If support told you to open the base up to check on the status of the SD card, and re-insert if necessary, then your warranty should still be valid. It’s only when we fiddle with bits without explicit instruction that it is null and void!
And as goldernsake said… the printer is in error before the calibration. That is simply a movement test… it should do a full clockwise circle, and an anti-clockwise circle, and then move the head up to heat it before calibration. Make sure you put the grease lubricant that came with the printer on the ball joints, and that they are firmly locked into their magnetic joints. That happened on my first few prints with the flux delta, but it has since worn in and I haven’t had any joint-popping issues since. Add a bit of the grease to the vertical rods also (the two silver rods either side of belt-drive on each corner. That will help protect and lubricate that also, as it has slider bearings running along it.
It might be worth simply running the calibration and movement tests directly a few times before you do your first print… that will get the grease spread out and give you a chance to see that everything is locked in properly. In Flux Studio, goto Machines -> [your machine name] -> and use either the Run Auto Leveling or Commands -> Run Movement Tests options.
