Re: [Emc-users] Regression in pyvcp's radiobutton from 2.5 to 2.6.5, nothing selected in the hal layer on startup
Hello Schooner30, thanks for your reply. I had a look at it too today and came up with with this working code: n=0 for c in choices: b=Radiobutton(self,f, text=str(c),variable=self.v, value=pow(2,n)) b.pack() c_halpin=halpin+"."+str(c) pycomp.newpin(c_halpin, HAL_BIT, HAL_OUT) self.halpins.append(c_halpin) if n==initval: b.select() pycomp[self.halpins[-1]]=1 n+=1 But I like your solution better, because your: pycomp[self.halpins[initval]]=1 is more readable than my: pycomp[self.halpins[-1]]=1 So please do submit your patch. @cradek: Since Schonner30 has a better/more readable fix I will not persue this with my own patch anymore. But thank you for your informations on how to submit a patch anyway on the irc channel.

Re: [Emc-users] Regression in pyvcp's radiobutton from 2.5 to 2.6.5, nothing selected in the hal layer on startup
Hi I have tested your code on 2.6.3, 2.7 and 2.8 All of them produce a pyVCP panel with button 3 selected But no, the respective pin is not selected, I think I may know why. When I made a lot of alterations a while back to pyVCP, I changed the update code, so that it did not keep cycling through updates every call unless there was a change. This will have suppressed the first update. I expect no-one has noticed until now, because the initval will generally reflect the default setting rather than actually set it. Thereafter all clicks upon radio buttons will work as anticipated I have written a fix, which seems to work OK. Will do a bit more testing and submit a patch to correct this regards -- New Year.

Schooner: Please check your latency-test results with the NVidia drivers
loaded and working. I found it very hard to backtrack to the nouveau or
vesa drivers when my 8 or 9 microsecond latency-test results were replaced
by several hundred milliseconds of lag. I was limited to about 2 ipm while
doing sw stepping on an older athlon single core board. The motors
sounded very ragged, and were simply were visibly stopping while glxgears
was running.
In short, 5 years back up the log, using the then current NVidia driver
kit was IMO, totally incompatible with linuxcnc as it locked out the IRQ's
needed in order to get the performance it gives to the video.
If that situation has improved, and NVidia drivers now play well with
LinuxCNC, I'd be happy but unaffected as the real machinery here is being
driven by D525MW intel boards.
I do have an NVidia based GeForce 8400 GS card in this machine, but have
studiously stayed away as generally, the nouveau drivers are good enough
to watch a new site video.
Thank you.
Cheers, Gene Heskett

Re: [Emc-users] Wheezy and Nvidia
I John.
I've got same problem as you with an asus graphic card (nviadia gpu) and
Debian wheezy.
No way to install the nvidia drivers properly.
At the end of a long story I re-install the LinuxCNC Wheezy distribution
and leave the video drivers it automatically detect
and it is fine (resolution 1280x1024).
On my side the problem mainly was related to the kernel specific drivers
requested from the nvidia gpu (LCNC Wheezy kernel is not the standard one
because it is patched for the RTAI (PAE)) .
As someome point me out (maybe Sebastian) it is not possible to install the
proprietary drivers on the Wheezy LCNC distro.
Maybe it is not impossible for some "guru" but for me it is.
So I went straight to the easy way. ;-)
Regards
Alex

Re: [Emc-users] Wheezy and Nvidia
Hi John
I have a Nvidia GT630 GPU card working fine on Wheezy 32 & 64 bit
Works with nouveau and if you download the nvidia-glx package, DKMS
builds the driver fine (you need headers and a build environment)
What you then need to do however is add
/etc/X11/xorg.conf.d/20-nvidia.conf as attached
Then check that the driver has been installed to
/lib/modules/{kernel-version}/extra/nvidia.ko
and /etc/modprobe.d/nvidia-kernel-common.conf is present blacklisting
nouveau
The only problem I have had is when doing a load of stuff at the same
time after building the driver and re-making initrd-img, which somehow
screwed things up, but
redoing everything sorted it

Mick

[Emc-users] Wheezy and Nvidia
I have a desktop computer with built in video. It is a Nvidia GeForce 6150SE nForce 430. When I try any driver besides the stock driver using info from the web one of two things happen, it reports that the driver is broken and won't install it or if it installs and I add an xorg file the computer goes just so far during boot up and stops at a blank screen with a blinking cursor. Has anyone used a nvidia video card with wheezy? Thanks JT -- New Year. New Location. New Benefits. New Data Center in Ashburn, VA.

Re: [Emc-users] Manual Mill Setup Question
I have no drill press now - just a couple of CNC'd mills - one with a quill. What I do is I use my MPG to twiddle handles when moving manually. I can control the spindle, zero DRO axes, etc all via the MPG. This mill (with quill) uses the XHC-HB04 MPG pendant, wired version, and it's great. I'm thinking of CNCing my last manual mill... Just my two cents (Canadian); John. -- New Year. New Location. New Benefits. New Data Center in Ashburn, VA. GigeNET is offering a free month of service with a new server in Ashburn.
