People who have had support say they know it could be the firmware ect. Can you post the ticket reply on here so we can read it.
Im not changing my cold plate sticker as they advised as is nothing wrong with it.
Its also weird that mine will print to the textured plate but not the cold plate.
Also that the same part printed before ths update had nice smooth top layer and now any parts with a radius top are awful even ones printed before.
Simple parts like a dust extractor adaptor i made on ths textured plate today run totally fine. I dont have a clue and havd just concluded i hope a new firmwRe comes and resolves it.
Really sad for those of you who cant even print on the textured plate. Glad i bought it though.
My X1 does that and definitely did before the last firmware update. The printer needs to home because it has just turned on or idled long enough for the motors to turn off. It starts homing by lowering the bed a bit so the nozzle canāt possibly plough tracks in it. If the bed is already at the bottom it grinds against the stops making a horrible noise.
If a print ends with the bed at the bottom I always manually lift it at least 20mm before homing or starting another print.
Not sure what Bambu can do about that other than do that lowering at low motor current, but, maybe they already do. Maybe they could put up a warning asking to be allowed to raise the bed and not turn off the motors when the bed is at the bottom.
If you mentioned the bed grinding into the bottom that is probably what Bambuās comment about raising it 10-20mm was about.
This is not entirely correct. Bambu staff already confirmed this is a firmware bug that will be addressed in the next update. This is a big issue and would have otherwise been prioritized on this previous update, also why there is no status of this in the past for automatic, at least that I can find. Now this is a common issue that is easy to find throughout the forums and Discord.
The software knows the height of the print and bed, therefore it would require a check on that prior to lowering.
I know what the 10-20mm was regarding, the part that is odd is when they stated that was to avoid using home too much. Its just odd the way that is worded. It sounds a bit like they are saying ādont home your printer.ā
Underlying point is they should have addressed the issues in this thread. Not sure why this firmware update was pushed so hastily. By far the worst one yet, with many unable to use theirs, and others having various forms of issues.
The printers have tried to drive the bed through the floor from the day they first shipped. The only firmware thing that may have changed is timing out and disabling the steppers after complaints about too much idle power consumption. Once motors are disabled the printer can not make any assumptions about the position of any axis so lowering the bed into the bottom of the machine likely occurs more often than it used to.
If you or they think it is a bug tell me how you think they are going to fix it.
As for hasty firmware update again I will say there is an absolute minimum of 6000 X1s out there, probably 10,000+ and a bunch of P1Ps and 99% will have had this āhastyā firmware update yet only a handful of people are complaining and blaming the firmware update for (to quote you) āvarious forms of issuesā. A small proportion of users having a variety of issues does not point to a single cause.
If there is a common issue it seems to be a first layer adhesion problem that affects very few printers and no one can identify a specific cause for it.
Come on now lets not fight between us. If your prtiner is working amazing and well then thats great. Understand people that have issues though will be frustrated and with no resolution its hard for people not to get annoyed. It is the problem with adopting early and i dont regret my purchase as i truly love the X1 machine. I do just hope i can go back to being able to print onto the cool plate again and the other upper surface issues im having go away as i didnt have them in the past with the machine.
Iām one of the lucky ones but am still throwing ideas out there, reading, and paying attention to what others are doing or are having issues with
The frustrations others are experiencing is understandable but we donāt need to get snippy with each other
Iāve been able to assist with a few issues others are having and my hands are tied with more complex issues like firmware not jiving with some machines
I still believe that there was a bad batch of components that were inadvertently installed in some printers with my current train of thought being the possibility of bad processor boards that are not accepting the current firmware
If it was soley a firmware issue absolutely every printer would have the same negative affect from the update but thatās simply not the case
Then again my other printers are cheap junk to begin with and Iāve updated or replaced anything from stepper motors, threaded rods, smooth rods, GT2560 boards, power module/voltage inverters, hot ends, extruder motors, ahhhhh the list goes on and on
With all of that I realized that some components or printers in general were definitely built on a Friday and when it comes to mass production absolutely every manufacturer of every single thing we use in this world has its hiccups from time to time
I also believe that BL will sort out these issues and continue to grow while showing other manufacturers how its done, this is a young company and unfortunately growing pains are to be expected
Is the front door closed and top glass in place during the first/calibration layer?
Iām assuming you have already ensured all slicer settings are set to their defaults?
Forgive me, too many posts in this thread, but what filament are using? Have you tried using Bambu filament for a sanity check and to eliminate āvariablesā?
Being blunt, no need to reply. Hopefully the questions might help highlight something that might have been missed, etc. Good luck. I can feel your frustration and wish you the best of luck.
My X1C works pretty well before and after the last firmware update.
Of course people have issues. 3D printing always has been a can of worms requiring endless arcane fiddling and tweaking and modding to get them working nicely. I was put off buying one for many years because I didnāt think it was worth the hassle. The printers have got better (Bambus being a good example) and I have more spare time so now I am fiddling with them as well, but, it is just a smaller can of worms.
So I donāt deny people have problems. I just donāt see how many or perhaps even any of those various problems can be attributed to the last firmware update. Bambu know what they changed in the last update, they get much more feedback than we see here, they have beta testers. If there really is something wrong with the last update it must be a really obscure and complex issue for them not to be able to identify and fix it.
Filamentry attributing the bed grinding into the bottom of the printer problem to the last firmware update is an example of the update being incorrectly blamed.
I hope everyone gets their problems resolved but just blaming the last firmware update without being able to identify what that update actually did to cause the problems isnāt going to help.
That argument āMine works so every single one shouldā is just invalid in everything tech related. I have already had this argument with other people on this thread but I will just attach this picture to provide some proof of what I am saying when I tell people I tried everything and nothing worked from day to nigth. The only difference between working and not was the firmware. The printer simply stopped sticking to whatever bed, with whichever material or nozzle, like magic.
Been away, but I see Fletch said not to fight, to which I apologize if it seemed that way. I find that many ideas come from the basics of conversational discourse; meant nothing by it.
On that note, regarding the Z axis, if the printer knows the top and the bed thickness, then it can know its height. Even if the motors do use a form of power saving and the board does not currently hold the data, it could easily be implemented in a few ways.
When the printer is complete with printing, it can write to internal memory the last state of its height. The printer already saves a lot of data for export logs, a kb or two isnt hurting anything.
Write it to the SD Card (NOT PREFERRED). While re-writing data to a chip can wear down the life, it takes a lot and is not worth writing to an SD card.
When a print finishes, use the build height of the end print and the total thickness of the plate to determine intervention, etc.
Pre-determine if the plate can be re-printed / homed based upon the files height during the initial calibration and setup process prior to the print starting. If it is beyond 170mm, dont allow it, or have it home first (user choice).
Overall a few ways to fix this, its just a matter of doing it.
Right up until someone removes the build plate and puts it back or swaps out. You just changed the Z height, especially if someone accidentally gets some debris between the build plate and heat bed.
Different build plate temps will also change the Z height. That is a big piece of aluminum that has a stupid high heat expansion ratio.
My printer is now working fine as well after the hotfix to the firmware. Tried both PEI bed and cool sheet and itās back to normal. Already did 4 prints and working flawlessly
To clarify, when I refer to the ābuild plateā, I am doing so in a general sense of the entire platform for the z axis, not limiting to the magnetic build plate. This is also why I used 170mm in the example. Past a certain depth it should rise then home and disallow the re-print, home, or lower by 10 options.
One new thing i spotted today when using the textured plate with the rolled back firmware as i didnt have the textured plate before is the machine saying first layer detection isnt available for the current print.
