I have 2 motors for y axis and so i have the a axis slaved to the y.  I noticed in the config-motor tuning that the y axis motor movement profile is differant from the a.  Should they be the same?  I have a cnc mogul machine.

Thanks

they should be the same if they are the same to be safe take them of and make sure they are going in the correct direction as well. have you asked the cnc mogul people about it
