I keep getting the error - Radius to end of arc differs from raduius to start line ...

Using absolute I & J

When I go back in and check the difference it comes to less than 0.00001 (1/100,000) error, and is awfully hard to get rid of.

For instance -

startpoin to center radius -

X 1.1682 - I .5713 = .5969, squared = 0.35628961

Y 1,9091 - I.5713 = 1.453, squared = 2.111209

added together = 2.467499

square root = 1.570827365

End point to center radius -

X0.125 - I .5713 = -0.4463, squared = 0.199,183,69

Y1.9622 - I 0.4561 = 1.5061, squared = 2.268,337,21

added together = 2.467,520,9

square root = 1.570,834,46

Difference =

1.570,827,365 - 1.570,834,46 = -0.000,007,095,0

Add 0.0001 to any of the dimensions and the radius grows too much.

Any clues as to how to minimize this problem so Mach3 can tolerate this insignificant bit of error?

I am doing some "artsy" stuff that has many arc segments but have to deal with this only 2 or 3 times in a program.
