xpro V3 sphinx 55 - how to get current position?

Hi,

I'm using the sphinx 55 with the xpro V3, and i'm trying to figure out how to retrieve the current xyz coordinates.

I've tried M114, $? and ? to no avail.

What am I missing ?

 

Thank you for your response.

in CONTROL '?' wasn't doing anything which confused me, but i noticed that in a normal terminal it was indeed printing out:

<Alarm|MPos:0.000,0.000,0.000|FS:0,0|WCO:-290.000,-42.998,-321.999>

Do you have any tips on how to filter out just the positional data?

Also, I noticed everytime i reconnect to the serial port that the positional values jump back to 0, is there a way to change that?

 

Thank you for your help I managed to get this working nicely in C#.

I can't find AutoReset, is it a jumper or in software?

Back to the parsing of the '?' result; my solution for that one guy that'll read this in two years:

Code:

enum Mode {Run, Idle, Alarm };
Mode currentMode;
Decimal[] curPos = new Decimal[3];

private void getState(String input)
{
    char[] delimiterChars = { '<', '>', ':', ',', '|' };
    String[] words = input.Split(delimiterChars, StringSplitOptions.RemoveEmptyEntries);
    Enum.TryParse(words[0], out currentMode);
    for (uint i = 0; i < 3; i++)               
    {
        curPos[i] = Decimal.Parse(words[2 + i]);
    }

    System.Console.WriteLine(input); // DEBUG
    System.Console.WriteLine("Mode: " + currentMode.ToString());  //DEBUG
    for (uint i = 0; i < 3; i++)                //DEBUG
    {
        System.Console.WriteLine(curPos[i]);
    }
}

Calling this with the result of '?' e.g.:

Code:

getState("<Run|MPo:300,2.8,2.9|:5,|O-3.0,3699-2.9>");

outputs:

Code:

Mode: Run
300
2.8
2.9

This makes it easy for me to find the state and positional data. I don't really know what the rest of '?'s result is or where to go to read further.

More specifically, is there a list of 'modes' the cnc can be in? so far i've figured 'Run, Alarm, Idle'.

 

Answering my own question

Code:

    runStatus: "Pending", // 0 = init, 1 = idle, 2 = alarm, 3 = stop, 4 = run, etc?

I assume this is it EDIT: i am wrong. I want to hold on some code until homing is done, i'm not sure if the status during homing is 'init' or 'run', but i would think holding until status is 'idle' is the right way forward.

 

Thanks, i found through your link the states: Valid states types: Idle, Run, Hold, Jog, Alarm, Door, Check, Home, Sleep

Sorry for the noob questions, I am completely new to the world of CNCs, and am only figuring out what Grbl / architecture of my hardware and software is.

As for my board, i'm using what was recommended when i got the sphinx 55, the xPro v3.

 

You may ask.

We are using 'control' to jog the cnc and am very happy with it (it's a very neat piece of software, I assume you had something to do with it, thanks!).

Other than that, I'm writing software to automate a task that plots several thousand pre-calculated points and rests for some time while a probe takes some readings.

I have learnt basic G codes that has allowed me to finish this (i'm currently testing/debugging/optimising). But the structure of Grbl, where you guys come in, why some M codes don't work in certain controllers etc is still something I'm figuring out.

My understanding is, Gcodes is some semi standardised language to control CNC machines. Grbl is some open source cnc/g code controller? You guys have made some decent hardware that interfaces with Grbl. Is this right?

 

I know i can inject gcode files into 'control', but the end users will be some physicists in my lab and they really only want to see relevant options that make sense for the task / measurements.
