X-Axis Sticks, Then Skips Ahead When I'm printing with my Prusa Mendel, the print head will be moving along its rails then stick in place for a second or two and then begin moving again, ruining the print by offsetting all layers printed after the stick, resulting in a bifurcated piece. I don't know the cause of the problem. My thoughts have been either that the rails are bent, there is an electronics malfunction, or there is a problem with my firmware. I'm currently using Gen6 electronics with Sprinter firmware. Any advice would be appreciated. https://reprap.org/forum/read.php?151,245541,245541#msg-245541 Tue, 15 Sep 2026 11:39:44 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,245541,297080#msg-297080 Re: X-Axis Sticks, Then Skips Ahead https://reprap.org/forum/read.php?151,245541,297080#msg-297080 MaFraL General Mendel Topics Sat, 18 Jan 2014 11:33:25 -0500 https://reprap.org/forum/read.php?151,245541,296851#msg-296851 Re: X-Axis Sticks, Then Skips Ahead https://reprap.org/forum/read.php?151,245541,296851#msg-296851 First I checked the belt wasn't rubbing against its guides on both sides.
Then I loosened the belt to the most it could be loosened to.
Then I drilled holes in the extruder to mount the X axis on bearings using tie-down straps.
Then I cleaned the rods with circuit-cleaner. Then I lubed the rods with lithium grease (the person and JCar said he uses Lanolin).
Then I tried adusting the setting on the driver board.
Then I tried using 3 bearings instead of 4.
Then I tried using Marlin instead of Sprinter.
After all that I noticed that the hex screw holding the gear onto the motor shaft could do with a 1/4 turn extra tightening (be careful not to strip your thread, it's not a very strong thread).
Problem solved.]]> Sandstorm General Mendel Topics Sat, 18 Jan 2014 02:53:49 -0500 https://reprap.org/forum/read.php?151,245541,245554#msg-245554 Re: X-Axis Sticks, Then Skips Ahead https://reprap.org/forum/read.php?151,245541,245554#msg-245554 MaFraL General Mendel Topics Sun, 15 Sep 2013 13:45:58 -0400 https://reprap.org/forum/read.php?151,245541,245550#msg-245550 Re: X-Axis Sticks, Then Skips Ahead https://reprap.org/forum/read.php?151,245541,245550#msg-245550 stefanjess91 General Mendel Topics Sun, 15 Sep 2013 13:28:03 -0400 https://reprap.org/forum/read.php?151,245541,245541#msg-245541 X-Axis Sticks, Then Skips Ahead https://reprap.org/forum/read.php?151,245541,245541#msg-245541 MaFraL General Mendel Topics Sun, 15 Sep 2013 12:33:15 -0400
