Answered Printing in air

It happened every time. I am using Robo 3D R1.

G code:
G28 ; home all axes
G1 Z5 F5000 ; lift nozzle
M109 S[temperature] ; set the extruder temp and wait
G28 Z0 ; Home Z again in case there was filament on nozzle
M565 Z0
G29 ; probe the bed

Z Offset is 0.9mm

 

Your filament jammed, run an oiler with PLA

 

or if the extruder stops turning, your temp got too low. "stopped to prevent cold extrusion". or something like that.
If its turning and nothing is coming out... obviously clogged or jammed. The tiniest kink will stop it from getting into the hotend.

Also, if you're using the stock filament feed setup, or similar. If the filament has to pull too hard, it can strip and not extrude.

 

Thanks Mike I will try to make an oiler first.

 

Hi, Ben thanks for the reply.
The extruder was 210° and the heatbed was 50° while it's printing. Anyway, I will try to make an oiler first then see how it's going.
