<![CDATA[SoliForum - 3D Printing Community — Weird mid-layer extruder shift?]]> https://www.soliforum.com/topic/6466/weird-midlayer-extruder-shift/ Tue, 27 May 2014 15:24:51 +0000 PunBB <![CDATA[Re: Weird mid-layer extruder shift?]]> https://www.soliforum.com/post/57082/#p57082 If you have ensured that the generated G-code isn't showing that path then you might adjust the VREF's.  I put it that way because this just doesn't look like normal stepper skipping to me.  Sometimes it is difficult to tell from a picture with out putting it into context (.stl) so we know what it is supposed to look like.

To verify this is the problem, just get a desktop fan and put it behind the printer pointing to the electronics. 

Does this solve the problem?  Then print one of the many fan holders here and on Thingiverse, for a permanent fan installation.
