My Intel D2700MUD will just barely do a 400000 servo thread. But I think i backed it off to 500000 for reliability.

Mine for some reason my D510 won't work.
I found the parallel port address using the terminal,
and used it but got a pipeline error where I can't jog within stepconfig or launch LinuxCNC. Is there a simple fix for this?
The new system has under 10,000 latency, a 60GB Intel SSD, and 1 GB of ram. I'm rather stumped.

[ 87.392332] config string '0378-037a out '

shouldn't the hal_parport config line just be:

loadrt hal_parport cfg="0x378 out "

I tried that and I didn't get the errors, however, I wasn't getting an output to my drivers. I'm using the same settings as my other computer that's right below the bare motherboard I'm working with. I'm rather stumped,
there should be some sort of signal coming out of the parallel port.

Okay now it works minus the Y axis.

I remember reading somewhere within this thread there were reversed pins?
It works with the 8 year old P4, which I'll move into the house to work alongside with the new machine until i get this sorted out.
I thought this was going to be easy, install LinuxCNC, and go. I've used it for a year, and until now have found it effortless to use. But several hours and it's been rather fruitless :/
(Ps the Xyltoex board and steppers do cause wifi interference, I had them on, and it killed the streaming of my sister's phone)

Would be a good idea to read pages 5 and 6 at least

The header apparently has 26 pins (and a parport D connector has 25), seems that the wire picked out in red you would expect to be No1 actually sits on the No 26 pin.

Pins 4 and 5 that supposedly go to the Y axis are causing me issues.
I'm not sure what to do since they should be correctly pinned out.



STEP X PD0 2
DIR X PD1 3
STEP Y PD2 4
DIR Y PD3 5
STEP Z PD4 6
DIR Z PD5 7

Maybe the easiest thing to do is simply purchase a PCI card for a parallel port?
In theory it should work right now, but for some reason it is not.

I think the cable is bad, or a few of the motherboard's header pins are dead.
Therefore I'm going to solder in the A axis as the Y axis, and see if that works.
