Curaengine

Hi there can someone tell me why when i slice with curaengine that there is no nozzle prime before printing starts as i have a problem getting the print to start
proper it is on the second or third pass before there is filament extruding properly.
other than that it works well

Because you don’t have a nozzle prime command in your cura start gcode.

hi i am using
Repetier-Host Windows 1.0.6
windows 8.1
my printer k8200
I use the cura slicer on-board the Repetier-Host Windows 1.0.6
and check the code for a primer and i can’t see one.

Here is the Start g-code of the Vertex. Compare it with yours.

G28 ; Home extruder G1 Z5 F{Z_TRAVEL_SPEED} G1 Z0 F{Z_TRAVEL_SPEED} G90 ; Absolute positioning M82 ; Extruder in absolute mode {IF_BED}M190 S{BED} M106 S80 ; Turn on fan ; Activate all used extruder {IF_EXT0}M104 T0 S{TEMP0} {IF_EXT1}M104 T1 S{TEMP1} G92 E0 ; Reset extruder position ; Wait for all used extruders to reach temperature {IF_EXT0}M109 T0 S{TEMP0} {IF_EXT1}M109 T1 S{TEMP1} {IF_EXT0}T0 {IF_EXT1}T1 M83 G1 E10 F100 M82 G92 E0 ; Reset extruder position M117 La Vertex imprime G1 F1000 Z5
G1 E10 F100 is the prime code.

Don’t forget that cold extrude prevention can prevent a prime depending on sequencing and lack of a manual pre-heat.

G1 E10 F100 is the prime code.[/quote]
I have the same problem…
So can we just copy that line or will be better to copy all the code for the start?
