Prusa X Motor End Issue I think the X Motor End needs to be modified to allow the pulley to be more in line with the idler's 608 bearing. Even if the pulley was backwards and flush against the motor, only 3mm of belt would be able to fit on the 608 bearing. Here's a picture of what I'm talking about: 7NIff.jpg mod_embed_images_loadimage('08b3ca6173c9477b8bded435950f0738', '/forum/thumbcache/b03/54b/339/db3/dfc/87a/d5e/31f/d63/14d/d0_800x400.png', 'http://i.imgur.com/7NIff.jpg', 'https://reprap.org/forum/addon.php?151,module=embed_images,check_scaling=1,url=http%3A%2F%2Fi.imgur.com%2F7NIff.jpg', '', 125699, 800, 400, 'Loading image ...', false); Here's my temporary fix (I added some washers between the motor and x end): ze3hC.jpg mod_embed_images_loadimage('e48363551a29109c06ec9c003ed53b34', '/forum/thumbcache/21c/1b7/fb2/e37/c52/205/b11/100/3f7/152/30_800x400.jpg', 'http://i.imgur.com/ze3hC.jpg', 'https://reprap.org/forum/addon.php?151,module=embed_images,check_scaling=1,url=http%3A%2F%2Fi.imgur.com%2Fze3hC.jpg', '', 125699, 800, 400, 'Loading image ...', false); https://reprap.org/forum/read.php?151,125699,125699#msg-125699 Sun, 19 Jul 2026 18:26:37 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,125699,128461#msg-128461 Re: Prusa X Motor End Issue https://reprap.org/forum/read.php?151,125699,128461#msg-128461

I had the same problem, but fixed it by adding just one washer in the bolt closest to the X carriage. That tilted the motor a tiny bit and made the belt run correctly without rubbing against anything. It's still a hack, though. Would be nicer to have everything line up correctly.]]> ttsalo General Mendel Topics Mon, 26 Mar 2012 08:06:07 -0400 https://reprap.org/forum/read.php?151,125699,125850#msg-125850 Re: Prusa X Motor End Issue https://reprap.org/forum/read.php?151,125699,125850#msg-125850

Here's a picture of how it lines up with the x-carriage. The wall that the bolt sits against on the x-idler could move toward the rod ~7mm before the belt would be on top of the x-carriage's bolt hole. However, the motor can only move away from the rods ~4mm before the same thing happens (that's how much spacing you need with your washers - 4mm, 8 m3 washers, or 5 m4 washers).

If we're going to change the .scad files, moving the motor out and idler wall in would give us the most room.
