Only probe where the part will be printed

@Proschi78
I'm unsure where the code you have posted is located.
Please try the following in your Prusa Start GCode.
Don't call any other macros from Prusa!M118 S"Begin slicer start g code" ;M104 S0 R0 P{current_extruder} ;Dummy Set temps to zero to stop slicer adding them T{current_extruder} ; select tool used on first layer M703 ; load config file for [filament_type] G90 ; Switch to using Absolute Coordinates M82 ; set extruder to absolute mode M568 P{current_extruder} R{"{heat.coldExtrudeTemperature+5}"} S{first_layer_temperature[current_extruder]} A1 ; (set extruder to stanby to soften any protruding filament before probing ) M106 P{current_extruder} S0 ;Start with fan off M118 S"Heating Bed" G4 S1 M140 S{first_layer_bed_temperature[current_extruder]} R{bed_temperature[0]-20}; Set fast bed temp & standby - Standby is 20 degrees less than normal.

Hi, I use SuperSlicer, but I think in prusa Slicer it should also work.
in my startcode I added this line:M557 X{first_layer_print_min[0]}:{first_layer_print_max[0]} Y{first_layer_print_min[1]}:{first_layer_print_max[1]}
maybe this will help you too.

jetzt gehts
now it works -
@Proschi78
-
@danym21 Do you also have start codes for other slicers?
-
@Proschi78
no, sorry
but on S3d maybe have a look to this variables:
I do not know what is in, but you can test with a smal object and check then the gcode file[build_size_x] [build_size_y] [build_size_z] .... [next_position_x] [next_position_y] [next_position_z]
they are mentioned here:

@danym21 thanks I'll test that tomorrow

what can I do with this start code so that it is probing in mesh like A5 in normal mesh?
Best off five ? -
@Proschi78 said in Only probe where the part will be printed:
ke A5 in no
the A5 needs to be in the config.g where you configure the probe type
look for M558
https://docs.duet3d.com/User_manual/Reference/Gcodes#m558-set-z-probe-type -
@danym21
Hello,
I know that and I also have it in the config.g
but if I start a print and it only creates the mesh where the printed part is, then it only runs once in zM558 P1 C"io3.in" H5 A5 S0.009 F150 T6000 ; set Z probe type to unmodulated and the dive height + speeds G31 P500 X0 Y0 Z1.730; set Z probe trigger value, offset and trigger height M557 X30:330 Y-3:210 P9
-
@Proschi78
mhm, this makes no sense for me, do you have a M558 on some other positions? like in the the bed.g or config-override.g?I will test this when I have time for, I normaly use only one probe per point.

Just want to share the solution I made for this a couple of months ago (posted here)
as well.It works with PrusaSlicer/SuperSlicer, Cura and Ideamaker. Instructions are included as well.

Has anyone managed to do it with simplify v5?
