my f`irst hal `file need help was created by PhilipME

my f`irst hal `file need help

Category: General LinuxCNC Questions

I want to change the state of pin 17 on my breakout board. At this stage, I dont want any GUI involved.

I want to change the state of pin 17 by halrun command

halcmd: setp parport.0.pin-17-out 1

the hal file name secondhal.hal,      then I issue 
halrun -I -f secondhal.hal

loadrt threads name1=base-thread fp1=0 period1=50000 name2=servo-thread period2=1000000
loadrt hal_parport cfg="0 out"
setp parport.0.reset-time 5000
1addf parport.0.read base-thread
addf parport.0.write base-thread
addf parport.0.reset base-thread

but no change to bob pin 17
Can anyone help?



Good day

Philip

Make a new and clean installation on another computer, do not touch the existing computer. If you can run it on a new computer, reinstall it on your existing computer.

Spindle.0.at-speed False not inhibiting motion

Category: HAL

If spindle at speed signal goes false during a feed move, motion does not stop. It will only stop at the end of the current move,before the next move.

We have 3 deckels, all with gearboxes that are automated. I always invert the spindle at speed signal and connect it to motion.feed-inhibit to deal with this issue

You may be right about the timing because I tested the code below and works as expected, but I had to put G4 after the speed line.

refclockSyncCycle question

Category: EtherCAT

Hi , at all.
in many example ethercat.xml configuration files, the values ​​of refClockSyncCycles are different.
Sometimes -1 , sometimes 1 , sometimes 5 .
If you use a servo period in the ini file of 1 ms , what is the correct value to use ?
Keeping in mind that appTimePeriod is 1000000

Thanks

I was shy to ask where those shift arrays came from. So glad you've explained.

I hope for lightnings, thunder, heavy rain and a dozen typhoons all of Sunday. I'll cave under and get it done. Thanks a-mil again Oliver.

by the way, if you were wondering why there are such strange pin names at the top of the quadencoder:
        {
            "type": "quadencoder",
            "pins": {
                "a": {
                    "pin": "SHIFT_INPUT[2]"
                },
                "b": {
                    "pin": "SHIFT_INPUT[3]"
                }
            },
            "signals": {
                "position": {
                    "function": "jog.wheel_y"
                }
            }
        },

these are 'virtual' pins that are created when an expansion plugin is loaded:
        {
            "type": "shiftreg",
            "pins": {
                "out": {
                    "pin": "PMOD:P1"
                },
                "in": {
                    "pin": "PMOD:P2"
                },
                "sclk": {
                    "pin": "PMOD:P3"
                },
                "load": {
                    "pin": "PMOD:P4"
                }
            },
            "name": "shift",
            "speed": 5000000
        },

the expansion pins can be used in the same way as real pins in the configuration, except that they are limited to one direction.

Otherwise you can use them in pretty much any other plugin
even PWM or stepper if they don't need to be ultra fast

Oh and errr... now that I have the rio stepgens buzzing I hooked up a signal wire to my mill X step drive and, and ... Ready for it??

The Nasty Resonance Is Gone!!! Man those RIO stepgens are good. Used to sound like a freight train at several velocities before, so much so I bet my great great great neighbor half a mile away was hearing my sheet metal panels rattling. That mess will soon be resolved!!

Edit: as I was typing this, the awesome support from meister manifested itself once again. Not surprised though. That is so cool, great and spot on info - I look forward learning this

ok, jogging, grrrrrrrrrrrrrr

in general, everything can be configured as with mesa at the end via hal, the only problem is that this is overwritten when regenerating :(

To make simple assignments, there are the 'signal' -> 'net' options.
A strength of RIO is that even double assignments are recognised and if possible an AND/OR is built in between.

When it gets more complicated, for example when jogging (switching axes / speed / ..) the 'net' option no longer helps :(

but then there is the 'signal' -> 'function' option :)

there are a few predefined options
Examples 1:

2 Encoder
1. for Axis X / joint0
2. for Axis Y / joint1
        {
            "type": "quadencoder",
            "pins": {
                "a": {
                    "pin": "SHIFT_INPUT[0]"
                },
                "b": {
                    "pin": "SHIFT_INPUT[1]"
                }
            },
            "signals": {
                "position": {
                    "function": "jog.wheel_x"
                }
            }
        },
        {
            "type": "quadencoder",
            "pins": {
                "a": {
                    "pin": "SHIFT_INPUT[2]"
                },
                "b": {
                    "pin": "SHIFT_INPUT[3]"
                }
            },
            "signals": {
                "position": {
                    "function": "jog.wheel_y"
                }
            }
        },
Examples 2:

1 Encoder for all axis
joint/axis selection can be done in the AXIS gui
        {
            "type": "quadencoder",
            "pins": {
                "a": {
                    "pin": "SHIFT_INPUT[0]"
                },
                "b": {
                    "pin": "SHIFT_INPUT[1]"
                }
            },
            "signals": {
                "position": {
                    "function": "jog.wheel"
                }
            }
        },
Mixing Example 1 and 2 is not possible :(

this is a list of some rio functions:
RIO_FUNCTIONS = {
    "inout": {},
    "output": {
        "jog.selected-x": {"help": "X is the selected axis", "type": bool},
        "jog.selected-y": {"help": "Y is the selected axis", "type": bool},
        "jog.selected-z": {"help": "Z is the selected axis", "type": bool},
        "jog.position": {"help": "Position of selected axis", "type": float},
    },
    "input": {
        "jog.wheel": {"help": "Jog-Wheel", "type": float},
        "jog.wheel_x": {"help": "Jog-Wheel X-Axis", "type": float},
        "jog.wheel_y": {"help": "Jog-Wheel Y-Axis", "type": float},
        "jog.wheel_z": {"help": "Jog-Wheel Z-Axis", "type": float},
        "jog.select-x": {"help": "Jog-Select X-Axis", "type": bool},
        "jog.select-y": {"help": "Jog-Select Y-Axis", "type": bool},
        "jog.select-z": {"help": "Jog-Select Z-Axis", "type": bool},
        "jog.plus": {"help": "Jog selected axis plus", "type": bool},
        "jog.minus": {"help": "Jog selected axis minus", "type": bool},
        "jog.fast": {"help": "Jog set fast", "type": bool},
    },
}

i think we need a documentation for this, there are other function but i have also need to check what i have done there :)
last but not least, there are also a few add-ons that can be configured via the setup-gui:
riocore# ls riocore/generator/addons/
camera  classicladder  hy_vfd  joypad  mxmpg  README.md

it doesn't seem like much now, but we can still expand it and with the automatic links it is already very powerful and can create hal's that nobody would have to create by hand :P

Now fixed. They had a bug in the DKMS deb files. Grab this Linuxcnc ISO which has the new keys in it.
ISO:  drive.google.com/file/d/1gEQzgHsj_LjHiGB...k1Z/view?usp=sharing
Folder with all generated files:  drive.google.com/drive/folders/1pwDh_jn8...QcQwcLv7?usp=sharing

This  ISO also corrects installing a pre-release version of Linuxcnc and no installs 2.93 as intended. 
I have asked the devs to copy this ISO to the downloads page.

Hi MR.RODW
I have question
Because my PC a lot setup for 7i73 mattrixkey sendkey for setup in debian (permission) ,If I go to D/L .ISO and reinstall , I must go to setup all again, and not sure I can do it working again or not.
Can you share any solution for fix this error about DKMS and don't need  to reinstall with .ISO ?

Does the term VersaProbe only apply to the brand or probe or are the chinese-knockoffs included?

Additionally, what's the real difference between Basic Probe and Versa Probe in the QTDragon interface? Anyone know?

I’ll drag it out over the weekend.

Give us the heads up and hint us rather, i.e where to start to get a module written (template/example?). If we are to be using RIO for the next decade then it's imperative we know how to implement one of those cool plugin/module (not even sure of the difference between both, goes to show). So much to learn and fun ahead I'm sure.
