Cura causing filament to extrude before the hotend touches the build plate?

Recommended Posts

Im not sure why, but I am having a problem with the Cura software and my 3d printer. How do I know this is a problem with the Cura software? I noticed it was Cura and not my printer when I tried using a different 3d printing software called MatterControl from MatterHackers.

The problem I am noticing on Cura is that filament starts to extrude before the hotend has touched the build plate causing it to curl and then tangle with filament that is being printed for the first layer. Any help would be great!!!

Hello !

I am only using cura since I start printing stuff and on all the different version I tried, Cura always start extruding filament before printing. I don't think this is actualy a bug.

Normaly, it extrude on the front left corner of the printer and after few centimeters extruded, it start printing. If your nozzle is very clean, the filament extruded should go smoothly on the build plate and form a kind of small circle.

If you start printing the object just after that (without skirt or brim) the filament can sometimes srcew a part of the first layer. It happens to me on very big first layer, it was almost as big as the buildplate of my um2 extended.

Here 2 pictures about what i said :

first_layer.thumb.jpg.8b9b997908fbefe94ddc60ba575cc6d4.jpg

On those two pictures you can see the initial extrusion, which is normal and on the second, the begining of the first layer of ultimaker robot gcode (with a skirt). This is actually some red pla. What material are you using ?

Normaly it is not a problem.

If you talk about somethink different than that, you should check you gcode or show it to someone who understand it well.

Good luck, hope it helps
