Keep my Z height the same but it prints different consistencies at different spots. Is the bed un-level? Maybe a clog or bad filament outflow?

Hey all, 

I am just trying to print your typical 1 layer square to get a perfect Z height. I am using Petg. But I notice at the first part of the square where the printer starts it is a way different consistency than when it ends. Even when I do not touch the Z height at all.

The bottom right is super stringy and then once it gets about 1/4 to 1/2 of the way through it starts overlapping and creating ridges like it is too close to the board. Everything seems flat and perfect and as far as I can tell the mesh bed leveling is doing fine. I check the board and it is good on bottom nothing pushing it up. One thing I notice is on the Test line before the print it comes out weird like stringy with knots in it. Is this a sign of a clogged nozzle? I did a cold pull specifically to try and fix this and it looks like its clean in there but still continues. 

I hear there were issues with clogs on the mini as far as you can tell does this seem like a clog issue or an uneven bed issue? Or maybe my tip is not even? I am out of ideas at this point. This whole time I thought it was me doing the Z height wrong. But even when not touching the Z at all the consistencies change so much from start to finish so I know it isn't me. 

In this picture you can kind of see how it is stringy then solid but almost overlapping with ridges towards the end.

Too low?

It is hard to tell since you removed it from the bed.  I think it might be too low.

Did you make First layer calibration successfully? And before all: make sure print sheet is perfectly clean.

Odd

One side looks too low and other too high.  

Try cleaning the bed with dish soap and water and raising the bed just a tad.

Check your bed leveling

Hey,

I wouldn't say that it has anything to do with cleaning the bed. Even if it's not cleaned, the layers would still be squished into each other. 
If this problem is reproducible, I'd say it has to do with your bed leveling / mechanical set up. 

Did you just assemble the printer? Kinda feels like it, because your account is new and you are printing first layer calibration prints 😀

I assembled a Mini today and noticed that the X-Axis wasn't squared up at all with the bed. In that case, the bed leveling might not work properly. I think that's one of the biggest flaws the Mini has mechanically, lining up the X-Axis in all freedoms of rotation. 

Hook your printer up to Pronterface or a similar terminal. Run a G28 (Homing procedure) and a G29 afterwards. Copy the result to the following website: " https://bbbenji.github.io/PMSBLM/ "  and please attach the outcome in your next message.
