ok -- thanks for this info -- i was able to see this error using a mm setup.
In the ini file:
[TRAJ]LINEAR_UNITS = mm
[DISPLAY]NGCGUI_PREAMBLE = mm_std.ngc
Added a tool table entry for tool 5 is:
T5 P5 D10 ;added 20140126
None of gcode in qpocket.ngc (nor in the helper subroutines
that it calls) know anything about mm or inches so i put some
debugging statements in interpreter files (diffs below)
and used a qpocket test case with a 60mm square pocket aligned
with the cartesian axes and a 10mm diameter tool:
o<qpocket> call
[5][1000][2][10][0.1][0.02][0.2][0][0][0][0][30][30][30][30][0][1][0][0][0][0.5][0.002][1][0]
msg: "Tool radius not less than arc radius with comp"
emc/rs274ngc/interp_arc.cc:119 arc_radius=5.000050 tool_radius=5.000000
ok
emc/rs274ngc/interp_convert.cc:695 A_ang=-1.570786 cos=0.000010
fabs(cos)=0.000010 TOLERANCE_EQUAL=0.000100
(fails -- .00001 not less than .0001 == TOLERANCE_EQUAL)
Similar error with iquad using a 30mm square:
o<iquad> call
[5][1][2][10][.1][.02][0.2][0][0][0][0][30][30][30][30][0][1][0][0][0][0]
msg: "Tool radius not less than arc radius with comp"
debug output:
emc/rs274ngc/interp_arc.cc:119 arc_radius=5.000500 tool_radius=5.000000
ok
emc/rs274ngc/interp_convert.cc:695 A_ang=-1.570696 cos=0.000100
fabs(cos)=0.000100 TOLERANCE_EQUAL=0.000100
(fails also)
The gode routines fudge the arc_radius so that it is bigger than
the actual tool_radius (tdelta). Note that a check in interp_arc.cc
comparing arc_radius and tool_radius succeeds.
A different test in interp_convert.cc fails comparing
a fabs(cos) result with the TOLERANCE_EQUAL set to .0001 in
interp_internal.hh
I'm not sure what modification is required for the failing test.
