E30000?
Yes, that was also in my first config post.
Should i change that also to 480? -

Should i change that also to 480?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! -
Well... the print is much better.

@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 -
Results with lower temp is the same only less shiny

@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!

How far out are the dimensions - what are the measured and expected values?

i'm using this calibration cube
https://www.thingiverse.com/thing:1278865And 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 lateri'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.

@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? -

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. -
print it a 50 or 200% scale and see if the error stays constant.

Hi,
I set my steps/mm by "jogging" the head from DWC and insuring that, say, a 100 mm move actually moves the nozzle tip a 100 mm, easily measured with a mm scale.
Then I print my calibration cubes and adjust the size, if needed, via M579.
