Printing,driving around at the beginning

Snapmaker 2.0
1

hello snappers,
im not sure if this is a prusaslicer or a common snapmaker thing.
when i start a print, my printer always drives around as shown on the screenshot, then stops after step 5, heats up to 250, extrudes a blop, moves to the next spot after step 6, then extrudes a line till the end of step 7 and then it begins with the object.
is there a way i can disable the steps 1 to 5 or if necessary all the steps?
thank you!

edit: i found that this routine is a prusaslicer thing. any idea how i can disable it?

If you go to printers → Custom G-code → Start G code section That’s where all the extra startup moves are coming from.

All you have to do is take out the commands you don’t want the printer to do at the beginning

The maintained by line web address talks about what each entry does

thank you for your answer.
im a real noob with gcode.

thats what is in the custom gcode.
what lines are the ones for driving around?
thank you very much!

edti: are the g0 the ones moving around?

Don’t feel bad so am I

I believe it’s this section

It sets the temperature of the nozzle and then runs around

M190 R{first_layer_bed_temperature[initial_extruder]}

I also think there’s also a typo in the flush routine

Instead of z1.6 it should be set at z216 so the head is farther away from the bed during purge
