Hi I just built my first prusa i3 (Geeetech) and have ramps 1/4 with drv8825 stepstick on the ext motor wich overheats. I was told to turn the screw counter clockwise to reduce the heat... I did that and it still overheats... any help would be appreciated https://reprap.org/forum/read.php?406,717405,717405#msg-717405 Wed, 17 Jun 2026 15:31:24 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,717405,718491#msg-718491 https://reprap.org/forum/read.php?406,717405,718491#msg-718491 Roger123D Prusa i3 and variants Sun, 30 Oct 2016 23:20:57 -0400 https://reprap.org/forum/read.php?406,717405,717557#msg-717557 https://reprap.org/forum/read.php?406,717405,717557#msg-717557 cornfield Prusa i3 and variants Wed, 26 Oct 2016 16:38:21 -0400 https://reprap.org/forum/read.php?406,717405,717457#msg-717457 https://reprap.org/forum/read.php?406,717405,717457#msg-717457 around 0.5V probably works.
