Getting The First Print Just Right
-
Ah, i've thought that this was Nylon but it's better as you confirmed it.
Alloy 910 is normally easy to print and you've no issues with the Layer Adhesion at all. It seems that either your Speed (Travel, Retraction, …) are to fast for that mechanic cause i can see shifting.
Have you tried to print a calibration cube before? Maybe also export your FFF-Profile and share it.
-
Have you tried calibrating the extruder? What are you steps/min set to?
-
Here is my FFF file. I also started the print again dropping speed from 58mm/s to 40mm/s and it already looks better. The holes still could use to rounder/clearer.
-
Here is the settings from [c]config.g[/c] for my drives:
[[language]] ; Drives M584 X0 Y1 Z2:4 E3 ; set Z to Z and E1 drivers M569 P0 S0 ; Drive 0 goes backwards M569 P1 S0 ; Drive 1 goes backwards M569 P2 S1 ; Drive 2 goes forwards M569 P3 S0 ; Drive 3 goes forwards M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation M92 X80 Y80 Z406.35 E1005 ; Set steps per mm M201 X800 Y800 Z100 E1000 ; Accelerations (mm/s^2) M203 X15000 Y15000 Z10000 E3600 ; Maximum speeds (mm/min) M566 X600 Y600 Z100 E20 ; Minimum speeds mm/minute M906 X800 Y800 Z800 E1400 I30 ; Set motor currents (mA) and motor idle factor in per cent M84 S30 ; Set idle timeout -
Did you proof if espacially your Extruder Motor really need 1400 mA of current? That seems very high for me. Additional i assume that you not need to set the Extrusion Multiplier to 1 cause for me it loóks as you have calibrated the steps correctly.
-
According to the specs from E3D, their Titan Extruder motor has a rated current per phase of 1.4A.
-
Drop it to 855mA and look what happens. Raise the Current only if you are notice mssing steps or if the torque is not enough.
How long is your bowden Setup?
-
Direct drive.
-
If this is a direct drive i'm wondering why you use 5mm retract in your configuration. In my Bowden-Setup with ED6 Chimera (aboutr 60cm each) i'm only using 1.20mm.
But the questions in regards to "calibration" of Steps are still not answered. Have you tried to print it in PLA or PETG instead to proof the Settings and Mechanics are working and maybe only the Filament is bad?
-
I stopped the print. It's a bit better w/ the slower speed. One thing is that for several layers, it wan't extruding properly.
-
I ran a 20mm cube. It came to X: 20.3, Y: 20.19, Z: 19.75. Not too shabby.
-
That does not indicate anything, cause "dimensions" impacts Steps of Axes and also Steps of the Extruder combined with Extrusion-Width. Therefore again: Have you ever calibrated your E-Steps/mm and have you tried to print the same with a different material?
-
I calibrated my extruder; marked off 120mm, extruded 100mm, and adjusted accordingly. As for printing in another material, that's why I'm printing the fan holder for my extruder. I also have some Taulman n-vent and In-PLA, but I believe both require a fan. Does NinjaFlex require a fan?
-
I have no part Fan currently and still be able to print most every thing without any issues. Okay, stringing will happen for sure and sometimes not a perfect finish. But never so "ugly" as yours.
-
Why thanks. Any other suggestions?
