@WilcoE said in quality issues with Ender 3 and Duet Wifi:
Thats the thing with extruder multiplier?
Yes, done and now using flow of 93% but still my dimensions are way off when using the default steps.
The prints are now really better only the dimensions are not good.
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE Maybe you are overextruding. Have you (re)calibrated esteps and have you calibrated flow?
Other thing: how are you measuring? If you don't have sharp corners, you are also measuring the corner bulge. Measure halfway on the sides.
Meassure the smallest value, try to avoid the bulge on corners.
My e steps are calibrated but did not calibrate the flow. Thats the thing with extruder multiplier?
@dc42 said in quality issues with Ender 3 and Duet Wifi:
How far out are the dimensions - what are the measured and expected values?
i'm using this calibration cube
https://www.thingiverse.com/thing:1278865
And my dimensions are:
y: 20.38
x: 20.28
z: 19.56 but thats because of z offset. Got a bed adhesion problem will fix that later
i'm not sure if my dimensions are wrong. But when checking things out on forums and youtube video everyone talks about calibration cubes and steps.
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE If the cube is out of dimension, and e steps are correct, you should calibrate flow. Don't change x,y,z steps.
Hi bartolomeus,
The quality of the print is now better, but the dimension's are not correct.
How can i fix this? The steps are still 80 for y and x and 400 for z.
Thanks!
Results with lower temp is the same only less shiny
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE great! Which temp did you use? The print is very shiny, looks like you printed fairly hot
yes, i like it 
210.. going try it with 195 just to test what the results are
Well... the print is much better.
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
Not 480, but 30000 is too high. Maybe start with 600 or so for the bmg clone. Actually I don't know the recommend jerk setting for BMG but 30000 is too high.
Ok, see on the forum some topics and i will try E2000
Again thanks for your help!
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
E30000?
Yes, that was also in my first config post.
Should i change that also to 480?
@dc42 said in quality issues with Ender 3 and Duet Wifi:
How does that compare with the one produced by the other printer? Are they both printed using the same slicer and slicer settings? Do both printers have exactly the same part cooling?
Yes, same slicer and also same gcode.
Both printers have exaclty the same part cooling
All printers are stock but, my printer is:
Ender 3
Duet Wifi
BLTouch
BMG Clone Extruder
And the printer of my friend is:
Ender 3 Pro
SKR 1.3 Board
BLTouch
i realigned my z axis and I loosened my Y belt and fixed again.
now printing with my Ender 3 printer and the same PLA filement color blue.
Also saw that my M566 jerk settings where not in my config anymore. So changed it back to: M566 X480 Y480 Z100 E30000
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE To me it looks like an improvement. Hard to tell, beacause the other pic is very small.
Other thing I noticed, is your motor currents a pretty low. I think tou can safely try 800-1000ma. The motors are rated for 1.5a, so 1a should still be on the safe side.
How is the printer mechanically:
- belts tight?
- Z-axis running smoothly up and down?
Belts are tight maybe to tight? got also here the other printer with the SKR and the belts from that machine looks not so tight.
z-axis running smooth, it's easy to get it up and down by hand
Going to change motor currents to 800ma
Here is the latest print.
Guys,
Thanks all for the answers and other information.
My latest print with extruder steps on 415, jerk settings lower and y and z steps to 80
Result is almost the same. Not much diffent
Changed now the thermistor settings and also did a temp calibration.
Now printing a new train, will post picture within 2 hours
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE hier ook
haha, post morgen weer
Will post tomorrow more info and pictures from process

@WilcoE said in quality issues with Ender 3 and Duet Wifi:
@bartolomeus Got a BMG Clone extruder.. when i do a steps calibration 530 it's the numer what it takes to get 100 MM filement out of it. If i ask for 100 MM
The steps for z and y are changed to get a calibration cube of almost 20x20x20
Did you calibrate the extruder with or without the hotend connected?
With hotend connected. Measured the filament which goes in
@bartolomeus ok thanks for fast answers, will make some test prints. Need some time for that, it's here already midnight
@bartolomeus said in quality issues with Ender 3 and Duet Wifi:
@WilcoE If the cube is out of dimension, and e steps are correct, you should calibrate flow. Don't change x,y,z steps.
Your bmg is a clone, is the Duet a clone as well?
No thats a genuine Duet Board.
@bartolomeus ok, changed jerk settings and the y and z steps

@fcwilt i know it's not a issue with Duet Wifi.. but i need some help Yes, all prints are the same PLA with 200 degrees C only other color. My whole config is located on my Github page
