V5.1.2 generation of unwanted g-code commands

[dadoblu_2000]

I have a problem with a command line related to the g-code created by simplify3d, I have done various tests in the configuration but the gcode is always produced in the same way, I have a modified ultimaker2 printer with a double extruder, I am noticing that after the nozzle spitting phase a command line is created related to the retraction (highlighted in blue on the attached image) here I would like to eliminate that retraction, before the brim starts printing, even if in the following lines an extrusion loading is performed at 7.35mm. Thanks for any ideas

To do what you want, paste this into the Pre Retraction Script:
{IF "[current_layer_number]==1"} ; dont retract E[retract_distance]

This has the minor side effect of disabling retraction on the first layer, but that might be sufficient in your case.

ok thanks I'll try it!

{IF "[current_layer_number]==1"} ; dont retract E[retract_distance]

I tried but it doesn't work properly, it would also be necessary to have a function that triggers the retraction, because otherwise there will be an excess of material, I explain: with the indicated function the retraction does not occur but the de-retraction function remains, therefore assuming a retraction of 5 mm by setting that function the extruder does not retract by 5 mm but de-retracts by 5 mm and this generates an excess of material that accumulates from time to time creating differences in the flow, it would be useful to have a function that inhibits the triggering and de-activation

Thanks for elaborating, in that case, this should work:
{IF "[current_layer_number]==1"} ; dont retract [retract_distance] [prime_distance]
