Hi folks,

I'm praying somebody here can help me. I've been trying for the past few days to set up touchy (the touch screen friendly GUI) in linuxcnc, so I can use it with my new touch screen monitor instead of the default "axis" GUI. Has anyone had any joy successfully getting this working? I've followed all the relevant documentation on linuxcnc's website but I don't find it particularly helpful at tbh.


Any info of how you get linuxcnc to boot the touchy GUI would be much appreciated..

Many kind regards

John.

What problems are you having? Error messages, those kinds of things would help us help you. There've been many successful implementations of the Touchy screen. We need to know more about what issues you're having to be able to help you out.

Have you created the touchy.hal file and set the DISPLAY = touchy under the [DISPLAY] section of your .ini file?

Hi Mark,

Thanks for the reply.

I've created a file in the same folder as my .ini file and called it touchy.hal, and I've also changed "DISPLAY = axis" to "DISPLAY = touchy".



The error I get when I try and load LinuxCNC is:-

Does any text have to go in the touchy.hal file I have created? At the moment it is just empty and I don't really see what this file is meant to be doing as it is...


Many thanks for any help in advanced.

John.

OSError: [Errno 2] No such file or directory: '/home/jamesbishop/emc2/nc_files'

change ~/emc2/nc_files to something that exists under "program_prefix" in the [DISPLAY] section of your ini.
it most likely should be ~/linuxcnc/nc_files

Were you running classic ladder with your system under the Axis interface? What do you use the classicladder for, toolchanger, touch plate, or?? Looks like the classicladder_rt is interfering with Touchy. Need it or not, try to comment it out of your hal file and see if Touchy will run. If it runs, then you will have to see where loading the classicladder_rt needs to be or how to implement when using Touchy. I suspect this may be one of the 'needs of a separate Touchy hal file,but don't know first hand. I've never messed with Touch firsthand, just looking at your dmesg file.

Beat me to it. If the OP looks above that portion of the message, he'll see his configs directory as "/home/jamesbishop/linuxcnc/configs", so I would bet that changing the emc2 to linuxcnc in the ini file would fix the problem.

[lew90nicis]

Thanks guys, major help! That's cracked it! Really appreciate your help, couldn't have done it without you.

[wendtmk]

Outstanding! Glad you got 'er going!

Just for curiosity's sake, I was wondering how the emc2 got in there. Was it a cut and paste from the web site or documentation, or was it a legacy item from one of your previous installs? If it was a cut and paste, we need to get that documentation fixed.

Why touchy and not Gmoccapy? It's pretty darn awesome as a touch GUI and is used in industrial production lines.
