Help with tandem axis Y

Thank you Tommy and Djdelorie, i appreciate your help so far, i had a few minutes and disconnected probe and assign individual pins and did not work but i did not have much time and I will be away form the shop probably till Tuesday (which sucks because i want to convert this machine so bad) but i like the idea of only using 2 pins this way ill end up opening one output. and ill get back here to report how ever i did not find the option of assigning multiple stepgens to one pin so i assume it will have to be done in .hal and .ini??!! ill include those once i try (if i get a chance ill sneak in the shop on Sunday (fiancé permitting lol)

thank you again for the help
