Can't print the skirt properly
Hi Everyone
I have a Creality3D Ender-4 that I've had quite a few problems with but I thought I'd ask about the problems I've been having just getting it to print the skirt of the object I'm trying to print. Here's a picture of what it does:

Thoughts? I'm all out of ideas.
Thanks

Slow the Print Speed down for the First layer.
I print At 32% or about 3.6mm^3 Per Sec on the First layer, then using "Change At Z" I change the Print speed back to my normal 86% or about 8.3mm^3 Per Sec.
The first layer is the most important layer and should adhere to the bed, and I normally print this layer slower than the other layers to get the best adhesion possible.
My setting may be to fast for some 3D Printers though you understand where I am going with this.

I posted a reply here with images shortly after yours (Roberts_Clif) and it said it needed to be approved by a moderator. At this point I'm not sure if it will show up anytime soon, so I hope one without images will work. Your solution made my prints much better, and I have several successful and usable prints now! Still a few problems like the nozzle rubbing/grinding against already printed material, seams, spaghetti, and "boogers."
I want to thank you so much for getting me off the ground! I had been banging my head against the wall for a long time.

This could be caused by Z_Axis not moving the correct distance,
This could be caused by not enough Stepper motor current to the Z-Axis Stepper motor.
Or
It Could be because the Z-Axis is incorrectly adjusted.
(The lead-screw could be binding / Tension on the wheels could too High causing drag)
Post your slicer and slicer settings this may helpLast edited by Roberts_Clif; 09-04-2018 at 08:38 PM.

Hi Again
I'm using cura for everything, and I use a piece of printer paper to level my bed (adjust until the paper doesn't drag against the nozzle).
Settings in attached (zipped) PDF.

I am a little lower where you can just feel the drag of the paper under the nozzle.
.3 Layer Thickness
.8 top/Bottom Thickness (Should be a multiple of .3 so I would change to .6 or .9)
.04 Infill overlap (I would suggest .15 - as actual layer width is about .48)
Retraction Distance 4.5 Retraction retract Speed 20mm/s
Z-Hop height mine is .075 ~ .1
Fan Speed 50%
I use Cura 15.04.6 Most of the time though have printed many with the new Cura 3.xx.x.
I like the feature where you can print the two surface walls at .14 and the a single Infill at .28 or print three surface walls at .1 and then a single at .3
(Truly speeds up print time on a fine surface model)

Thanks for the tips
I entered your settings and printed 3D benchy at .3 layer thickness. I attached some images of how it came out. What do you think?
Thanks

Not looking shabby!
Now you should be a a good postilion to Print a Temperature Tower.
I would add a parts cooling fan you will surprised how well they work at eliminating the fuzz.

OK,
So I tried to print the temperature tower, but if I print the STL it doesn't print at the right temperatures and when I printed the gcode the filament got jammed. I'll probably get the fans too.
I tried printing a calibration cube, but I noticed that the cube was skewed - it had 2 sides that were square and 2 that weren't (horizontally). Pic attached. It's about .5 to .6mm off, and it's enough so that when I try to print a lego it won't mate with a real lego. I don't know how I could correct this by adjusting steps per mm.
