I don't use G52, but from my understanding it is a shift from the current work offset.
So unless you are going to set the work offset at your camera point, I'm not sure this will do what you want.
If you want to just move the router when you are at your camera point... you can use the mdi execute command with this code:
mc.mcMdiExecute(inst, "G91 G00 X2.00 Y2.00)
mc.mcMdiExecute(inst, "G90")
G91 is incremental... it is also modal. Be sure to have the G90 line after your move to put it back into absolute instead of keeping it in incremental or you'll really get messed up.
