PrusaSlicer with Ender 3 V2 - Purge/ Prime line?

[Mark Collyer]

Hey peeps. I'm a little green to all this. I have an Ender 3 V2, which has successfully printed a few random objects, but always with some warping at the base.

I am trying to use PrusaSlicer, as I can disable the fan for the first few layers (which apparently could be my issue), but I'm not getting a Prime/ Purge line with my print (I have run the Config Wizard etc, so fairly certain I have done this reasonably correctly!).

The printer starts, then goes straight into printing the brim with no prime line, so it's making a lovely birds nest at the nozzle as the nozzle is not properly primed!

Not sure if there's any additional GCode I can add to the start GCode to print a prime line first?

I would appreciate any help!

Thanks

Here is a bog standard primer line

G92 E0 ;Reset Extruder

G1 Z2.0 F3000 ;Move Z Axis up

G1 X20 Y5.1 Z0.28 F5000.0 ;Move to start position

G1 X200.0 Y5.1 Z0.28 F1500.0 E15 ;Draw the first line

G1 X200.0 Y5.4 Z0.28 F5000.0 ;Move to side a little

G1 X20 Y5.4 Z0.28 F1500.0 E30 ;Draw the second line

G1 Z0.4 F3000; Move Z Axis Up

G1 X50 F1500; Wipe to the right

G92 E0 ;Reset Extruder

You'll put it here in PrusaSlicer
