Re: Help with transfer - Macturn250W OSP200
You've got a timing issue of when the W move is occurring. Depending on parameter settings, your G140 and M01's can work like P-codes, so with the M01 it may not be reading ahead as much as with it off. Check the timing in your program with single block on to see more closely when the alarm happens. I think you'll see that it's reading different areas of the program timing wise with M01 on vs off. You don't show enough code for both turrets for us to properly evaluate.
On the LT-300 (very similar) I also was using the G145 command to switch to W-positioning mode before doing the transfer and G144 to turn it back off.

Experience is what you get just after you needed it.
