Hi, recently I've got a problem with my x axis and I really don't know how this could be caused. The problem is this: On the first ~3mm of height my x axis moves constantly to X+ direction but the rest of the print is fine. I attached an image for better explanation, maybe someone can help me.

I just fixed the Z rods so they are both orthogonal and adjusted the length of the x axis a little bit. Then i played with the z offset because it changed during the adjustment of the Z rods and now the prints are like before, without that drift in x direction.

I'm not sure but it seems that the x axis (which is mounted on the z axis) was a little bit „braced“ or „wedged“ (I hope this are the right words for this - I'm sorry english is't my native language)

So, hanks for your help. Even if we don't know what excatly caused the fault, it works now.]]> Anonymous User Reprappers Thu, 26 Sep 2013 03:31:15 -0400 https://reprap.org/forum/read.php?4,248426,248747#msg-248747 https://reprap.org/forum/read.php?4,248426,248747#msg-248747 -------------------------------------------------------

Hm, good point. There's one double-wire that's relatively short but I don't think it's short enough to cause this.

Nice idea, will try that after fixing the Z rods.]]> Anonymous User Reprappers Thu, 26 Sep 2013 01:06:23 -0400 https://reprap.org/forum/read.php?4,248426,248703#msg-248703 https://reprap.org/forum/read.php?4,248426,248703#msg-248703

My heatbed was a little bit loose (it's spring-suspended and a nut was loose). Fixed it, print results are better, but the first 3 layers (about ~1mm of height) are still not in place.

Me too :/

If it were over the whole print it would be easy, but on so few layers? I'm honestly a little stumped.

EDIT: For the record: You were right, the Z rods are not 100% orthogonal. Will fix that tomorrow.]]> Anonymous User Reprappers Wed, 25 Sep 2013 15:49:09 -0400 https://reprap.org/forum/read.php?4,248426,248545#msg-248545 https://reprap.org/forum/read.php?4,248426,248545#msg-248545 jbernardis Reprappers Wed, 25 Sep 2013 10:43:47 -0400 https://reprap.org/forum/read.php?4,248426,248426#msg-248426 https://reprap.org/forum/read.php?4,248426,248426#msg-248426
