Hello. Running the risk of sounding foolish, I’m pretty new to 3D printing. I’ve learned much, but likely making a mistake somewhere. No matter which filament profile I choose (PETG, PLA, PLA-CF, TPU, etc.) the bed temperature always defaults to 55 degrees and the nozzle temperature always defaults to 220 degrees on my X1C. I created a custom filament profile with the minimum nozzle temp at 230 degrees and the maximum at 250 degrees, and still the print wants to resume at 220 degrees nozzle temperature on the printer. I can manually change the print bed temperature and nozzle temperature eventually when the print starts, but I assume that everything else (fan speeds, Volumetric speed limitation, etc.) have not changed. When printing PLA or PLA-CF with the default temperatures, my results are very good and fast. I like my X1C very much. Any help and direction are very much appreciated. Thank you all very much.
Thank you for the response. That is exactly what I have done. It seems like the X1C is ignoring it and defaulting to 220/55 degrees. I tried setting up a custom profile with Recommended nozzle temperature between 230 and 250 degrees and First layer and other layers at 230 degrees. I set the Smooth PEI Plate/High Temp Plate to 70 degrees. It still sends the print to the X1C over LAN only mode, but defaults to 220/55 degrees. I have even tried reloading Bambu Studio to no avail. Seems like there is something I’m missing. I guess I could set up a ticket, but I wanted to try to avoid it if I could.
Are you starting with a previously saved project?
Or a new stl file, then make your changes and slice to print.
Hello Barryg41, and thank you. Almost always a new project. I have even reinstalled Bambu Studio and same result with a fresh print. It doesn’t matter whether I click on a desktop icon for an .stl/STEP file or open it from within Bambu Studio as a new project. I did submit a ticket to BL, so I’m hoping for a resolution,
Hello again Barryg41. The thing I don’t understand is this. I have all PLA in my AMS units. But I have PETG on the external spool. When I click the icon to the right of the PETG filament in Bambu Studio, it is showing the “Recommended nozzle temperature” as 250 (min) and 270 (max). Under “Print temperature,” the nozzle temp for “First layer” is set at 255 degrees, and “Other layers” is set at 255 degrees also. The Engineering Plate, Smooth PEI Plate/High Temp Plate and Textured PEI Plate temps are all set to 70 degrees. When I print I have the external spool set up as PETG, which should be using these settings. But every time, the printer displays 220 degrees nozzle temperature and 55 degrees print bed temperature, not the 255/70 degrees as outlined in the print profile for PETG. I haven’t done anything special before slicing, just clicking on “slice” and then “print” and unchecking the AMS so it will default to the external spool that is set up as PETG. I don’t know if this explains things any more clearly, or if it displays something that I don’t understand yet. But I appreciate any help to clarify if it is my machine or my brain. Thank you again.
Seeing this type of error. A lot of experienced users recommend restoring to factory settings. And are you using the latest firmware? If you are not, I would at least try to update and with a 30 second power cycle after you do this upgrade.
I am just grabbing at straws. I have never heard of this problem.
Thank you again. Much appreciated. I forgot to mention that I am using the latest X1C firmware ver. 1.06.00.00. I noticed in the X1C version history that there is a version 1.06.05.00, but I haven’t been notified about that update, and I don’t know how to force it. I have also tried to reset to factory default twice. I tried researching the heck out of this issue, and I could find nothing. Very strange. Well, I have a ticket in now to BL. Hopefully hear shortly and be able to get to the bottom of it.
Why is the default bed temperature set at 35?, all my other printers are set at 55-60 for the bed temperature for PLA.
That’s BBL default for the cool plate.
Hi New23d,
Sounds like you didn’t change your model to the filament on the external spool. When you import a model, it is sliced with the first filament of your filament section. Right-click the model and click on “change filament”.
Hello Skyme. Thank you very much. I heard back from Bambu Lab support. They were helpful and gave me a similar response (click on the number of the filament you desire), although this is excellent! For me, it’s a matter of not knowing what you don’t know. Wish the X1C came with a thorough user guide like most electronic items. Love the printer, and I’ll continue learning. Thanks again. Appreciated.
Is that 35°C just for Bambu filament?
I have been using Polymaker Polyterra with the same temp on the cool plate.
Saying that my very first printer did not even have a heated bed to start with and PLA stuck down just fine.
It’s default for all PLA on the cool plate.
I agree with you about the user guide, I was shocked when I bought my X1 Carbon as all it came with was the quick start guide which has nothing whatsoever relating to setting up the AMS, I thought it would come with a book like my Prusa MKIII did, I managed eventually to set up the AMS, what was throwing me was the bag of pre-cut Bowden tubes, I initially thought that I had to fit them to the AMS, would it be so hard to put on a sticker saying “Spare Bowden Tubes For AMS”?
Bambu PLA, Bambu bed, Bambu printer. PLA does not stick to the bed at 35. I’ve always printed at 55-60 on the bed for PLA. Why did they pick 35 as the default? And why can’t I change the default.
Nothing is supposed to stick to the bed - except a plate. Which plate are you using? If it’s the Cool Plate, wash it with dish soap (IPA is not a substitution for that but you can use IPA later, between prints). If it’s some other plate, be sure to select it, and a proper temp will follow suit.
OK. It doesn’t stick to the plate. The Cool plate, because I am printing PLA. It did it to me on the very first print on a brand new machine. Your experience may be different, but for me, PLA does not stick to the PLATE at 35 degrees.
With that out of the way, I will ask again. Why did they pick that as the default, and why is there no way to change the defaults?
Obviously because it’s the correct temperature for that plate. The whole point of the Cool Plate is it’s almost not heated (less energy used, less cooling needed) and hence its name. I can assure you it works wonders if you clean it like I described. You do need to clean brand new plates from most brands, just like you commonly need to dry hygroscopic filament right out of the vacuum seal despite the silicant bag also put in there.
If you dislike the plate, use a another one, such as the Smooth or Textured PEI and tell the slicer what plate is installed. The temperature will default to 55°C then.
The question you probably mean to ask here is “how do I change the defaults?”. I wouldn’t recommend using the Cold Plate at higher temperature but you are free to edit a filament profile and bump it to 60°C or 110°C if you like. Good luck with that. If you insist, you can have 55°C for the first layer and 35°C for the rest.
If you don’t own a Smooth PEI / High Temperature Plate, I recommend them (Bambu’s). They are excellent and their normal temperature is 55-60°C for PLA (default 55°C and yes you can change it).
Thanks for the suggestion. I had tried using the Engineering plate, but the sofware refused to slice. Selecting the PEI plate does what I want.
