wrong temp showing on job  

RE: wrong temp showing on job

Can you give a few more details please.

Which slicer are you using?, machine details (model, age, prebuild or kit)

Does it do this with all files, or just one particular file.

Maybe upload the file and someone can try and see if they get the same results.

Afraid I cant as don't have my MK3 yet, but sure someone will assist 😉

Its a brand new Prusa i3 MK3S+

 I am using Prusa slicer and have successfully created a few conversions to PET From PLA files and everything transferred fine , It has just stopped carrying over the correct temperatures on all PET files

What printer is it ?  I know you have posted in the mk3 forum but it’s normal for the mini profiles to preheat to a lower temp before it does the bed levelling etc.  Also some of us with the mk3 use a 2 stage startup that does the same, preheats to around 160-170 first.  This allows a better level while keeping the filament from oozing out. 
If you save up one of your projects, zip it up so it can be attached here, then we can look at the printer profile and see what’s in your start code.

I meant to save your actual project file (File >Save as) which saves a 3mf file with all your settings as well as the model, any special custom gcode you might have etc.  For future reference its the single best way to debug any issues.

However in this case the generated gcode actually has most of the settings at the end of the file.  As I mentioned in the previous reply the MINI profiles are designed for a 2 stage start up.  You sliced that gcode with a mini profile.  Its mentioned in the end block.  The start gcode section also contains the following which is normal for a mini -

; start_gcode =
G90 ; use absolute coordinates
M83 ; extruder relative mode
M92 E317 ; set steps/unit for extruder
M104 S170 ; set extruder temp for bed leveling  <-- This line sets the initial 170 degrees which is why you see it heat up to 170 first.
M140 S[first_layer_bed_temperature] ; set bed temp  
M190 S[first_layer_bed_temperature] ; wait for bed temp
G28 ; home all without mesh bed level
G29 ; mesh bed leveling <-- Here it will do the mesh leveling
M104 S[first_layer_temperature] ; set extruder temp  <- Here it will heat up to your filaments set temperature
G92 E0.0
G1 Y-2.0 X179 F2400
G1 Z3 F720
M109 S[first_layer_temperature] ; wait for extruder temp 
; intro line
G1 X170 F1000
G1 Z0.2 F720
G1 X110.0 E8.0 F900
G1 X40.0 E10.0 F700
G92 E0.0
M221 S95 ; set flow

If you just let it print it will do its mesh leveling and then once done it will heat up to full temperature and then print the prime line and continue with your model.  This is perfectly normal and in the instructions for the Mini I believe.
