qtdragon mod

Do you mean you are using HALUI to do MPG jogging?

No, I added my pins and linked them to jog_increments widget: [/code][/code][/code][/code][/code]

adding:
        self.w.jogincrements_linear.setEnabled(0)

to the end of
    def init_widgets(self):

Will make it not respond to screen clicks, but should still respond from HAL pin changes

Oh, that works great, thank you very much. I even made a small function that checks the active HAL pin against the widget every time the encoder signals, but your method is much more elegant.

New question: how to connect a button to a HAL pin? I want to add an MPG on/off button. I created a HAL pin in the handler file and created IndicatedPushButton. In the button properties, I added HAL.set_p(’mpg.mpg-enable’,’1’) to true_python_cmd_string. But I got an error:

  File "<string>", line 1
    HAL.set_p(’mpg.mpg-enable’,’1’)
              ^
SyntaxError: invalid character '’' (U+2019)

you could use a PushButton (under the linuxcnc-HAL heading)

It makes a hal pin.
Don't forget to set the property:
pin_name and pin_type

Finished the mod for qtdragon, which adds HAL pin encoders for all sliders, jog on all axes, increments, and MPG.

Add HAL pins for XYZABC axis jog:

qtdragon.jog.axis.x.plus
qtdragon.jog.axis.x.minus
qtdragon.jog.axis.y.plus
qtdragon.jog.axis.y.minus
qtdragon.jog.axis.z.plus
qtdragon.jog.axis.z.minus
qtdragon.jog.axis.a.plus
qtdragon.jog.axis.a.minus
qtdragon.jog.axis.b.plus
qtdragon.jog.axis.b.minus
qtdragon.jog.axis.c.plus
qtdragon.jog.axis.c.minus

For example, following pins are available for feedrate slider:

qtdragon.feed.override.count-enable = HAL_BIT, IN must be TRUE to enable feedrate counts
qtdragon.feed.override.counts = HAL_S32, IN encoder input for change feed override
qtdragon.feed.override.btn-100 = HAL_BIT, IN reset to feed override to 100%
qtdragon.feed.override.step = HAL_S32, IN increase/decrease step as a % of the maximum value

For sliders JOG_RATE and ANGULAR_JOG add pins to toggle between fast and slow jogging:

qtdragon.jog.override-linear.turtle = HAL_BIT IN decrease jogging in 10 times
qtdragon.jog.override-linear.turtle-led = HAL_BIT, OUT indicated slow mode is on
qtdragon.jog.override-angular.turtle = HAL_BIT IN decrease angular jogging in 10 times
qtdragon.jog.override-angular.turtle-led = HAL_BIT, OUT indicated angular jogging slow mode is on

Add HAL pins for MPG:

qtdragon.mpg.mpg-enable = HAL_BIT, IN must be TRUE to enable MPG counts

Jog increments pins, used first 3 INCREMENTS from ini file:
qtdragon.mpg.mpg-inc.1 = HAL_BIT, IN
qtdragon.mpg.mpg-inc.2 = HAL_BIT, IN
qtdragon.mpg.mpg-inc.3 = HAL_BIT, IN

For angular axis used next pins, also first 3 value from ini:
qtdragon.mpg.mpg-angular-inc.1 = HAL_BIT, IN
qtdragon.mpg.mpg-angular-inc.2 = HAL_BIT, IN
qtdragon.mpg.mpg-angular-inc.3 = HAL_BIT, IN

Pins for axis selected:
qtdragon.mpg.axis.x = HAL_BIT, IN
qtdragon.mpg.axis.y = HAL_BIT, IN
qtdragon.mpg.axis.z = HAL_BIT, IN
qtdragon.mpg.axis.a = HAL_BIT, IN
qtdragon.mpg.axis.b = HAL_BIT, IN
qtdragon.mpg.axis.c = HAL_BIT, IN

MPG encoder pin:

qtdragon.mpg.encoder-count = HAL_S32, IN MPG encoder input

Add a pins to cycle change increments:
qtdragon.mpg.mpg-inc.cycle = HAL_BIT, IN
qtdragon.mpg.mpg-angular-inc.cycle = HAL_BIT, IN

Put this file into <YOUR CONFIG FOLDER>/qtvcp/screens/qtdragon_hd/. Tested on qtdragon_hd, but should be working on qtdragon too.
