BBL just wrote that I will get spare parts… I can’t wait to have it finally fixed! 
I looked into the Sunlu S2. But first I will wait for after the repair.

Do you know the problem was, what parts they are sending for you to replace, and what caused it to break/wear out in ther first place?
Not yet but I hope that the new parts will fix it. I can’t imagine that there was too much wear because I printed less than 5kg. But who knows…
I will get the carbon tube assembly.
I’ve had a quick glance at the wiki. It seems that the print head clamps around a couple of linear bearings (I think they are plastic sleeves) that run on the carbon rods in the x direction, the axis you have problems with. When you have what they send you, it may pay to dismantle the hotend carriage on your existing p1s, and disassemble the clamps. You may find something there hindering the movement. It could save further dismantling, and you would have some spares. Depending on what they send, you may have to dismantle that anyway.
Hey debonr, I did get the entire carbon rob assambly and after replacing it the prints are looking great again.
Unfortunately some BBL filament is giving my trouble. For example this blue PLA filament is the worse!
If I have some spare time I will try to take my old carbon rob assambly apart as you mentioned. I curious if it is “broken” or if it is just dirt…
I’m pleased it’s fixed. All spools of filament can vary wrt the best calibration. Also humidity, ambient temperature, etc has an effect. I’m not sure of the consistency in quality with Bambu filaments, or many other ‘brands’. It probably doesn’t help that it can spend a few weeks in a warehouse, travels by sea for maybe a few more weeks, then maybe lingers in another warehouse for a while, all the time in varying temperatures, even before you see it.
hi,
what was the solution in you’re case? i have the same problem 
I got a new carbon rod assambly. Now the printer is working just fine again
I’m also having trouble with this process. My first step on the flow rate calibration worked fine, but the second step had adhesion issues. I’m totally new to this, and not sure where to go next.

This is not caused by bad filament quality.
Something goes wrong with slicing where the K value(flow compensation) is insanely high.
When i slice something without automatic flow calibration i get the same result even thoug the value i have set is normal.
And sometimes when i resume a print after a power outage that k value just changes right after i resume and ruins the print.
I still have no fix if i dont want to use automatic flow calibration. Hope this bug gets fixed.
Hi,
my calibration looks exactly the same, maybe a bit worse.
What resolved this issue for you? Changing the carbon rods?
Thanks
Hey, yes. After the HW fix the printer works perfectly again.
BBL sent me all replacement parts.The switch took a couple of hours though…

Thanks! Did BBL send you parts for free? Or did you pay for it?
For free. The printer wasn’t even a year old.

Same situation, mine is barely 3 months old. Did you submit a ticket here or contacted the shop?
I wrote a ticket and BBL send me a custom gcode to test the printer. After I sent them the logs they wrote that they would send me the replacement parts.

Thanks a lot, already submitted the ticket. Hopefully, I’ll get it resolved soon
Hi all. It’s an old post, but it’s a similar issue here.
I ran the Manual Flow Calibration on my P1S, using ABS but it never came with a smooth layer on the samples.
How to improve that?
5 is the best Coarse sample result.
Then -1 was the best Fine sample I got. But it seems rough for me.
The prints come out with a gap on the seam line, lots of holes, like stitches, around the walls, even from the base plate side, and the top layer is quite rough.
thanks for any help.
Do you have another spare Hotend/Nozzle to test? If not, try a cold pull and repeat your flow calibration
