I’ve had an X1-Carbon for a few months now, and after a hundred or more prints, haven’t really had a problem. However, I went to print some products today, and suddenly my prints look terrible in quality. Does anyone know what is happening here?
The bottom of the prints show all of the extrusion lines (wasn’t a problem previously), and the top of the prints looks pretty rough to the touch. These were printed with a smooth plate and a .6mm Bambu nozzle. It’s ABS with the default settings (which always worked great previously), and the filament was dried before use. I’m at a complete loss as to whats happening here, and could really use some help.
Summary –
Pre-dried ABS (previously used with no issues)
.6mm Nozzle (previously used with no issues)
Default .6mm ABS settings
Clean smooth plate
Chamber preheated to 60C, bed at 98C, Nozzle at 270C
I seem to be having a similar issue printing PLA basic for some prints that ive previously printed many times. its like the top layer just goes to sh*t. i am also getting some really weird "nicks’ or “chunks” on hard angles. curious to see what you find as a fix. my buddy and i are going nuts over this. would a standard reset of the machine to default fix this?
Top layer issues especially near corners and edges frequently happen because the corner or edge is lifting off the build plate. You can sight along the part surface that was on the build plate and see a curve or looking at layer lines they seem compressed near lifting and surface issues if it’s the part not sticking.
What can cause lifting - if that’s the issue - are “dirty” build plates and/or filament moisture but YMMV.
Are you saying you used existing STL/STEP files OR existing 3MF files?
If it is the later try to slice the original files again.
For some reason Bambu seems to think turning existing 3MF files that include complete profiles useless at times.
If no originals you can try to just import the model geometry and slice them.
Hi, I’m also having a similar issue with the first layer.
I have my Printer a few months now and I use the smooth PEI Plate
At the Beginning everything went well using Bambu PLA and SUNLU PLA+
After I cleaned the Bed the issues began.
First Layer looks similar to this picture and what I’ve noticed is that if I have small circles, also like on this Picture or Grids, at some places the filament isn’t sticking on the place but it starts pulling a string and then gets to a clump.
Tried it with Bambu and SUNLU, everytime the same issue.
If I stop the print and restart it, it happens exactly the same at the same place.
Depending on what object I print with small details, this happens everytime at another place on the bed.
I recalibrated the printer already, but no change.
Filament is a few Weeks old in the AMS.
If the problems started after you cleaned the plate there’s a good chance something impure was introduced during the process. Can you describe how you cleaned it?
I used Dishwasher Liquid and hot Water with very light scrubbing. Then took Kitchenpaper and dabbed it.
In fact I cleaned the plate because I had traces from other prints on the bed and I tried to see if I could get rid of them.
Well they are still there and this happened.
So that process is correct, but did you mean dish soap as opposed to dishwasher liquid? It should be the dish soap with no additives. Also try not to touch the print area while you’re washing it. It’s ok to scrub hard as long as the scrubber isn’t made of anything abrasive. I would definitely try to scrub it again and try to get the rid of all the traces of previous prints.
