Need some help My X stepper motor is very noisy and starts skipping steps after about 5-10 layers The noise it makes is a grinding growling noise and not the normal squealing musical noise of a stepper. I have tried adjusting the driver from low to high. Skipping and noise gets louder the higher I go. 3 different drivers 3 different steppers 2 different ramps boards Using Repetier Firmware (latest Version) Adjusted stepper driver, Jerk, Travel Acceleration, Print Acceleration without change Using a Chimera hotend with Nimble Extruder. All other stepers work fine and as expected. Able to print a 10x10mm square box and a 20x20 hollow box without issue Any other print causes the skipping steps. X carriage freely moves by hand with no hangups. Belt is tight but not to tight The only thing that hasnt been swapped out at this time is the Arduino Mega. Not sure this could cause the issue I am having https://reprap.org/forum/read.php?406,805763,805763#msg-805763 Tue, 10 Mar 2026 06:02:13 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,805763,806363#msg-806363 https://reprap.org/forum/read.php?406,805763,806363#msg-806363 Cletus81 Prusa i3 and variants Fri, 19 Jan 2018 20:11:17 -0500 https://reprap.org/forum/read.php?406,805763,806023#msg-806023 https://reprap.org/forum/read.php?406,805763,806023#msg-806023 Roger123D Prusa i3 and variants Wed, 17 Jan 2018 21:24:08 -0500 https://reprap.org/forum/read.php?406,805763,805763#msg-805763 https://reprap.org/forum/read.php?406,805763,805763#msg-805763 My X stepper motor is very noisy and starts skipping steps after about 5-10 layers
