Hi all

I am using a DragonRise USB board set up  to drive various linuxcnc functions.
When I turned off the computer 6 months ago everything was working. Now I have turned it on, the inputs are working & the connected output pins are working but the software does not respond.

So....
input.0.abs-x-is-pos is the USb input (which lights up) connected to halui.axis.x.plus (which also lights up) .The machine is homed but the axis does not move.

I am using QTDragon on linuxcnc 2.9.3 on Debian. I have a second machine that I have not used for a while that is doing the same thing.
Is there some config type thing that I am missing here?

Attached are the relevant files

Thanks
Alex

It seems you don't have a parallel port at all.

Are you using an old computer with onboard parallel port or a new computer with PCI card?
 


and I did try using the parallel port tester but i got this
user@linuxcnc:~$ halrun -I -f ptest.hal
Could not open command file 'ptest.hal'
halcmd:


 

You have to open the Terminal Emulator in the same folder where your parallel port tester files are. For this, right click somewhere inside the folder then "Open Terminal Here".

But with USB to parallel adapter it wouldn't work in anyway. Find a good parallel port PCI card and try again. Avoid any WCH chipsets.

You have to buy PCI card adapter with Sunix, Netmos or Moschip chipset.
 

Okay thanks a lot for your help. I will get them asap. Appreciate everything you responded

Another PC with another of the Sunix PCI-E cards, no warnings on startup, notice the lscpi result where it clearly states the driver in use. This is not near me, a friend i am teaching CNC got this PC and card today, and it works out of the box, well after disabling secure boot in bios as that would cause permission denied and seg faults!!!
Now we need more test systems to figure out why the driver loads on some systems and does not on some...

I have a old PC donated by school and I have a parallel port connected to PC with a USB adapter. Since this PC doesnt have a parallel port connection.

This is the connection. Parallel port from bob, port to usb adapter, adapter to pc

Please keep it civilized.
Thank you.

I would ask them how LinuxCNC is supported.

If it's directly supported with their Ethernet interface
they must have sample configurations/drivers for LinuxCNC.

If it's only supported via the DB25 connector/LPT port
then you would need a PC with a parallel port or an Ethernet
to parallel device like the aforementioned 7I96S or similar.

In that case , it might be easier to just use whatever control
software that is compatible with their Ethernet interface.

Yes it is my driver
Is whitch of these ways is your stuff connected?

 

 

The first one, active low, theres jumper in pul+ DIR + and ENA+

Go to "Applications" (upper left corner), then "Terminal Emulator"

Copy the first line, paste in terminal, press enter. Then copy the result or take a picture.

Do it for the remaning commands. One by one.
When i paste the second command it asks me for my password but i dont know why i cant type anything.
 

 

Just type it and press enter. It just looks like nothing is happening.
