<p>Despite the picture being a bit small and blurry, it is quite obvious that something is off. A better picture might help closing in on the problem with more precision.</p>

<p>From what I can see it could be wrong extrusion settings. I'm making a wild guess based on personal experience that the printer is over extruding way too much. I had similar looking parts a few years back after a firmware update. I simply forgot to update the steps/mm for the extruder. </p>

<p>Any recent firmware or hardware updates? 
From your explanation I understand you changed the drivers. Maybe an issue based on microstepping? (The corner looks like the nozzle was realy in the material while printing.)</p>

<p>I'm trying to troubleshoot an issue with my 3D printer (Robo 3D R1+). It cannot print vertical walls well any more. Here is a picture of what it looks like:</p>

<p><a href="https://i.sstatic.net/4Y4PE.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/4Y4PE.jpg" alt="enter image description here"></a></p>

<p>The walls are very inconsistent. To correct this issue, I've tried:</p>

<ul>
<li>Changing the nozzle</li>
<li>Tightening the hotend (to remove wobble)</li>
<li>Dehydrating the filament</li>
<li>Using brand new (good quality) filament</li>
<li>Printing faster &amp; slower</li>
<li>Printing hotter &amp; cooler</li>
<li>Trying different slicers (Ultimaker Cura &amp; Simplify3D)</li>
<li>Putting on a belt tightener</li>
</ul>

<p>The 5 motor drivers are all new as well, but this was already happening before I changed them.</p>

Check for play/loose nuts of the X-Z carriage/assembly.

Could be inconsistent Z movement. Get calipers, measure how much the Z moves when directed to move 100 mm. Let us know.

What layer size are you printing?

Isn't it Z wobble? Do you have the same effect on different parts? ( I mean, check if the same fatten/tighten patterns appear on the same height on different models).

It looks to me like you might be over-extruding. Have you calibrated the extruder?
