No more priming in custom g code in Slic3r?

This is the start g code in Slic3r:

M115 U3.0.12 ; tell printer latest fw version
; Start G-Code sequence START
T[initial_tool]
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
G28 W
G80
G92 E0.0
M203 E100
M92 E140
G92 E0.0
M900 K200

There is no code to prime the nozzle it seems?

The priming is done by the wipe tower generator internally in all cases now as long as the wipe tower is enabled in the print settings. In case there is no wipe tower, the internal wipe tower generator extrudes the single material extrusion line at the edge of the bed.

Yeah but the single extrusion along the edge does not properly prime a freshly loaded filament. My workaround is to go to settings - move axis - extruder and turn the knob exactly two turns or about 40mm to properly prime the system on a single filament run. I guess I could add the wipe tower to single filament prints or add gcode to do the priming for me?

Hmmm, I just looked into my two options and neither will work unless I figure out how to add a wipe area even in single color prints. Anyone know how to do that?

Frankly, there must be some issue at your side.

What slic3r version are you using? Where did you get the Slic3r profiles from? Which Slic3r profile are you printing with? Is your printer a single material or a multi-material one?

Thanks, Vojtech

I confirm that it primes automatically
