Hello there!
I just started printing and trying to print the driver case that is instructed in the K8200 tutorial. I did however notice that on layer one the printer seems to not extrude enought filament. I have the 3mm thick filament that I have bought which should be high quality. From what the settings tell me the printer thinks that it is indeed 3mm filament that it is using.
When printing the first layer seems very thin, and not very coherent. What I mean byt that is that the straight outer lines look more like dotted lines, as if the printer feeds to little filament.
What could be the problem? At first I thought that the printer did not have enough tension to pull in more filament, I have however seen to that it does. I’ll try printing the whole thing now and see what happens, I would however love some ideas of what might be wrong. If it is wrong that is. (I am saying this because the lines on the shown 3D model in Slicer seems a lot thicker and smoother. Whilst the actual print looks like dotted lines all over.
Here is a picture of what I mean: postimg.org/image/k1wj70sv3/
As you can clearly see here the outer lining has not even been made. This is what the print looks like after 3 minutes, whilst the actual model says it should look something like this: postimg.org/image/ay1p0vpmn/
Forgot to mention that it prints (from what I can tell) fine in manual control. Then there’s a constant fluent flow of filament.
Are you printing ABS or PLA?
What is the temp of the hot end?
Is the thermistor on the hotend properly mounted?

I am using PLA.
The Hot End? U mean the extruder? It is steadily on 190C* The bed is on 50C*
It is hugging the hotend and looks alike the instructions.
The PLA comea out fine in manual control, so from what I can see it’s not clogged. Something however is off, I am guessing a setting but I feel lost in the configuration, to me it seems fine?
What voltage did you set the stepper driver to?
The 0.425 suggested in the manual is too low.
Set all steppers to 0.55v instead. On 0.425V the motors are likely to loose steps.
If it did not work better for your extrusion problem, report back here.

Actually you are right! I just switched driver as the one I got originally was faulty. Thus I have not adjusted the voltage on the Extruders stepper driver! Thanks! Great idea!

I tried today and it did not work. I noticed that some filament was stuck in the extruder. I cleaned it out and fixed it. The same thing occured while printing though. I noticed that when it was printing all the melted filament got stuck on the nozzle, like a waterdrop accumilating more water, getting bigger. That’s why there was a dotted line, as the ball of filament got bigger it touched the heated bed, leaving traces. So now I am kinda stuck again. I am currently moving the homepoint of the Z axis closer to the heated bed. It does however seem odd to me.
In the future I’ll get a mirror so that the surface is completely flat, as of now the edges are lower than the middle, with that said it still does not print…

I now also tried pushing down filament whilst it was printing, it seemed to print a little better, there was however still not much filament coming out. I’ll let it print the whole print and see what happens this time.
Check the small gear.
Look for cracks and make sure the screw is tight.
