Problems summary :
- infill (25%) sometime not starting after perimeter (probably solved)
- curling (normal with ABS ?)
- layer not sticking well
- top infill not filling enough
All the print are done at 230C in a room at 21-22 Celcius and 40% humidity.
Greg Wade Reload Extruder. No problem with adhesion on heatbed (at 120C)
E_Step calibrated without hotend with this filament.
The average filament diameter is 2.8 and this is what is use in slic3r.
I’m slicing with slic3r 0.9.8 (I have not switched jet to 0.9.9). Couldn’t attach the config file (3 files max) so get it here.
Edit : For almost all purpose the printer is a Prusa Mendel i2
Edit 2 : With a Budashnozzle 1.2, 0.35mm
Problem 1 and 2 noticed with the 20mm box.
Sometime (not every layer) when stating to make the 25% infill, the infill would not start immediatly and coming out dotty over the last infill. Jebba suggested tweeking the retraction, which I still have to test to my liking. The red circling in the picture is what I think the result of a bad infill under the top layer.
The side of the box are not straight, I read that it may be link to ABS cooling to fast and infill cooling pulling on perimeter. I make sens, I’m thinking of boxing my printer so it will keep a higher temperature around. Would it help ?
Problem 3 and 4 where notice while printing a self design model.
You can see in the picture where the arrow points some layer clearly where not sticking well. I clued them with homemade ABS cement. Other layer not pointed with arrows are not sticking well. What could I do ? rising print temp ? would boxing the printer help ?
You can see in the picture that the top of this fence post is not 100% filled. The other post is better filled, but it could be better. I haven’t configure extrusion multiplier could it help ?
Thank you in advance.
