GCode preview does not follow Z coordinate in a G2 code.

Fri Oct 16, 2020 11:47 am

The following GCode file should produce a 360-degree spiral, and when run on my Duet-controlled machine, it does indeed take this path, but when the file is previewed in Simplify 3D it shows a planar circle.

It looks like the Z coordinate of the G2 command is being ignored.

Code: Select all

G90 ; Positions absolute
G21 ; Units mm
M82 ; Extruder absolute
T0  ; Tool zero
G0 X100 Y0 Z50 F200 
G2 I-100.0 J0.000000 X100 Y0 Z100 E5
Version 4.1.2

Does S3D support G2/G3 in preview mode? The arc generation was removed in v2.0 over 6 years ago, it would be
a bit surprising to see the implementation to preview them correctly would have evolved since then...

G2 preview works perfectly but it ignores the Z component.
