Settings for CPE


Recommended Posts

Posted · Settings for CPE

Hello everyone,
I recently printed Ultimaker CPE with the Generic CPE settings (240°C/85°C temperatures and 7% fan) and 0.8 mm nozzle and wall line thickness, 40 mm/s speed. I am more than dissatisfied with the result. The wall layer is perforated and leaky and when you press on it, the component looks slightly spongy, i.e. elastic, which is not even the case with PLA in the same component.

Can anyone kindly recommend pressure settings for the S5 that should give me very good results along with 0.8mm nozzle and 0.6mm layer height?

 

Thanks in advance!

    My first guess is, that you print too fast with your settings. 0.8 nozzle, 0.6mm layer height and 40mm/sec is too much. Try to print with 0.4 layer height if it gets better. 

     

    I think you see underextrusion because the heated nozzle is not able to melt that amount of filament in time.

    Hi Smithy, thanks for commenting.

    I have to use this layer hight because I want to test different materials. The other objects worked very well, so I habe to use 0,8 nozzle and 0,6 hight. Otherwise I have to print all object with 0,4 hight. I hope you unterstand the circumstances.

    But you think that 30 mm/s would work better?

     

    PS: The settings I chose were the Cura defaults.

    up the temperature will help some but if the layer height is just to big it won't help enough.

    Yes you can try to print slower, that should help.

    Additionally you can try to print hotter as dap mentioned but there is a physical limit how much material the print core is able to melt per sec.
