@Proschi78
Where are you setting your temps?
If it's in your filament config.g then post that too.
If you don't put heater settings in PS start code, it will probably do it for you.
So if you want to set your temps in the filament config.g then put a dummy setting in your PS start code.

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.

@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:

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?
