Need help with initial layer


Recommended Posts

Posted · Need help with initial layer

Hello, 
 

I am new to this forum and I need some help.
The issue I'm having is that when my printer makes the first layer in puts this ugly line across the layer. (picture included). I need a clean first layer as the visual aspects is important in this case.
It starts by doing the walls first and then while it is moving to the filling it looks like it is still extruding while and leaving a line.
I tried adjusting the z hop and retract values but so far I haven't managed to make it work. I also changed the fill pattern and it still does it. 
Does somebody know how I can fix this?


Thank you in advance.

    There are going to be some lines because you have the bottom pattern set to "concentric".  The lines will be where the nozzle shifts to the next loop.

    That heavy line going from the middle area to the top looks more like there was an extrusion at the start when the nozzle traveled from the outer wall to start the concentric skin.  If there was no retraction there then you didn't get a Z-hop either.  Check your Travel settings for "Retraction Minimum Travel" and "Max Comb Distance with No Retract".  For that print both should be low numbers like around 3 to 5.

    You might also try "Avoid Printed Parts When Traveling" and see if it helps.
