port parallel
I must to change my mother card of my computer HP and on this card no parallel port.
I'm buying a new one and install on mother card.
In the bios the adress of the card is 3F8 IRQ4, and i have of choise of three other one, when i see detail on windows the ressource are dc00//dc07 et dc880//d883.
Under windows no problem to print somethings, and i ears the noise of my breakboard cnc.
under linux ubuntu 10.04,I install a new printer brother on parallel port and i can print what i want whitout problem.
When i laught linuxcnc, no problem on the screen, all is all right, but when i connect the break board nothing move, and under mach 3 the mouvement is ok.
i suppose that the parallel port is not connect under linux cnc (0x378) (perhaps, i am not a specialist) and
salutations

Region 1: I/O ports at d880 [size=4]
Capabilities: <access denied>
Kernel driver in use: parport_pc
Kernel modules: parport_pc
You need to blacklist parport_pc by going to /etc/modules.d/linuxcnc.conf
and uncomment (or create ) a line
install parport_pc /bin/true
Then in you hal file change the line
loadrt hal_parport cfg="0x378 out"
to
loadrt hal_parport cfg="0xdc00 out"
That should stop the port being claimed by parport_pc and get linuxcnc to see it

i don't find the folder etc/modules.d/linuxcnc.conf but i find in an another folder etc/mdprobe.d/ "linuxnc.conf" is it the good one???
i see in the file the line #install parport_pc /bin/true but i can't remove the #
if it's the good one i can't change anything becaus is looked and i can't change the security because iam not the "propietaire" of this files.
i change in my hal file it's not a problem it's ok

That's the one, did it off the top of my head and got close!
i see in the file the line #install parport_pc /bin/true but i can't remove the #
Just run sudo gedit from a terminal and open the file to edit it

My mill move, but not well.
The motor don.t move enough. The command of linuxcnc Is ok but the breakboard Is not correct.
I try With stepconf for test every axis xyz without résult.
What Is the paramètre i must change. In hal? In ini ? For trying i used old parameter i used in my old version. Base thread 19300. Servo thread 63000.

You need to post a zip of your config folder, impossible to guess
Unless you have a hugely fast PC those figures are way off
Try Servo 1000000 Base 100000 to start with
and check that your SCALE= figure is right for your micro stepping, gearing, thread pitch etc.

i have an error " rtapi error unexpect realtine delay task 1 "
i run 3 glxgears in the same time and the result jitter max is 158970 after 5 hours.

Unfortunately high latency is not something that can be edited out by changing variables
![:P :P](/media/kunena/emoticons/tongue.png)
The only thing that jumps out immediately in in your hal file
setp parport.0.reset-time 105000
This figure is 200 times higher than the one on one of my machines, try setting it to 1000
Your MB is AMD, with an AMD / ATI chipset, so there is no SMI to consider.
The video could be problematic if it is reacting to glxgears

You can try the vesa driver and /or the software gl libraries
Looks like the fglrx driver can be problematic, especially if you have the closed source propriatary one
You may want to try the open source one, or if that is already installed just the vesa one
