Printing starts without homing and setting extruder temperature

GCodePrintr

Hi, I’m using the beta version 3.52 and I’m trying to print a file generated with PrusaSlicer.
Despite extruder temperature and homing set in the GCode file, GCodePrintr only waits for the bed temperature and then immediately tries to start printing with a cold hotend.

The beginning of the GCode file:

; generated by PrusaSlicer 2.3.3+linux-x64 on 2022-08-15 at 21:44:29 UTC

;

; external perimeters extrusion width = 0.45mm
; perimeters extrusion width = 0.45mm
; infill extrusion width = 0.45mm
; solid infill extrusion width = 0.45mm
; top infill extrusion width = 0.40mm
; support material extrusion width = 0.35mm
; first layer extrusion width = 0.42mm

Additionally, how do I avoid the sample file being loaded at startup?
It’s larger than my print size, so I always get an annoying warning at start.
