I'm trying to do a circular helix with toolcompansation.
the code is ( without z movemant)

G90 G40
G21
T03
G0 X0 Y-100
Z0
D3G41
G01 X0Y-76 F800
G02 X0 Y-76 I0 J76
G01 G40 Y-100
M02

But i get a error message that i cant do concave radius with toolcomansation!?
I can run the code if i set the tool diameter to 0. But not with tooldiameter set to 10.
The circle is 152 mm in diameter

Any sugestions?
