Hey. Got to the point where probing is needed. I use parallel port BOB for my machine and gmoccapy as gui. Could you help me with setting up touch probe?
My machine is working fine for me, I had touch off probe (Z) set up earlier and havent used it.. I guess my setup (files, code lines etc) arent "standart" anymore.
github.com/verser-git/probe_screen_v2

I found this thread. And already stuck on 2.
"Add to your .ini ...-postgui.hal settings from my-mill.ini and my-mill-postgui.hal, substitute your own constants."
At first, do I copy all files from this link to my config folder?

All except the HAL and INI, yes. You need to merge those with yours.
If you don't already have a postgui.ini then you can use that file as-is, but still need to merge the relevant parts of the INI. (mainly just adding a reference to the postgui.hal)

That debian 10 distro has several issues. Basic stuff like the network manager, the SMB settings, the time settings, the sleep/screen saver just to name a few, all have to be fixed. IMHO Linuxcnc needs a larger community, but with ISO's like that deb10 it's going to be tough.

I'll give it go for awhile, but i think that Mesa card is going in the trash, to be replaced by a Ethernet Smooth Stepper. Mach3/4 has its issues but has worked for many years on my mill.

 

I'm running debian 10 with Mesa hardware without issues - you don't need to run the network manager - I don't.  For a LinuxCNC set up one does not want to do a standard install - just install the minimum - start without even a desktop - and then add in only the packages you really need.

I have some messy cryptic notes about setting up Mesa at lrak.net/wiki/LinuxCNC.html -

I'm running with the KDE desktop - or I could give you a package list to base it on.   I even stripped out several packages that loaded daemons that are in the standard LinuxCNC install.

Not sure why you would want to run Samba on CNC box?  I think Windoze has a way to do NFS mounts these days - I think they even do sshfs now?

Time settings are taken care of by systemd - you might be confused that hardware time is zulu? Windows has used local time - which causes all sorts of grief for companies that span time-zones.
It is simple to remove screen savers..

Any time you move to a new software, it causes stress.  The first text editor you use tends to be the 'best'.  Same with CAM systems..

Every time I use the +x to zero my x, it adds a -0.010 to the offset. Here is a video showing what’s happening and an image to show active g-codes.

Be aware there's a big issue in probe screen ng.

linuxcnc.command.wait_complete() is not being checked for a timeout, the timeout is 5seconds, and it uses G1 for traveling from one side to another one of a stock.
If the stock is large enough and the feed rates are slow enough a timeout might occur while the psng scripts still continue to run. The output might be completely unexpected (which happened to me).

github.com/sundtek/probe-screen-ng

base.py

            self.command.mdi(l)
            rv = self.command.wait_complete(50)
            if rv == -1:
                message = _("command timed out")
                secondary = _("please check self.command.wait_complete timeout in psng base.py")
                self.warning_dialog(message, secondary=secondary)
                return -1
