I’ve been lately trying to do a test print of the marvin model on my Printrbot Simple metal (newest version).
I’m using Cura as a slicer, printing with 100 microns layer height, a fill density of 25%, print speed of 50 mm/s and a printing temperature of 205 °C.
My material is regular black PLA. I’ve always had problems where my print wouldn’t stick well enough to the print bed, and the last layers would be scratched up by the nozzle. Therefor I turned the flow rate down to 90%.
My Marvin here turned out good, but it looks like it started to warp on one side of the print after it had finished the feet. Overall the edges of a layer sometimes peel up a bit, making the following layers look horrible.
I know that the first layer is really important and has to stick well, but no matter what I did, some edges always seem to warp up and create these scratches/marks at the sides. I guess it has something to do with warping, but the material is PLA, and there is no real fix for that. Though I have an assumption that my fan shroud is not cooling the layer correctly.
The left side looks normal.
The right side on the other hand has a roughed up surface.
These problems have been bothering me alot and I just want to make clear and good looking prints. Maybe some of you have a similar problem or maybe even have a solution for it?
