limit switch problem

Hi ...after finally getting a micro switch wired up for limit switch,,,light shows on/off on mesa7ip6s board,..hal meter shows working... but when I run axis and hit switch held in my hand....no change....keeps moving. been at his all day...I usually like to figure things out myself but now I am weary...grateful for some help if possible.

Thanks,

Rick

So This from HAL May be wrong or incomplete?

Anything needed in ini?

Thanks for reply!!

Not sure if this is a pncconf version issue but current pncconf does this:

# external input signals

# --- HOME-X ---
net home-x     <=  [HMOT](CARD0).inm.00.input-00

# --- HOME-Y ---
net home-y     <=  [HMOT](CARD0).inm.00.input-01

# --- HOME-Z ---
net home-z     <=  [HMOT](CARD0).inm.00.input-02

From this:

 


In your hal file you have# --- MIN-X ---
net min-x <= hm2_7i96s.0.gpio.000.in_not

but net-min-x is not connected to anything so is not functional

the actual signals connected are these (also from your hal file)

# ---setup home / limit switch signals---

net x-home-sw => joint.0.home-sw-in
net x-neg-limit => joint.0.neg-lim-sw-in
net x-pos-limit => joint.0.pos-lim-sw-in

so if you changed

# --- MIN-X ---
net min-x <= hm2_7i96s.0.gpio.000.in_not

to
# --- MIN-X ---
net x-home-sw <= hm2_7i96s.0.gpio.000.in_not

you should get some function

(I am glossing over the difference between the INM inputs and GPIO inputs
as they can be used interchangeably on the 7I96/7I96s, that is GPIO 0..10
behave the same as INM 0..10)

Hi..Thanks for reply...I made change...same result...I made the change under the external input signals...is that right?....if so... I am not familiar with homing variables...anything that could be set wrong to make switch ignored?

Thanks again for your help..

the actual path  of x home (in your hal file) should be:

net x-home-sw <= hm2_7i96s.0.gpio.000.in_not

net x-home-sw => joint.0.home-sw-in

So trace from hm2_7i96s.0.gpio.000.in_not to  x-home-sw to joint.0.home-sw-in

ok...thanks...I will do on monday...in the meantime check out halshow


Thanks!!
