Parts get loose from print bed
I am trying to print this camera mount on my printer but I have difficulties to get the nuts printed. They always get loose and it ends up in a big blob on the extruder. I am using Prusament PLA with the standard settings and this doesn´t seem like a very difficult part to print.
I am using a powder coated steel sheet and clean it with IPA 99% before every print. Attached you can see the result of my prints and also my first layer.
Small PLA parts might print better on a smooth sheet.
Some contaminants don't dissolve well in IPA. Try washing the steel-sheet with dishwashing detergent (Dawn/Fairy) and plenty of HOT water, rinse well and dry with a fresh paper towel. Handle by the edges only.
You say you have difficulties printing the nuts. Did you try other parts already?
In addition to cleaning the bed you should try adding a brim to give the parts more surface area.
I just tried another part and the same thing happened. It´s interesting, because when I pause after the first layer and poke it a little it seems to be very well attached to the plate.
But I haven´t actually tried to wash it with soap and hot water. I assumed using IPA would do the same job. So I´ll try this and see if anything changes.
Live Z - pictures look like the nozzle is dragging thru the printed layer. Too close is my take. Remember, textured sheet is THICKER than the smooth sheet - so you have to have a whole different game plan for your live Z. Brim will also help you with bed adhesion.
My game plan would be:
Switch to smooth plate
Thoroughly clean plate
Redo live Z
Use Layerneer bed weld
Ok thank you all! I managed to print the parts eventually. The key was indeed to adjust the Z height a little bit and also using a Brim. I don´t have a smooth plate yet but I consider buying one for these kind of issues.
Remember, textured sheet is THICKER than the smooth sheet
It is the other way round.
The PEI sticker on the smooth sheet is thicker than the powder coating.
I measured my Prusa sheets. Smooth is 1.2mm and textured is 0.75 mm
@Jo. Good to see you got it working.
Yes, textured is thinner
There are also other brands you can try. I’ve become fan of the BCZAMD textured sheet. Unlike the Prusa one, this one has worked great with every filament type I’ve thrown at it. A simple rub with IPA every now and then is all it needs
