I just got my RAMPS with pololu drivers, the y-axis overheats in seconds, Like count 1, 2 , OVERHEATED . The x-axis will run for considerably longer and have yet to try the z-axis (not home now ) . Is that normal? I am definetly adding a heat sink but it seems like it will not be effective enough. Is there something wrong with my Ramps? I have swapped the pololu's around and whichever driver is in the y-axis overheats, so it's not the drivers (I could be wrong) https://reprap.org/forum/read.php?1,232415,232415#msg-232415 Fri, 09 Oct 2026 00:12:04 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,232415,232649#msg-232649 https://reprap.org/forum/read.php?1,232415,232649#msg-232649 tom10122 General Sun, 04 Aug 2013 14:18:39 -0400 https://reprap.org/forum/read.php?1,232415,232603#msg-232603 https://reprap.org/forum/read.php?1,232415,232603#msg-232603 I use heat sink and I add fan over the driver.
