configure touchy

[scala...@free.fr]

Hello everyone,

is there a step by step to configure machinekit with touchy?

Machinekit works with gmoccapy and this configuration: What are the things I need to change for touchy to work.

thank you

I suggest looking at configurations for examples.

I have seen this page, the problem is that in my.ini file I change:

DISPLAY = gmoccapy ==> DISPLAY = touchy

then machinekit doesn't start anymore

I have not used touchy, but reading this:

http://www.machinekit.io/docs/gui/touchy/#hal-connections

Tells us that you need to add to your configuration a touchy.hal file.

First try to find in the current configurations for a touchy.hal file. Or maybe there is a simulation which uses touchy.

Touchy requires an MPG (hand wheel encoder) and a start and stop button available as HAL pins.

You scroll through file lists and a number of other things using the MPG, and you execute G-code programs with the start button.

So, those are hardware requirements.

Attaching a working touchy config from my machine. Key thing here is to understand that touchy is for touchsceen but considers this input as unreliable so start/stop switches and an MPG encoder are required.

I modified touchy slightly (therefore called touchy_ms in the ini file) to:

- get rid of functionality related to switching the single MPG to a specific axis (my machine has a dedicated encoder for each axis)

- enable glasscale inputs

Some pics on the machine can be found here: https://forum.zerspanungsbude.net/viewtopic.php?f=43&t=36394&sid=d528cd2187fabd4be60990dd0a3aaa92&start=10

After having used this for a while now I have found two issues with touchy that I have not yet resolved.

- The single-block execution switch is not working (seems to be wired correctly though)

- The message reporting (errors) is poor and mostly broken

I wired my MPG

in my setup.sh file there are

pins hardward MPG
P9_22     in         #IN-ENCODER-B
P9_24     in         #IN-ENCODER-A

pin hardward Abord
P9_28     low     #AUX-05

pin hardward cycle-start
P9_30     low     #AUX-06

then I added in my.hal file

newsig button.abort bit
newsig cycle.start bit

net button.abort <= bb_gpio.p9.28

net cycle.start  <= bb_gpio.p9.30

Is that correct so far?

I suggest you start touchy and then you start halmeter to inspect the hal pins to check if things are wired correctly and if your inputs work. That's how I did it.

Touchy exports some hal pins so you need to:

-  set the general hal magic in the main hal file 

- wait for touchy to start

- make some other connections in a postprocess step

Above code may or may not be correct, that depends on your machine. If touchy does not start, please provide the error message.

If other GUIswork then the postprocess step might be missing

I get an error message something like that:
GtkWarning _gtk_drawable_get_source_drawable:

I couldn't make a copy of the message I have my usb hub that doesn't work well, I ordered another one.

Finally now Touchy starts, the folder "nc_files" was missing in the linuxcnc folder.

As Malte suggests, I'm going to watch with  halmeter.

Thank you
