@Adam_Steinmark
cura (as slicer) is stupid (to not offend programmers that make it) because it put stupid patterns for infill, it make the printer doing movements for nothing while printing; i even made a stl where it slice and give an object with onily stupid infill 
i got same problem. i tried to add my own G Code to make the extruder pushing out the filament a little bit before printing the model.
that’s the code:
"; Default start code
G28 ; Home extruder
G1 Z15 F{Z_TRAVEL_SPEED}
;M106 ; Turn on fan
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
{IF_BED}M190 S{BED}
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{TEMP0}
;G0 Z0.20
G1 E5
G92 E0 ; Reset extruder position"
it works much better, but still has problem .
so …I changed config of “skirt line cout” to be 2. now it’s working well.
@christophe_malvasio maybe it was an Stl where when sliced the perimeters could not be determined. Meshmixer inspector will show stl files like that.
The fix is to make them solid as 1 object. You can then hollow it back out if you want.
@Nathan_Walkner what type of printer do you have? I’ve figured out a lot of stuff with Cura. It is very quick. I’ve had no problems connecting to a printer. Ive tried pronterface? Slic3r. I now use OctoPrint. I usually run cura elsewhere and upload the gcode to octoprint instead of octoprint calling cura.
@Lee_JinHao the problem with not having it printing correctly right away is that PLA fibers/hairs can be left on the plate which can end up on the bottom surface of a print.
I print stuff for Other people that can be very particular about quality.
My best solution is to have a line stl at the front of the bed. It always gets printed first.
I also clean off the nozzle and then push filament into the nozzle just before it goes to home. That makes the filament stick to home and excess filament is pulled out as it goes to the first object. Identical results every time!
@Pablo_Herrera hey.
If I put an sd card into my computer, cura will save the gcode to the card when i select print. (When an option to detect sd card is on). If i wish to print straight to printer, i keep sd card out of computer (and printer although this isnt necessary for me. Marlin firmware.)
I would try and select slicers based upon improvements for a print, not necessarily upon how attentive I am on any day.
Slic3r had many more options than I comprehended when I looked at it. I now understand most parameters in my config file and how each affects the printer.
I understand a lot of what Cura does and why. Soon I will try slic3r again, but I will be testing really detail nits to learn how to use each slicer to its utmost (not slam cura because it doesn’t do what I want.) I am open to better ways.
got it. .I will follow your solution. thank you!
