Printing problems in the latest layers
Hello, I am confronted with a problem only on the very wide parts, the part below is 220x140 mm and 10mm thick, it is a part for a CNC. The filament is the Prusament Black Jet. My print settings are also attached. With smaller pieces, my prints are impeccable. Do you have an idea where it comes from.
THANKS
RE:
Considering it's in the around the corners of the piece, do they look like they lifted from the bed? Like they were not stuck properly?
RE: Printing problems in the latest layers
No, the piece is always well stuck after the end of the printing, and the corners too, if we look at the photo, we see the same thing on the bottom throughout the piece.
Warping like that usually lifts the corners off the sheet, sometimes it lifts the sheet from the bed ... show us the underside of the print. Make sure you are not printing in a draft or other source of cold air.
Cheerio,
RE: Printing problems in the latest layers
I don't have a warping, after printing, I put my piece on a mirror, and it is very flat. I print on the table of my living room for the moment. The temperature must be 22 ° Celsius (71.6 ° Farenheit). Maybe it's too low for a print of 4:30 am. I put a photo below the first layer (below).
RE: Printing problems in the latest layers
I print with My mk3.9, in a shed, where it is very cold, so your living room should not be an issue
Is the first picture, your first layer?
Sometimes my first layer, is not as smooth as I Would like, If this is the case I raise the Z axis a little....
(This does not work on a mk3 series printer) During the first layer, on the Mk3.9 and mk4, you can press the LCD Knob, to access the Live Z menu
If your first layer is going wrinkly, try raising the live Z a little (More positive number) say Z = +0.100 and see if your first layer improves
this is an unusual poor first layer on my printer,
The first layer is too low causing ripples instead of a smooth layer
Unfortunately this happened the day before I went into hospital, so I have not had time to find out what went wrong.
I was able to reprint the model I was working on, by adjusting the Z height higher
(they won't let me have the printer with me in hospital...)
If this is your last layer, and your extrusion multiplyer is set to '1' lowering the Flow rate while printing by say 5% may help
an extrusion multiplyer greater than 1 can cause ripples on top layers
