Creality's horrible support is moving me towards saying AVOID THIS COMPANY AT ALL COSTS. DO NOT BUY! If you must buy a Creality printer, do not buy from Creality directly!

It looks well made. You're a bit unlucky with the error. I hope you get it sorted soon.

Oh, definitely no complaints about the build quality. And quite simple to put together. Just wish it worked! I've got to the stage where those 110 errors stop (they still occur several times after powering on), but now it's complaining about "abnormal nozzle" ... the nozzle doesn't feel like it's heating up at all ...

Update from Creality support: I'm sorry that this problem happened. Please check if the wiring on the motherboard is loose, and re-plug the cable terminal connecting the motherboard to the nozzle adapter board. If the wiring is not loose and re-plugging does not work, please contact us again, we can send you a new motherboard for replacement.}

The ADC-TB might be the thermistor for the hot bed, Ted Bemperature? Your issue seems more deep seated than a dodgy connection anyway. I'd take up the offer of a new mainboard, or a new unit.

Yeah, once you get passed the 110 error a few times, it stops and then becomes a permanent "abnormal nozzle" error (never heats up). Can't see any cabling issue ...

Well I'm late to the party, I didn't see this video come out. I'm pretty sure that the problem lies with the toolhead CAN Bus card, or the cable. So I would take the cover off of the toolhead and check the connection there first. If it's connected up then you are going to need some new electronics. But at which end? Disconnect the cable in the somewhat misnamed RS232 connectors (there are two of them as seen @7:14 where your fingers are. I'm referring to the one in the foreground with the Black, Green, White, Yellow & Red wires. The one in the background is most likely a stepper motor connector that got mis-labeled) and connect your scope channel #1 to White & Green, and channel #2 to Yellow & Green. If my guesses as to which wires are which are correct, it will show a pulse train coming from those pins. Reference AliExpress for a decent picture of your board: www.aliexpress.us/item/3256807031611129.html BTW, it sure looks like one end of the connector is not completely in its socket. But it's not out by much. An easy way to figure out which wires are your signal wires in a CAN Bus network is to take an ohmmeter and look for the pair that shows ~60 ohms (if you get 120 ohms then your cable is disconnected at one end). That should be the CAN High and CAN Low wires which would have a 120 ohm resistor at each end. Or if it's actually engineered properly, a resistor that matches the characteristic impedance of the cable. AB used to use 86 ohms for its "Blue Hose", later on it was 121 ohms for the cursed DeviceNet. GE used 150 ohms for its Genius I/O. Seeing as Creality didn't even bother to use a cable, I'm not sure what it should be. The Creality "110" error has just a "/' for its description, but based on the errors in the "110" range, it points to the toolhead. Which would explain why you aren't seeing a nozzle temperature. But it boggles the mind that Creality doesn't know what their own error code means. I would rate Creality slightly higher than FLSun. But that's like comparing the guy who beats his wife to the guy who beats his wife and his dog. I've owned both BTW. The FLSun came in non-functional, I had to build my own firmware. The Creality came in working, but the POS extruder/hotend kept accumulating plastic and had to be disassembled and cleaned monthly. I got tired of that nonsense, and gave it away. So pull the cover off of the tool head and check the connections there (look for a lit LED while you are at it), or better yet, pack it back up and get a X-MAX3 like mine. No more talk of this Bambu shit BTW. :)

fun n games.. i was gonna say take it back n swap it..seems the mainboard has issues...but... china... shoulda grabbed one from jaycar! ..and fully agree with ya rant!...im forever gettin hit like that..."aus stock" yet its drop shipped from china...SMH

Firmware in screen probably needs updated via sdcard to suit the new motherboard firmware you uploaded?.

I should be able to return it to the warehouse in Sydney ... even though it didn't come from there!
