N1520 G02 X-17.5 Y10 I0 J9.5
N1530 G00 Z5

N1540 G92 X110 T1 (dia 10mm)
N1550 G01 Y127 X-11.5

So at N1540, the x-coord of the current tool position had been set to
x=110, which means that the program zero is 110 units to the left of
the current tool position.

So N1550 should send the tool to x=-11.5, that is, 110+11.5=122.5
units to the left!

The simulation shows the tool moving approx. 100 units to the right
instead!

Is there another interpretation of G92?

Anyone else using cncsimulator?
