Very cool ... good job !
Now ... (I just gotta see that macro )

Thanks TP,

Hi Russ , It would be easy to TEST the stability of the analog value in UCCNC.

Start with a 5v signal and add a resistor to bring it down to what ever voltage level you want to test at.

Then create a macro loop to monitor teh analog value over time. You could write teh values to a log file so that you could SEE any diviation and what level of diviations might occur over time.

You could also use 2 channels to show what teh original volt level is (5v) and another channel to show the test volt level (1v or 1/2 volt)

THEN you would know for sure (;-) UCCNC is VERY handy for things like this.

OR maybe someone could write a simple plotting routine plugin to show it as a plot over time.

IF you bring out the values as a CSV file then you could import it into a spreadsheet and plot it out from there.

Hi,
I can also monitor the analog inputs at the bottom rt. of the diagnostic page.
The manual doesn't describe it though. (everything except)
Using four 1K resistors in series I get the following 5 digit representations for each position. (only using 1 channel.)
The highest being direct to 5V. (they are not in any particular order in the pic. )

What does this 5 digit value actually represent ? I was expecting the actual voltage.
The values only waiver by about +/- 15 ..... then settle in and become a bit more steady. I imagine temperature will cause a slight variation as well, but well within a set tolerance in a macro ?
Thanks

From where did you get those values?
In the UCCNC the analog value is represented as a 16bit number (0-65535 values) for the 0-100% input range.
So, it has to be your macro who converts the values to the format you got in that file.

Temperature variation can cause a drift in the -40 to +125°C range, if I recall it is +-3 low significant bits maximum, but I can look it up in the microcontroller datasheet which has the AD converter built in...

Those number are what UCCNC displays for teh analog input values . They are 16 bit values of teh voltage apparently.

I would have thought UCCNC would have displayed them in volt values seeing the input was in volts (0-5v). To get Voltage values divide that number by 13107 (65535/5v).

Hi, those are displayed on the diagnostics screen, lower RIGHT corner.... and are updated regularly. At what preset frequency, I do not know. There is no macro necessary, it is "in there".
Thanks,
Russ

Thanks TP .
That comes out to "pert dang neer" rock solid !
I think I can trust that ...... thanks
Might be able to come up with other uses for this.
In series with a momentary button, could greatly expand the I/O .... for other certain functions.

Is it possible someone give me step by step instruction to change port / pin M25020 & M25021 ?
My X, Y, Z, A (no B, C) selection port & pin are ;
X = port 5, pin 4
Y = port 5, pin 5
Z = port 5, pin6
A = port 5, pin7

I changed M25020 as follow but not working.

// =============== Inputs - Port, pin, negate

const int portMPGX = 5;
const int pinMPGX = 4;
const bool negMPGX = false;

const int portMPGY = 5;
const int pinMPGY = 5;
const bool negMPGY = false;

const int portMPGZ = 5;
const int pinMPGZ = 6;
const bool negMPGZ = false;

const int portMPGA = 5;
const int pinMPGA = 7;
const bool negMPGA = false;

const int portMPGB = 0;
const int pinMPGB = 0;
const bool negMPGB = false;

const int portMPGC = 0;
const int pinMPGC = 04;
const bool negMPGC = false;

Thank you in advance.

There are the MPG pins on the I/O setup page. And the buttons etc. you select where you showed on the printscreen.
The increment selection knob is a bit more tricky, because it will not trigger when you start the software, because the knob is not changing the input state.
One way to resolve this issue is to wire a PWM signal through the knob instead of a fixed voltage, e.g. the charge pump PWM is fine for this purpose and then it will update the knob continously, so the selection will update to the actual value on software start.

Hello!
I decided to ask here instead to open a new topic since I have a similar pendant, bought on eBay, to be connected to the AXBB-E

Similar but not the same.
It have the usual 4 wires for the MPG, the two knobs for axis and increment but the knobs are connected in series to a button to enable the pendant.

I'm not sure I understand the input state issue.

Did the enabling button solve the issue?
Starting the program with the button released means that the state is 0 and since it changes when the button is pressed the system could work?

Since it requires multiple connections to work properly (X, Y Z and 1x 10x 100x), is it better to buy the UCSB to connect them at the LPT port?

I'm sorry but I'm ignorant about electronics, so I need to ask everything.
