I recently got my new X1E and have done some prints. After around 120 hours of printing, the process stopped with the following error: 0300 8010 065030 - Hotend Fan RPM not normal.
I tried cleaning the fan, but there was no debris or blockage. I spun the fan a few times with a pen. When I turned the printer back on, the fan made some terrible noises, and the error code changed to: 0300-0300-0001-0001-080630.
I’m still waiting for a response on my support ticket from both the seller and Bambu, which doesn’t give me a good feeling.
As a technician, my initial impression was that the fan had failed, so I used the maintenance kit to swap the 0.6 hotend fan onto my 0.4 hotend. The printer is back up and running now.
After some research, I found that many users report similar issues with the hotend being too hot for the fan, which causes the fan to fail. I’ve only been printing with PETG-HF, which is what I primarily use.
Also, I wanted to ask about the LiDAR module of the X1E. Is it normal that after around 18-24 hours of printing, I get a warning to clean the lens? I’ve noticed that this message pops up about every 20 hours of use.
Now, my question is:
What is Bambu’s recommendation for using the X1E with PETG-HF?
Should I print with the glass top on or off?
Should the door be open or closed?
The PETG-HF is printed at a maximum of 260°C, and since the printer is capable of 320°C, I believe this shouldn’t be an issue for the fan, even with the enclosure fully closed.
Longer print jobs result in continuous heat generation in the print area, especially at the hot end. The hot end fan is responsible for dissipating this heat. An insufficiently high fan speed can lead to inadequate cooling, which in turn increases the load on the bearing due to excessive heat.
Yes, that was the other option I considered. However, I would give the same answer. How warm does the fan really get? I never reduce the hotend cooling, I always leave it at the default settings for the filament. I have never had any fan problems at the hotend, not even with PAHT-CF, which also requires high temperatures. Some fans are already out of order on delivery, I have already experienced this. Three in a pack work, the fourth doesn’t. Perhaps it is simply a quality problem with the fans installed.
I am curious to know what the solution to the problem or the cause of the problem is.
Does anybody know where I can get spare parts for the X1E?
The fans and hotends available in their EU shop don’t seem to have the right connectors.
I would like to have some spare parts laying around.
Bambu provides somewhat conflicting guidelines.
The Bambu Filament guide recommends printing PLA, PETG, and TPU without an enclosure. These are filaments that print well on open printers.
The Wiki guide to build plate settings recommends removing the top glass if the bed temperature for PETG is >70℃.
The PETG-HF technical data sheet says chamber temp should be 35-50℃. It also suggests a bed temperature of 65-75℃. You won’t see a 50° chamber temp with a 75° bed and an open enclosure.
I’ve not tried PETG-HF, but my personal experience with PLA, PETG, and TPU is that open door/top off works well, with one exception. If the chamber is too cold, the filament cools too quickly and may not adhere to the plate or to itself. I only partially heat my shop in winter, so I preheat the closed chamber to 26°C before beginning to print and then monitor the temperature, opening the enclosure when it rises above ~36°C. I’ve also had PLA and PETG failures when the chamber was too hot, so open chamber is my preference for these filaments.
The fan problems are just that, defective fans, not improper operating temperatures.
The reseller that you bought your printer from is probably your best first contact for spare parts.
That being said, The X1E has a bit of a mashup in parts from the P and X series. The hotend fan from the P series should work as a replacement for the X1E.
Yeah, i was confused too. All information are conflicting.
I did some prints now and the extruder temperature does not go over 255°C and chamber does not get any warmer than 35°C.
Soooo I guess the fan on my first printer was just bad from factory.
