Is G43 modal? It seems that if I execute an M6 T2 command the length
offset is not applied unless I include a g43 for each M6 Tx commmand.
Is this normal? Or should I be able to initialize with a g43 and then
have all offsets be applied when the toolchange is made?

I know it seems inconvenient but a bit of background might justify it.
M6 Tx is not actually a command but two.
T6 says get ready to use Tool x. This could be done half an hour
before it is needed and with a big tool changer this lookahead is
M6 says change to the tool selected by a previous Tx
G43 Hyy says apply the offsets of the entry number yy in the tool
yy does not have to be the same as xx although it often is and can
thus be omitted. However at the time of the T word or the time of the
M6 the control does not know what G43 is going to be issued.
The three stages seem cumbersome when doing it by hand but do have
logic in them.
- John, thanks for the great (and quick) answer. The logic makes sense.
Actually seems more convenient to have control of all the steps. Every
day the picture gets a little clearer.
