Hello I have an m39 Ajax control on a Bridgeport Boss mill and want to know if its possible when using single block mode to try a program out and when you then press F5 to let it go fully auto, can you get it back into single block mode. I ask this because sometimes when running through a multiple part program you get to the second part and I want to be able to return to single block mode but it doesn't seem possible, am I missing something in the origonal set up of the control. Thanks Colin
