motors turn smoothly for a few seconds, but then stop and begin vibrating. Plaese help, I'm tired of my motors not turning correctly:( By the way, I'm running marlin with RAMPS 1.4 https://reprap.org/forum/read.php?262,384644,384644#msg-384644 Fri, 04 Sep 2026 16:19:23 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,384644,384916#msg-384916 https://reprap.org/forum/read.php?262,384644,384916#msg-384916 surfacelane Printing Fri, 18 Jul 2014 11:52:35 -0400 https://reprap.org/forum/read.php?262,384644,384910#msg-384910 https://reprap.org/forum/read.php?262,384644,384910#msg-384910 surfacelane Printing Fri, 18 Jul 2014 11:46:05 -0400 https://reprap.org/forum/read.php?262,384644,384740#msg-384740 https://reprap.org/forum/read.php?262,384644,384740#msg-384740 reprap.org]]]> Traumflug Printing Fri, 18 Jul 2014 05:20:22 -0400 https://reprap.org/forum/read.php?262,384644,384651#msg-384651 https://reprap.org/forum/read.php?262,384644,384651#msg-384651

Motors that run near their rated torque will not last as long as those that do not. Motors should be chosen so that they will run at 40-60% of their torque rating. [web.archive.org]
High torque stepper motors need to run at higher voltages in order for the motor to reach its full potential. Increasing the voltage supplied to a motor increases the rate at which current rises in the windings of the motor. [web.archive.org]
