Tool changer actuator endstop.

Perhaps what I don't understand is how the cofig knows which endsop goes with which drive.

Using M584 to map drivers to axes does not affect endstop inputs. Endstop inputs XYZ are pre-allocated, after that they are allocated in the order in which axes are created. So if you create just one extra axes (e.g. U), it will use the E0 endstop input. If more than one axis is created in a single M584 command, endstop inputs are allocated to the new axes in that command in the order UVWABC.
In RRF3 the endstops are definable.

UPDATE
Not sure what is going on but after a few days of taking a break I decided to get back to working on this and now the U endstop works!
My config is still exactly the same as it was above.. so confused.. anyway now on to the next issue! 
-
if you didn't change the config, odds are the wiring is not 100%.

@cdl1701yahoo-com RepRapFirmware also creates endstops for defined tools, of which you have two. So your endstops as reported by DWC are X=0 (connected to X_STOP), Y=1 (connected to Y_STOP), Z=2 (connected to Z_STOP), U=3 (connected to E0_STOP, the next physical connection available), T0=4 and T1=5 (both not defined/connected).
I agree with @bearer, probably dodgy U endstop wiring!

There needs to be a banging head against the wall emoji. So I have been fine tuning everything tonight and getting my tool offsets set up when all of a sudden this endstop problem pops up again. The endstop says that it is triggered but isn't so when I try to use the tool lock it thinks it is already at the endstop. Even when I replace the endstop with a new one it does the same thing...!!! -
Was the wiring replaced as well? Does the wiring run alongside other wiring?
-
@cdl1701yahoo-com Can you Post a picture of your setup? Maybe it is a mechanical or wiring problem...
-
Turned the machine on and it is working again...
@droftarts Yes, I have a test endstop that I use that has its own wire and I can activate it manually with my hand. That one works fine for the X & Y but not on any of the Estops. This printer does some strange things sometimes just randomly so I am wondering if it is the board.. it is quite old and has who knows how many hours of run time on it.@Phaedrux it runs seperate from any of the high voltage wires and the stepper wires so I would not think that it would be getting interference but I guess it is possible?
Anyway, it is working for now again so back to fine tuning.

I’m still using one of the white PCB beta Duet WiFi boards! However, it didn’t get much use, until I installed it this summer on an old printer to run as a testbed. Tony told me there aren’t many left, as most were tested to destruction!

This one I think is about 3-4 year old and has been running since then but it is not a white one. I do have some stepper motor cables that run over the top of the board, I an thinking tomorrow that I will re-route those to have them go around the board rather than over it and see if that helps.
So far though has been running all day with no issues.
