Re: [CAD_CAM_EDM_DRO] Re: Re: Emc -- program problems

I used the tutorial for text on circle on the vector site and here's
what happened.
EMC ini. settings--
Task controller section
task=minimilltask
cycletime=.020
interpreter section= rs274ngc
parameter file=emc.var

Vector NC section settings---
contour = &normal mode
cycle = 0
driver = incremental coordinates x,y,z
output G00,G01,G02,G03 modal
show only changed x coordinates
show only changed y coordinates
show only changed z coordinates
circular motion = incremental coordinates(I J (the rest of this line
went off the screen)
coordinate format = no plus sign
decimal digits 6
scale factor xyz-1
initial position x0 y0 z2
units = dialogdigits = 6

here's the return-
command(N16 X-0.030676 Y0.119846 Z0)called
execute return 0
read return 0
line return 8
command(N17 X-0.026933 Y-0.120741)called
execute return 0
read return 0
line return 9
command(N18 G02 X-0.063984 Y-0.030428 I-0.043921 J0.009797)called
ERROR- radius to end of ark differs from radius to start

Do you think there could be something wrong with my computer? Or maybe
my EMC settings?
