I'm replaceing a spindle on the bridgeport. what I want to know is there a way to check the spindle line up with the tool change prior to Install

Two different things to check the alginment of spindle to tool change height.

1.) M19 does spindle orient Does it line up with the arm correctly? Parameter 4077 is the value that controls this position.

2.) z-axis height to tool change position. "G30 P1" The parameter for this position is 1241 "2nd reference" This value is a direct position of the z axis in MM.

What I would do is preform one of these codes through MDI then go up on top of the machine and crank the tool arm's motor manually with a 12 MM socket wrench. Pull the brake lever away from where it was before cranking. This is a mechanicl brake release. Crank the bolt counter clockwise to go towards the spindle and vise versa. Crank it till it goes to the tool grab position (60 degrees). Then check the position of the arm to the spindle. Arm must go back to home (0 degrees) before you can move/program machine. Keep adjusting those parameters untill it lines up.... good luck my man!
