Thanks everyone! Problem solved. I'm now convinced it had nothing to do with cura settings. It was a "hardware" problem. I didn't have the Bowden Tube installed all the way into the hot end and the extrusion material was bowed through the nozzle and not entering the hot end in a proper way. When I accidentally discovered this, I pushed it all the way in, re-fed the material and now it's working flawlessly at all original settings. Still, I'll be sure to play around with initial layer width and flow settings just because it's interesting to see what effect those have. I'm very thankful for the comments and help - the lesson learned is that making sure all the basics are covered before blaming the software. Things like, is my printer plugged in? Is the bed level etc etc Thx!

I am currently playing around with line width and flow -also I'll reset the buildplate a little closer to the nozzle (more resistance against the paper) and see if that helps. I also did a test of line width set to 200 and got a slightly better result though. a I'll also change the brim to a skirt so it's a little clear about the continuity between the skirt and the actual model - I see your point about the model being perfectly flat on the buildplate I'm convinced that it IS on the buildplate and is not an overhang issue - I'll ignore the misleading red and assume cura knows what it's doing 🙂 After I make those changes I'll take images and repost - hopefully with settings that solve the problem. - Thx Framar!

Thx for the response Framar. I've included a picture of Layer one and only part (just over half) of layer two. Blue number one represents the very first layer - the fans were not running. Yellow number two represents Layer two which began on the left side on a crosshatch pattern and that is when the fans started to spin. I aborted so I could take this image of first and partial second layer. the first layers are terrible and so you can see why I'm assuming there is some sort of over hang issue at the buildplate. I'm including machine settings also just in case there is some issue there: I'm also printing this with 1.75 mm plastic on .06mm Extra fine setting with 20% fill. I'm also including image of the top of the print for reference so you can see all the layers above the first two are great . I have leveled the bed to be sure and turned off the option to generate support. So if it's not support that is being printed at the buildplate - what is causing the poor printing of the first couple layers?

I have also attemted to update the firmware on my ultimaker 2 - it is now version 3.3.0

I've included picture. After I installed the newest version of Cura (4.4.1) I now get an overhang at the bottom layer where it should be flat with the build-plate. This has never been an issue until I just today installed the newest version. I assumed the print would automatically touch the buildplate - Is there a trick to getting this back the way it used to be? I also tried an earlier version of cura and got the same problem. The first few layers are printing support material - it looks terrible. You can also see from the second image that I have "Automatically drop models to the build plate" checked. You can see from the image that I'm testing this out by printing some flat plates - I've searched the forums but have not been able to find an answer to this specific problem. None of the posts related to this had any resolution that applied to my specific problem. I'm printing with an Ultimaker 2 Thanks for any help - I appreciate it very much!

Update: As a test I installed a prior version and unfortunately the overhang on the bottom layer persists. grrrr

I'm pleased to report the problem is simply a loose set screw on the y-axis pulley. yep that's basically it. I've got the side panel off and I've tightened it but now I need to readjust it because the pulley is not aligned just right. Just thought y'all should know I think we got it. Thanks for your input and efforts....I really appreciate it!

Here is some video showing the print fail and another one showing my ability to move the y-axis manually. youtube video showing the print fail: https://www.youtube.com/watch?v=gaMOht6i-Vw youtube video showing manual movement of y-axis https://www.youtube.com/watch?v=EoOTnk1ratQ

I am using an ultimaker 2. I have tried to move the Y-axis manually and do not feel any obvious resistance or obstruction. I have never serviced the machine in any significant way, so no taking things apart which may have potentially caused a problem. I had a perfect print, and then on the next print the print began to skew towards the back of the machine along the Y-axis and then finally after a couple more tries the machine begins the print job at the far back of the machine on the Y-axis. I'll try and figure out how to post a video

Hello? Anyone?

Hello everyone! While working on creating a gimbal for a working mad eye moody eye for halloween I had some trouble with my UM2. I was able to print the first part of the gimbal mechanism but when I tried printing the second it appeared as if the Y-Axis was not moving smoothly over the bar. Several attempts later and it got worse and worse to the point where it seemed to lose track of the print head. I lubricated the bar and experimented and it apears that the X-axis is fine but y-axis struggles to move. I'm not sure if it's a motor issue or not. It has trouble getting to home position and can only move an inch or two when the print starts up - it's supposed to begin the extrusion at lower left of x/y position but it hardly moves but then begins the print at the wrong part of the build plate - far too close to the back wall of the printer. It then gets worse and worse until it's finally trying to print right at the back wall. Can anyone give advice for what is wrong with Y-axis and how to fix?
