BG203725422 I believe that the Bluetooth controller and its mainboard are shown as not compatible with the afterburner controller. If you refer to the afterburner website they list which controllers are compatible and which are not compatible

BG203725422 I do not know

BG203725422 I use file clips

BG203725422 No

BG203725422 Not sure about the carborundum glass, but I have 4 of these glass beds and use the un-coated side with a bed adhesive, gives very nice smooth finish to the parts. Let the glass bed fully cool down or I even put it my freezer before removing the prints, mostly they just pop off and because the glass provides a tough surface you don’t get damage if z-height offset is a little off.

BG203725422 Newer Creality printers come with press fit gears on the extruder stepper motors and are a pain to remove, but you can achieve this and the original motor will work fine. If you want a direct drive unit this should work but mounts will need to be purchased or printed to convert.

BG203725422 You can print tpu easier with dual gear extruder, but you must adjust z-height adjustment and slow print speed to get any success, don’t go too soft as jams and retraction become serious issues

BG203725422 Yes, you may need new stepper motor as Creality push fit extruder gears and you also need to adjust e-step values

BG203725422 Yes, but remember you may need a new stepper motor as Creality use push fit gears and adjust your e-step values

BG203725422 I don’t know sorry
