Investigation discovers the surprising result that slicers introduce more error into prints than the printer itself.
Printers have become appliances instead of a hobby.
Nowadays you have: Push button -> get thing.
Instead of a 30 minute process of leveling the print bed, 4 different pieces of software to get the gcode correct, a specific time, temperature, and humidity level filament needed to be kept at, a custom enclosure to prevent the draft from walking across the room causing layer shifts, and a prayer to the ether that there wasn't some type of fault on the SD card that would corrupt the gcode and gouge your brand new tempered glass bed.
