any one know how use analog inputs in mach3 for speed override, spindle override, ?
i tried use brain it recognizes the analog input but i dont know how terminate the rug for implement the two overrides.

It might not be THE information, but as I remember, Analog are not yet implemented yet in Mach plugin.
Art?

Are there others ways to use a potentiometer to control the feed and RPM on Mach3.
I saw a video on you tube showing that.
-
can you explain a litle more??

I have not tested it yet but Analogue Inputs via the Pokeys are in the latest plugin.

The analog inputs do work. I was able to hook them up and get them working this morning. However, I am experiencing a bit of a delay from the analog switches. The pokeys software reacts almost instantly but mach seems to have about a 1 second delay pulling the information in. I wrote a simple macropump to control the FRO and it does work. It very well could be my inexperience with mach, but I am very pleased to see that it is working even if it does need some minor tweaking.

I think there may be problems with the plugin as I have tried with a MPG hooked up and Mach has a big delay when winding the MPG. Art is in the UK at the moment so hopefully when he gets back he can have a look but certainly sounds like a similar issue that you are having with the analogue (analog for you USA guys ;) )

Hi All,
I've acquired a nice little Orac with a tool changer and are going to convert it to Mach 3.
I have already converted a Bridgeport to M3 but this is a basic system with just 1 standard breakout board+ shuttle.
Looking at the i/o extension options for Orac, the Pokeys looks great as I would like to :-
Operate the tool change (3 position sensor i/p and 1 o/p to index).
Fit MPG handwheels to give "manual machining control"
Travel limits
Speed and spindle speed override pots.......so far so good I think 8)
Also, op a 0-10v analogue signal to a new VFD for spindle control, I'm not sure if Pokeys does this yet? I (think) I will need to somehow isolate the analogue from the VFD?
Any ideas or advice would be appreciated.

The Pokeys does the analogue in and the MPG at the moment but its not perfect and needs a bit of work. The MPG has a fair bit of delay from my testing and hopefully this will be made better, not sure if its a plugin issue or Pokeys.
For spindle control you want to look at the Digispeed from homanndesigns.com There are others that do similar.

Hi Hood,
I like the look of the Pokeys as it appears to be an "all in one" for just about all my add-on needs and was hoping that it would O/p to the VFD to make a realy neat installation.
If not, the Pokey is still looks good and I'll fit a digispeed / other for the spindle speed control.
I did make a PWM to volt converter for my BP driven by the op from the PMDX but it hunts a bit so I will change this at the same time as fitting to the Orac.

Hi, would like to the pokeys for feed rate but don't know where to begin.
Could someone point me in the right direction to make some test.
I'm not an expert with mach3 and the use of the pokeys device.
So after hooking up the potentiometer to the Pokeys board, what should I do inside Mach3.
Do I use some OemTrigger, re-program some buttons. Just need some help . Thanks

Hi Guys:
The analogue, when used with a brain is a matter of scaling the input to a number from 1-100 for example, then sending it to a DRO number that reflects the function. ( like the FRO DRO ).
There appears to be a slowness in the way Im using it.. Ill discuss it with Boris..

I just hooked up the potentiometer to the Pokeys board at 3.3 volts as per the manual.
On the tool option in the Pokeys menu, I can see the analog diagram working.
I try to program some brains functions but don't know which ones to use.
I can program some buttons and outputs but for readind analog, I'm lost

did you ever manage to ge it working, I dont have a clue either and would like to do a bit of testing. Like you I have the pot working fine in the PoKeys software but dont know how to get it into Mach.

Hi Hood perhaps this Brain help you
-
Thanks gifre, I had a brain very similar to that but how do you get the pokeys connected to Mach for the Brain to see. In the Pokeys manual for Mach it says it is in the same spot as the G100 IO, thats what is getting me as I dont know where that is or how to enter it.

Hi Guys:
The G100IO and the Pokeys puts their analogeu signal in the SerialModBus IO block #124,125,126 and 127.
When your using a brain, you woudl use the SerialModBus input block address #124,125,126 and 127 to get the value of the anologue input.

Ok thanks Art, typical thick bas%&*d here, had the analogue input on pin 47 of the Pokeys but obviously its pins 43 to 46 only, 43 being address 124, 44 being 125, 45 being 126 , 46 being 127 and finally Pin 47 being IDIOT!!!
I now have it on pin 45 and its working fine exceping the slight delay and also depending on the speed I turn the pot determines whether I can get get min FRO or not. Example is if I turn fairly slowly it will go down to 0, if I turn fast it will only go down to 37 or so. If it is turned down and still reading 37 then as I turn it up it will start to lower at first then increase again.
