My Anet A8 lacked the aluminum bracket to which the extruder is mounted. Luckily I got refunded in total, got a friend to print me an E3dv6 carriage and went with bowden setup. I haven’t had but problems with that printer, I spent more time fixing it rather than using it in the past two/three years. There is always something not working, something about to break, something to be repaired. The board and the heated bed are an heat hazard, I’ve personally seen a friend’s a8 coming with an extruder which would clog every couple minutes. The frame is not stiff and vibrates a lot, the stock carriage is barely held up by the two z axis motors, weighs a ton and often unalligns itself during the print. Different extruders would randomly clog even with esteps and flow calibrated and no heat creep.
I got mine for 100€ and got refunded in total because a crucial piece was missing, but for 200€ you’re better off waiting for a nice offer on a ender 3. I wouldn’t recommended thatprinter to my worst enemy.
Also nice that my first lemmy comment is me crapping on my anet a8.
They are 22ohm resistors. You can see they are resistor by the marking R on the pcb. The first two digit is the value (22), the last is the multiplier (0), so it would be 22*10^0 =22 ohm
