Up on top of the ATC is a motor that drives the cam. Take the cover box off, and you should see a "bail" (looks like a paint can handle, maybe?). Lift the bail to release the ATC brake, and you should be able to spin the fan to move the arm back to it's home position. Don't forget to apply the brake again after you're done.
There is a few ways that you can do that. If the MTB used a system variable to track the tool in the spindle then you can use it in the macro. If they did not then you can set a common variable up to do the same thing. I cut the program that I posted for you in the other forum.
Now if the MTB does not have a system variable we are going to use variable #500. Make sure that your machine does not use this variable for anything. If it does select another variable to use. Just make sure that it is 500 or above because these are the permanent common variables so they hold their value even if the power is turned off. First manually set #500 to what the current tool is in the spindle thru MDI mode.
O9020(TOOL CHANGE PROGRAM)
IF[#500EQ#4120]GOTO1—(checks to see if current tool is set to tool being called jumps to N1 if it is the same tool)
#3=#4003—(sets #3 equal to modal G90 or G91)
G40G80—(tool dia cancel & canned cycle cancel)
G91G28Z0M9—(tool change position in Z & coolant off)
G28Y0M5—(tool change position in Y & spindle stop)
T#4120—(calls modal T)
M6—(tool call of modal T value)
G#3—(reinstates previous G90 or G91)
#500=#4120—(sets #500 to the tool that was just input into the spindle)N1
M99--(sup program end)
This should work for you if you have macroB programming in the control.
Jerry you need to post it as a full topic either in Fanuc or Daewoo/Doosan
What State is the machine in
Has it been or can it be referenced yet ?
Do you have any manuals and what model of Control is it ?
