General Mach Discussion / Re: Help needed Connecting NPN Proximity sensors to BB`s

« on: May 11, 2008, 06:18:41 PM »

Thanks Guys for you input,

All seems like lots of  trial and error (and lots of smoke,If I stuff it up),so I might give it a miss

Yes ,Jimpinder the BOB is abit of a #?##@,I haven't had much luck with other things on the board as well, and as I have wasted enough time now,I think its going to look real nice sitting next to the other paper weight,the G100.
Another excellent purchase,NOT!!!!

Rather than pull all the switches off and rewire new switches ,I think I will just go and get another BOB,the one I was looking at to start with that handles these switches,
A pitty I was told different prior to purchase?

Anyway, thanks guys for looking into this for me,

Regards
Whatda?

Thanks Kenny,its actually a C23 ,from the same mob,
I will give it a go though,thank you

jimpinder,
This is excellent information,thankyou.

It all makes sence now, as they were working with the G100 ,providing 12 volts back to the digital input.!
I would of kept the g100 ,however it had problems talking to mach or the other way,not sure,and when it
did sensed the switch it always did something different.

............................... a pair of resistors in series connected between the 12 volts and the 0volts wires. These should be of the value 680ohms and 470 ohms  (preferred values). The output of the device should be connected to the junction of this "ladder".

I am trying to get a picture in my head as to what this would look like,  any chance of a  rough sketch to easy my elec.. challenged mind.
And then ,does the output go to one of the inputs to the BB.

Thanks very much for your info
Regards

Thanks guys for your input,

Safest way to find out would probably be to contact the maker of your breakout board and ask them.
Hood.

I have tried this,and he cant give my a clear answer???

Jimpinder

The reason for using these 10-30volt prox sensors,were that they came with the machine ,operating with a
very basic hand controller on 24volts ,and now I have converted over to Mach .
So before I go and rewire new switches I thought I would see if there was some way
of keeping them

The sensors are Omron TL -05MC1-2  , 3 wires (ie 10-30volt,  0 volt,  and output)
and have attached the pdf file for them.

Also I believe the input pins on the BB are low.

Any help before I re wire some switches would be good.

Thanks, regards

Whatda

Further to my question,the sensors output wire indicates 3.5 volts when the axis
is of the sensor ,and pretty much 0 volts on the sensor.

On connecting this wire up to one of the inputs on the bb,the voltage drops to 0.75volts.

Any ideas

Does Anyone know ,or can point me in the direction/post etc
to finding out how to configure/connect 12volt Proximity sensors
to a standard Breakout board.
I cant understand how to wire the one wire input (from the sensor) and
make it 5volts so the board can read it.

Any help ,would be great.

Mach3 and G-Rex / Re: Z zero macro and the G100

« on: March 21, 2008, 08:11:50 PM »

I guess I`ll keep it and HOPE someone finds a fix.
Going by the date/age of most of the posts here,
alot of people have abandon it,and gone for something else.
Such a shame,it has lots of potential.
At the moment it works well in certain areas, however ,except for the auto zero,
In which I would really like to use.

Anyway......NEXT.

No I thought not,
Oh well I better go and get the hammer!

HI all,
I have asked this  question on another post and thought I had it worked out...
But WRONG..!!!

Is there anyone out there who is using a auto Z zero macro with the lemon
,sorry I meant a G100, that works.

Before it(G100) gets put down by a bloody big hammer, I would be interested to hear from
anyone with a G100 that they are using and working.
