Prints coming out terrible!!

Any suggestions on what I should do? I have the right size of filament in the slicer.


Thank you Nathan

Could you give more information, Speed models printed at, Temperature models printed at, Material Printed with.
Do you have a parts cooling fan, What speed is parts cooling fan set to.

I am not at home right now so I will do my best.

printing speed 60mm/s with PLA at 205 degree C. I have a parts cooling at 35%.

That looks like a lot of underextrusion. Are you sure the steps/mm for the extruder and the filament diameter are set correctly?

Filament is set to 1.75 mm. What should the steps/mm be set at?

This would depend on what kind of extruder setup you have.

1.75mm is the general diameter, but not neccesarily the actual diameter. You need to measure with calipers and calculate the factor to make up for slightly larger or smaller diameters.
The E Steps value is usualy set correctly in the firmware if you buy a complete printer. If you build it yourself or changed the extruder you need to calculate, and measure for control, how many steps it takes to push the filament 1mm. I usually calculate the intial value from the circumfenernce of the filament pulley and then measure over 1m of filament for fine tuning.

How would I calculate it? Is there a calculator to use? Thank You!

For the extruder start at step 4

I prefer This

It ended up being a clogged nozzle. Thank you for all your help.

Clogged Nozzles and Deformed PTFE throat liners are real common problems of under-extrusion. I have many nozzles and PTFE Lined throats in the parts bin.

This is why I ask for more information. When we see new users or users with few forum posts we assume.
With more information we could have seen that you had successfully 3D Printed, and could have given the other reasons why your nozzle could be under extruding.

Need more help, just post question?
