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):
;----------------------------------------------------------------------------------------------

if move.extruders[state.currentTool].filament == "ABS" ; if ABS is loaded

;--------------------------------------------------------------------------------------------------------
; hotend-temperature.g
;
; Description:

; - called to auto-select the hotend temperature according to the loaded filament
;--------------------------------------------------------------------------------------------------------
if move.extruders[state.currentTool].filament == "ABS" ; if ABS is loaded

This is how the variables are defined in config.g:
;----------------------------------------------------------------------------------------------------------------------------------------------
; 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!
thank you very much for your help along the way!!!
