Printer ignores Gcode pre-print
-
Hi there!
I created a system file that can be executed as print from different macros (i.e. printer calibration macro or first layer calibration macro), called first-layer.g. This system file contains instructions to print a square that will allow to use babystepping for first layer calibration and then stores the resulting value in config-override.g. The gcode itself has been generated via Prusaslicer and I added the start and end bits.
I'm using a Duet Mini and I'm currently on RRF 3.4.0 and DWC 3.4.0
This is how first-layer.g is being called via the macro "First Layer Calibration":
;------------------------------------------------------------------------------------------------------------------------------ ; First Layer Calibration ; ; Description: ; - macro file ; - calibrates the first layer distance between nozzle and bed ; - stores result in config-override.g after print completes ;------------------------------------------------------------------------------------------------------------------------------ M291 P"Do you want to start calibrating the FIRST LAYER?" S3 R"FIRST LAYER CALIBRATION" ; requires user input M32 "0:/sys/first-layer.g" ; executes "first-layer.g" from SD card This is first-layer.g (removed most of the Prusaslicer generated gcode as I do not think it is relevant for my problem):

;---------------------------------------------------------------------------------------------------------------------------------------------- ; Global Variables ;---------------------------------------------------------------------------------------------------------------------------------------------- ; Filament Temperatures global abs_hotend_temp = 240 ; global ABS hotend temperature variable global abs_bed_temp = 110 ; global ABS bed temperature variable global greentecpro_hotend_temp = 230 ; global GreenTec Pro hotend temperature variable global greentecpro_bed_temp = 60 ; GreenTec Pro bed temperature global pc_hotend_temp = 270 ; global GreenTec Pro hotend temperature variable global pc_bed_temp = 110 ; global GreenTec Pro bed temperature variable global petg_hotend_temp = 235 ; global PETG hotend temperature variable global petg_bed_temp = 80 ; global PETG bed temperature variable global pla_hotend_temp = 210 ; global PLA hotend temperature variable global pla_bed_temp = 60 ; global PLA bed temperature variable global tpu_hotend_temp = 230 ; global TPU hotend temperature variable global tpu_bed_temp = 60 ; global TPU bed temperature variable The problem I am currently facing is that both M98 commands who are supposed to call bed-temperature.g and hotend-temperature.g before the print are being ignored and the printer tries to start printing without the hotend or bed being heated, resulting in an error.
Can someone help me understand what I am doing wrong?
Thanks a lot!

@flobler OK, I figured it out already
This was a stupid typo that I then carried from bed-temperature.g to hotend-temperature.g via copy paste. I tried all these files with PLA previously which worked fine. This time I had PETG loaded but unfortunately looked for PTEG in the object model and not PETG.
Therefore the loaded filament and my bed-temperature.g and hotend-temperature.g system files did not match and therefore not use PETG temperatures before trying to start the print.
Sorry for the noise
