Limit and Home switches


 

Hi
I have a 3 axis mill developed from a conventional Milldrill with ballscrews and drives added. All working and functioning correctly.

As is the home and -ve axis limits.
How can I use the home switch as a limit when in normal operation?
Or is there settings I have missed?
I tried adding the limit with same port and pin number. Howeve this works when running the G28 and stops the homeing from completing.

Thanks

Graham


 

I am using three limits here is the pins


 

Hi Terry,
N attacments?
Question is are you using the same switch for home and limit ?

I think if you are using one switch for home and the same switch for limit and you are using a smoothstepper.

then in the smoothstepper config under inputs if homing motor0 and say using motor0 limit ++ or -- then turn them on and use the same pin? under inputs in ESS config.

if you are using 2 switch's (home combined with one limit) then you will need a separate pin set for the other switch for limit++ or -- however your direction is setup...



? ?


 

Hi Terry
Thanks for reply.
I have tried using 1 limit and allocating it to both Home and Limit.
Problem is when Running G28 the limit trips and stops the Homing functioning, Logical I know!!!

So far I have not found a workaround for this.

No three switches


 

DazTheGas Did a video a while back on setting up the homing and limits don't know if that would help but wouldn't hurt? to have a look
