How does one print a solid surface. or as some would say, a smooth top surface?

Posted · How does one print a solid surface. or as some would say, a smooth top surface?

I havce done it in ABS, but with PLA it appears as cross checkered and even after sanding its cross checked. Its like it never completely fills the layer completely? id love to be able to solve this. I tried 110% flow but to no avail. seems like nothing makes any difference that i try?/

large flat and supposedly closed surface.

Funny thing is if i print small stuff it seems closed. I guess I will try again, the one above was done at 50 mm/s 0.2 and the one at the top 0.06. I have a feeling its the speed. Ill try doing a large flat object at 30mm/s but that will be a bit of a drag as it will takes aaaaages.

You could edit the gcode to adjust the speed for the layer that makes the last flatten surface and restore the speed on the next layer number. I do stuff like that with s3d postprocesing scripts because I'm lazy.

The gcode it's

M220 S- set speed factor override percentage

So M220 S80 will set the speed of all to 80% and on the next layer just do M220 S100

That most likely what has to be done as i cant see the UM making flat layers any quicker than 30/35mm/s

as my slowly printed objects are always OK, even if printed a bit quicker. Strange. Either way i dont have time to experiment with this now, so ill just have to remember this!

The bridge supports came out perfect, and the bottom shows that the layers join.
