Only probe where the part will be printed

@Proschi78
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.

@danym21 Error: in GCode file line 182 column 7: M221: expected number after 'S'
Extruder pressure advance: 0.065, 0.000
Error: in file macro line 8 column 8: M557: unknown value 'first_layer_print_min^'

can you give me your whole start code ?
and mesh.g ?

jetzt gehts
now it works

@Proschi78

Proschi3D

@danym21 Do you also have start codes for other slicers?

danym21

@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 ?

danym21

@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

Proschi3D

@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 z

M558 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

danym21

@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?
