I have also changed the jumper for the index channel to single ended operation. it doesn't work... what am I doing wrong? also I am testing by using the command setp hm2 7i92 encoder.03.index.enable 1 (etc command probably is wrong here as I am working from memory but it changes the pin color in hal configurator) I can see the proxy is switching as the led turns off and on at the back of the thing for reference here is the link to the proxy I am using https://www.aliexpress.com/item/32867535621.html?spm=a2g0s.9042311.0.0.3a3b4c4d5BJjid On Thu, Jul 8, 2021 at 7:37 AM Peter C.

I would check the prox voltage ouput voltage in both states You can check the index state directly in hal by monitoring hm2_7i92.0.encoder.0N.input-index (N is the encoder channel you are testing) I think this is inverted from the pin state. Note that if you do not have the stiff (270 Ohm or so) pull down resistor, the prox output will always be high (around 5V) Peter Wallace Mesa Electronics _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
