I have been using Sunlu filament (because Bambu has been out of stock with spools) on new X1C and for the most part, no issues. But this simple print is really turning out bad.
Sunlu Basic PLA - 210°
PEI Textured Plate - 65°
All other settings default Generic PLA
Standard print @.2mm
After taking a picture I saw the layer adhesion seems really bad. I couldn’t see it from a distance. Do you folks have any advice? This is a hobby, not a business. Keeps a guy near retirement busy.
I think it looks like wet filament, even though PLA is not terribly hygroscopic, and I do get tired of saying it’s wet filament.
Dry filament is such a basic requirement that we should never have to ask if the filament is dry. It is liking asking if a car that will not start has gas.
While I’m ranting a bit, for the sake of all that’s holy and the well-being of your nozzle, avoid grid infill, especially on such a large print. The nozzle path crosses itself at the same height on every layer at every intersection. On a small print the first line laid down might still be soft and the nozzle can cut right through. On large prints, that line has had time to cool and the nozzle will be hitting a hard line of plastic. How can you expect the nozzle to lay down a smooth line if it just bounced over a curb?
If you like little boxes, use rectilinear instead. Gyroid infill would be stronger, and seems to help prevent warping. Or use any of the other non-crossing infill patterns.
If you print in “silent” mode (50% speed reduction) is the infill better?
Sometimes 3rd party filament doesn’t flow as well and will struggle when printing infill (normally the fastest part of printing). Bumping up the temperature 5-10c can help if this is the case or slowing down the infill printing speed.
Also keep and eye on the nozzle thermal paste as it will dry out and you will have issues printing fast because of the reduced heat transfer.
