Use single block
- look ahead cannot be bypassed when using cutter comp, as this is required to calculate compensated tool move positions relative to the programmed contour ( minimum look ahead is 4 lines of NC code )

Thanks. I am not using cutter comp. I need to do some calculation using variables (VC) and in auto mode (not single block) the calculation is done ahead of time. Immediately after I start the program the values of variables change to their final state..

Try this

VOPRB[2]=VOPRB[2] OR 128 (Sets NC Opt Para Bit No2. Bit7 to 1)

Code in here

VOPRB[2]=VOPRB[2] EOR 128 (Set NC Opt Para Bit No2. Bit7 to 0)

I think you can add 4 dummy blocks or use an M331 if I remember right. Don't have a book in front of me at the moment...depends on if it's a L or M though.

Best regards,
