Bottom layers over extruding/squashed


Recommended Posts

Posted (edited) · Bottom layers over extruding/squashed

Hi,

 

I've been using my 3D printer for about a year now and recently I noticed the bottom layers of the print were coming out squashed. I've tried countless things to fix this problem (changing flow rate re-levelling bed changing heat of bed etc) but it is still coming out the same. Anyone know what to do?

 

Thanks.

    What are your initial layer height and initial layer width set to relative to the primary layer height? If the initial layer height is too low or the initial layer width is too wide (or both), it will squish the first layer.

    You can also compensate the bottom layer with "Initial Horizontal Expansion". Set it to -0.3 or something like that.
