Hello to all
i can run my cnc miller (bridgeport mk2 with control tnc 151b) thanks to this forum, but still need one thing more, mi electronic handwheel can't work and apparently dont have any damage, i believe that there is a parameter 171 but already attempt with 0 and 1, which is the correct one? plus i dont know if its connected well, in my machine this connected one in a place different to the manual. i attach 2 photos.
somebody can help me

Yours is also correct, although very different from my 151, I don't have that connector at all! Look in other places in the manual and you will see this connection style.

there are also 2 and 3 as options for that parameter

thank you for your answer Gus, unfortunately my manual don't have more information and i don't know if my handwheel its connected well, one more question, what its the difference between the parameters to 171 (0,1,2,3)?
thank you and regards

download the full tech manual from heidenhain.com

I am not quite sure, perhaps machinetek knows , has to do with 2 different handwheels and two different something else, dunno what the something else is

shouldn't hurt anything by changing, just more not working

thank you Gus, i willl try to follow your suggestions.

There are four possible values for parameter 171 which select which hand wheel and touch probe system is connected:

0 = HR150 or HR250 and TS510
1 = HE310 and TS510
2 = HR150 or HR250 and TS110
3 = HE310 and TS110

TS110 is a cable connected touch probe
TS510 is optically connected to a remote unit that then is cable connected

So you need to decide which handwheel you have and select for it. I think the fact that the touch probe is not connected is irrelevent to this parameter

thank you awemawson, but i already attepmt all and nothing and begin to think that my handwheel its damage of something way, some form (parameter, button, etc) exist of something this blocking this handwheel?
thank you.
