Welcome to LinuxCNC.org

I had a little time and decided to re work the joystick control on some of my machines (cnc router, knee mill and lathe).
Originally I added several features such as incremental jog, touch off, spindle control, etc.
Some of these, such as the incremental jog required a round about way when working on earlier versions of EMC2.
Now with the available new components such as toggle and halui pins like incremental jog it is easier.

Below shows John's Simple Remote Pendant with Incremental jog added.
## comments were added to show changes.

It has not been tested yet and needs some house keeping. I will add a beep to indicate which mode it is in for machines where it is not easy to see the monitor and a indicator on the panel.

It works as originally set up but now has 3 incremental jog settings (small, med. and large)

The incremental jogs require the sticks to be pushed all the way to activate to avoid accidentally jogging the wrong axis by not pushing the stick perfectly straight.

To toggle between continuous jog and incremental jog just hit the #4 button.

Pretty cool Rick!

Did you add this to the wiki?

John

Thanks John,

Have not updated the wiki yet, that is on my list of things to do.

I plan to do away with the original as it is so dated and replace it with one that details one feature at a time stating with the incremental jog.

Rick G

As John pointed out in his original article the jog buttons only work in Manual mode.

In case you are in MDI mode and away from the keyboard when you want to jog the below line will allow you to switch to manual mode and jog with the joy pad. Just add it to your custom_postgui.hal and when you push the left stick straight down halui will switch to manual mode.

net halui-man-mode halui.mode.manual <= input.0.btn-base5

This will not change the display in AXIS, but will allow you to jog.


Another simple change, the below line will give you an estop button, I used the number 9 button.

net halui-estop halui.estop.activate <= input.0.btn-base3


Edit:
Another later version now does allow you to change AXIS from manual and MDI mode.

wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding...imple_Remote_Pendant

Now has some updates with...

Three proportional speeds of jogging

Three incremental jog sizes

Buttons to switch from proportional to incremental jog and back

Set coordinate for each axis with G10, can be zero on whatever makes sense on your machine with audible feedback

Toggle coolant, spindle, etc. on and off with one set of buttons

Adjust spindle speed

Adjust feed rate

E stop

Buttons to Switch from Manual to MDI mode and back

Launch sub program such as Send machine home, first retract z to chosen position then send and x y home or another sub.

Start, Pause, Resume, and Stop buttons
