Hi, I’m struggling a little to dial in my PLA / Prints. The prints are warping at the corners a little and ideally I would like this not to happen for accuracy. I’ll describe what I have done.
PLA Generic Setting default, ran both manual calibrations. K value was updated with minor change.
PLA is POLYLite Matte
1st print warping
2nd print - 10% Rectilinear infill / Brim added with 5 and .1 - warping still happening
3rd print - 5% Rectilinear infill / Brim added with 5 and .0 / Cooling fan reduced from default 70% -50% / Bed temperature 60 Deg from default 65 Deg - warping still happening
4th print - washed texture plate with soap water and green scotch pad. Elmer Glue stick and returned all setttings to default PLA generic. The was the best print but still minor warping lifting in the corners. I also increased flow ratio from 95% to 96% as I was seeing signs of underextrustion on first layer but the print now shows what looks likes over extrusion final layer
Pictures attached of the final print. you can see the corners are pulling.
Any help would be greatly appreciated. Maybe I should order some bambu brand filament and try that. Should I be using a smooth plate ?
1st Clean your bed with soap and water. Hard corners are notorious for this issue. Some people I know use mouse ears under the corners to give them more surface area.
Could also be a cooling issue if the fans are kicking on to early and causing the layer above to cool to fast. As plastic cools it will shrink this can create stress on the lower layer. Stop Using Brims, Do This Instead

yes they are designed flat. the piece behind is lifting too. It lifting happens when the top layers are starting on the short one, the one behind started a while later.
I did all the appropriate cleaning with water soap. I also applied glue stick. still the same issue.
I have since tried the smooth cool plate along with glue stick. I started a fresh roll of Bambu Matte filament instead of the original other brand listed above.
The result was an improvement but not perfect as in no lifting.
I’ve had the same issues, especially with BL Matte and PolyTerra Matte (BL is worse, but PolyTerra wants to warp too)
Washing thoroughly with dish with soap helps.
Brims help.
But, the best was switching to a high-temp smooth plate. Wham Bam PEX in my case, but the BL high-temp PEI should work just as well. I don’t need brims on the high-temp smooth plates.
The cool plate, IMO, is a questionable value for the A1. Cool plates are designed to keep chamber temperatures down in enclosed printers like the X1. Not an issue with open printers.
Since switching to a high-temp smooth plate, the only time I had a warp issue was when I got lazy and didn’t clean the plate for too many prints. I print 70%+ with matte PLA.
thank you that’s some great info on the plates and could very well be my last mile solution to keep the warping at bay. I really like Matte pla and hope to continue using it.
Did you find you needed any particular printing setting with Matte PLA to help with a nice top surface. I’m also currently calibrating in the asthetic detail. Thank again
