Fadal work coords & home settings

[Neal]

Morning everyone--
Just to clarify the issue here, in Format 1 the machine will always return to the last set home position at the end of the program. Therefore, in order to get the table to the door the easiest way is to set the home position in Y at position you want the table to go to. Then take all of your fixture offsets from that point.
In format 2, the table will stay any place that you leave it at the end of the program. Simply program the table position you want and forget it.

All axis will move to this position when you send the axis home in your programs, or home the axis at the controller. When you go to the home position via the controller you will have 2 choices, go to home position or power off. You will use the first choice. All of your fixture offsets will be relative to wherever home position is, so if you reset home to a new place you need to pick up your offsets again. Before you shut down for the night send the machine to the power off (cold start) position. Choice #2 above. Whenever you do a cold start you will have a choice to move to the last home position. If you have fixture offsets set here then yes, the machine must go to this position. See above.

This is what I do, works great. I have my "home" set at X0.0 Y- 19.900. (4020 machine)

Understand that this position is E0 (not machine home / cold start position) and you can makes calls to that position in a program just like you can make calls to H0 (Z home or tool change position) independant of Ex or Hx.
