you don't have to set g-code. G-code is the default for all slicers.
just slice and either save file to sd card - qidi has sd card slot. Or print over usb - I only do that for print times under 30 minutes.

The sd card means you just need a power socket and can take the printer anywhere with files already lodade on the memory card.
The delta also has a full size sd card slot built into the control panel. A lot of printers seem to have micro sd card slots - and those things are so tiny they often get stuck in the wrong part of the machine :-)

Setup is basically take it out of box. Bolt on extruder, put hat together, attach tubes, plug it in, picka language and follow the on screen instructions.
The welcome script guides you through: calibrating bed, nozzle calibration, loading filament and other stuff.
Very friendly and easy to use machines.

First time I fired up my creator I was amazed - it basically talks to you (in text). Loved that :-)

All slicers use g-code. So you're not limited.
