Touchy and Keyboard

Hello,

I am working in a manual lathe conversion to CNC using LinuxCNC V2.5.0. Currently it is working with Axis, but i want to switch to Touchy. Before i make the CNC panel and buy a touch screen monitor i want to test it with the PC keyboard.

Do you have any example how to connect the Touchy button's (Abort/Start/Single block/Wheel counts) to the PC keyboard ?

Thanks you in advance,
Victor

you could use hal_input to connect a keyboard (like a second one) or any USB HID to connect to touchy.

I can't see any formal description in the manual on hal_input but there are man pages.

It is working, the solution is:

INI File:
[DISPLAY]
EMBED_TAB_NAME=GladeVCP demo
EMBED_TAB_COMMAND=gladevcp -c gladevcp -x {XID} -u hitcounter.py -H gladevcp-touchy.hal manual-example.ui

gladevcp-touchy.hal file:
#Program Stop
net cb1 gladevcp.check => gladevcp.led1
#net cb1 => halui.program.stop
net cb1 => touchy.abort
#Program Run
net b1 gladevcp.button => gladevcp.led2
#net b1 => halui.mode.auto halui.program.run
net b1 => touchy.cycle-start

But now I HAVE A NEW PROBLEM:
In Touchy GUI the X and Z axis moves only at 100 mm/min regardless of G0 or G1 program code. That does not happen with Axis GUI.

100 mm/min is the only value, regardless of G0 or G1 program code.

Did you create a whole new config, or just change the GUI line in the INI file?
The first place I would look would be in the INI file in the [TRAJ] and {AXIS_N] sections

I use the same ini file as in Axis GUI, wich is working OK. I only have changed in the ini file:

[DISPLAY]
#DISPLAY = axis
DISPLAY = touchy

and i have uncommented an EMBED_TAB_NAME and an EMBED_TAB_COMMAND in order to use Start and Stop buttons in a new GladeVcp tab panel.

Will it move slower than that?

Yes, if the G1 code is slower than 100 mm/min.

What happens if you increase feed-override?

I don't know, but with halmeter i see:
motion.requested-vel 133.3333 (velocity mode, equals to 8000 mm/min)
motion.currente-vel 1.6666 (velocity mode, equals to 100 mm/min)

motion.requested-vel OUT FLOAT The requested velocity with no adjustments for feed override
motion.current-vel OUT FLOAT Current cartesian velocity

it doesn't make sense.

Victor

You are right, it doesn't. What is feed override set to? (Should be visible somewhere in HAL)

halui.feed-override.value is set to 1

but thanks to your idea i have found halui.max-velocity.value set to 1.6666 (i don't know why) (x60 = 100 mm/min)
(halui.max-velocity.value float out Current value for maximum velocity)

so i set in hal:
setp halui.max-velocity.scale 50
and connect a "pulse" button to it:
net halui-pulses-maxvel touchy-buttons.hal_button_pulses_maxvel => halui.max-velocity.increase

the problem now is that the maximum value allowed for halui.max-velocity.value is 125 (7,5 mts/min) half the X and Z axis as is configured in the ini file (250 = 15 mts/min)

Any idea ? Is it a touchy bug ?
