So I kept getting issues with my filament being unable to finish unloading, come to find out I had a peice of filament broken off in the extruder.
Easy enough fix, I pull the PTFE tube out of the top of the extruder and remove the filament.
Just to be safe I thought it would be good to replace the hotend as well. No problem, right???
I take out the 2 screws holding in the hotend and start to remove the cables for the heater, fan and thermistor.
I unplugged the 2-pin plug of the ceramic heater, then the 4-pin plug of the hotend cooling fan, and then when I tried to unplug the very small 2-pin plug of the thermistor, they entire plug and connector came loose from the mainboard.
I can say that I used the same force to remove the first 2 connectors that i did on the thermistor.
I am a bit dissapointed that this happened. I have only had the printer up and running for 4 days.
I have put in a support ticket, but am still waiting to hear back from Support on this issue.
Has anyone else had a similar issue like this yet?
yup. I had the same thing happen when changing nozzles. They will have you take a picture and a picture of the QR code on the lidar. So you may as well add those to your ticket. then they will send you a new board. take about 10 days to get and then you are up and running again. mine was also about a week of owning the printer. and ive changed many of nozzles as I have 10 bambu printers.
Had that happened to me, but with the connector to the filament sensor on the extruder. Surface mount connectors don’t have a lot of strength. Overall, I have been very impressed with the printer, but the serviceability leaves a lot to be desired. I had the stand-offs for the heatsink come off the MB and they are sending me a new one.
I agree, overall I am very pleased and impressed by this printer so far (Only 4 Days).
I have had some of the best prints I have ever made come off of this printer, and the ease of use if amazing!
Just dissapointed that something that should have been so simple, replacing a hotend, has now put my printer out of commission, for who knows how long.
Not to mention too, I still have yet to receive an actual email from Bambu stating that they have even looked at my support ticket yet.
That is unfortunately looking like the same lack-luster customer service that was also involved with the lack of any shipping info for the printer.
All my tickets, except for the last one, were responded to within two days. This last one took over a week. After I sent another message asking about the status, I got a reply a day later. They said there was some kind of system glitch and the original message to them got lost. You might want to try adding a message to your ticket incase your ticket got glitched.
I should be getting a replacement board in the mail today!!!
Here’s the entire process so far, for anyone else who wants to know:
3-22 - I had the issue and put in a ticket with support, including a couple pics I took of the board and the connector that came off.
3-23 - I got a response back (actually pretty surprised they got back to me this quickly) asking for an additional pick of the bad board with a provided warranty claim number in the pic.
3-23 - Response from Bambu was in 6 hours of the last communication with an order for a new board being placed. (Very nice)
3-28 - Notification from Bambu that the order had shipped with tracking info.
3-30 - Notification from USPS that the part is out for delivery!
Overall, the support on this issue has been outstanding! At first I was really disappointed simply because I had only been able to use it for less than a week, and now its been down 8 days, but realistically to get a support ticket processed and a new part shipped out to me in 8 days is outstanding service!
But I am happy with the fact that the technical support has been a great deal more informative than the sales support was after ordering it.
A suggestion for Bambu, which hopefully in the near future will be available, would be to offer the boards as replacement parts in their store.
I kinda get that the printer(s) are just fire right now, and more than likely all parts are going to be put towards the new stock that are going out as fast as they are being made.
So hopefully in the near future that will not be the case, and we will be able to have these parts on hand.
They added two new AMS parts in the last couple weeks and a new heat bed cable in the last few days. I suspect more replacement parts of all kinds are coming soon.
I just got the toolhead v9 board delivered, took about 10 minutes to get it in and everything buttoned back up, running calibration now, I should be back up and slinging plastic in minutes!!!
Thank you again Bambu Technical Support for the great service and quick turn-around time!
Hello, I have the same problem, i‘m waiting for an answer from the support. When the new circuit Board is delivered, I think I have to spend some hot glue to the connector to prevent it from breaking a 2nd time. It‘s not well constructed, maybe a greater connector at this tiny cable will solve the problem better than glue. Has anyone an idea to protect the connector before he breaks off? After all, this connection is often plugged in.
I dont‘t know the type of this little Connector. Someone who knows that?
This also happened to me 2 days ago. I already contacted bambu support, been 2 days and no response yet. Really a big bummer as the v9 (or v8) board is not for sale on their website so I’m forced to wait for customer support to deliver me a new board.
After taking a look at their wiki it seems there is a warning about this on multiple pages.
under Operation Video (the 2nd paragraph) on the Replacing the toolhead TH board assembly page
under Step 6 (also the 2nd paragraph) on the Replace the toolhead boards (V9)
I can’t post links as this forums does not allow
Even tho it is on wiki I still believe this is not a smart decision when they were creating the board as it’s very normal for the end user to try to disconnect this connector the same way they would disconnect the other two which would actually end up on the connector breaking.
really hope they add both boards to the site asap as I don’t even know if CS will be able to help me if this happens a sec ond time.
Placed a ticket last Wednesday for this issue and have not had a response yet… if the board was available for sale I’d definitely just have purchased one and kept the warranty board for a spare whenever the ticket was resolved. I’ll keep waiting for a response.
Same here, but to be fair Bambu has published in enough places that this connector has a clip. I ordered a new board V9, only to realize I have a V8. Contacted support, they told me I will need both the front and rear V9 boards and that my Lidar would not be compatible. They then said if I purchased the boards they would send me the lidar as a 1 time complimentary service. While waiting for the parts I managed to get the plug connector back onto the board.
