I am printing ABS in an enclosure and most of the prints have worked out well with minor tweaking. However, the top layer always seems to split or skip a step (not sure which).

split top layer

Layer was peeled of on previous prints

The cube is sliced in Ultimaker Cura 4.3.0. with 0.2 mm layer height, 0.4 mm nozzle, 80 °C bed on lexan and a 235 °C hotend.

The G-code to the calibration cube/chep'scalibration cube is attached: G-code.

While I'm on the subject of slicing and calibration my calibration angle is coming out as before in Simplify3d, this time the layers look great but the onion skinning within the print itself so I could actually separate the calibration angle like an onion.

    $\begingroup$ Can you test with the cubes scaled up and down by 10% to verify it's the top layer rather than layers at a certain Z-axis position? $\endgroup$ – Carl Witthoft Oct 31 '19 at 14:28
