From the rest of your comments, and if I understand you correctly, the
program should read:

G1 X0.0 Y0.0 (gets you to the start position, could be G0)
G1 X2.0 Y2.0 W0.5 U0.5 (See note below)
G1 X3.0 Y4.3 W1.0 U1.0

A constant contouring control will produce a smooth, uninterrupted movement
on W and U.

Note: I'm assuming this is where W and U should be when you get to 2,2. If
not you need to calculate the correct W,U position. I'm probably wrong about
the intermediate W and U position, but I don't have a calculator that does
square roots at the moment (batteries are dead ;) ).

Sorry, you get to set each address (like G, X, W, M, etc.) once for each
block.
