Under extrusion

[torn wharf]

Machine: Cr10s
Slicer: Cura
Material: PLA (Overture)
Settings: Nozzle 220°, Bed 60°, Layer height 1.2mm, Infill 20%, Print speed 50mm/s, retraction and Zhop enabled, No support, No additional build plate adhesion.
Issue: I am consistently receiving severe under extrusion.

My printer was performing well for many prints prior, however this issue has stumped me. I have replaced both the extruder and entire hot end components, and am still having this issue. Any and all advice will be taken and appreciated.

Attached is a photo of the result.

please attach the gcode

my first guess is that your extruder isn't gripping the filament properly, but let's see what the gcode looks like

[somber shuttle]

your first layer is close to the bed so it causes your extruder to warp I guess

I have cr10 smart, I had this issue before

The plastic extruder cracks at a bad use

does your extruder ticks like a clock at first layers?

if yes, check your bed leveling once and raise the nozzle

if it still keeps going, check your extruder and nozzle again

sometimes clogged nozzle can cause that too

if nylon tube has a gap between heatblock, that may cause too

I apologize for the late response, but how do I do that? I attempt to attach it to a message, however discord tells me there is an issue and nothing more.

[torn wharf]

I have personally not herd any ticking while the print is running, which is partly what's adding to my confusion to this situation. I will go ahead and recheck for filament buildup around the heat block.

[smoky flame]

is the extruder gripping the filament properly? how much force is required for you to pull the filament from the extruder gears?

try restarting discord/pc? or upload the gcode somewhere else and provide the link

[torn wharf]

The Gcode is evidently too much to upload without discord nitro. I have found a roundabout solution, but if you're not comfortable with this method I can find another. This link should lead to the Gcode download: https://filebin.net/quxti0ptkwdrj7rh

[smoky flame]

That's not a publicly available link

google "free file upload" and use one of the first 10 results

[torn wharf]

That's my mistake, I have replaced the original link with one that should hopefully work.

143MB 😐

it's fine. it's just. maybe get some simple prints working first. 😛

gcode seems fine. have you inspected your extruder tension?

[torn wharf]

I have just done so, and I feel that it is currently at the desired tension. I will be doing a quick test.

[torn wharf]

I have found a problem, if it's not the problem:

Would you say too much tension, too little, or is the gear not biting?

[smoky flame]

not enough. but it's a terribly designed extruder. consider buying a BMG clone. they are cheap enough and work well

[torn wharf]

What are your thoughts on creality branded metal upgrade/replacement for the extruder? That's what I had originally used when the issue started.

[smoky flame]

no. don't buy that. it's the same terrible design as the stock extruder.
