Fireball v90 not responding to EMC2

Hi all,

I tried solving this problem by asking on IRC, and although i was pointed in the right direction i wasn't able to find a solution to the problem. This time i thought i'd try the forum as it might be easier to explain via copy-pasting rather than descriptions of whats on my screen.

My machine (link: www.probotix.com/FireBall_v90_cnc_router_kit/ ) will not move at all when i try to home the axis. I was led to believe that it is a .hal file issue. The configuration files (link: www.probotix.com/cnc_downloads/ click on V90 EMC2 Configs) might not be right for my computer setup, and i don't really know enough to know how to correct them. I have installed a parallel pci card, and i need to edit the hal file to point emc2 to the address of the card. i also have an onboard parallel port i don't want to use).

sudo lspci -v gives me this:

The card i've installed is a Sweex PU005V2 if this is any help to someone. Any help with this problem will be greatly appreaciated.

Thanks for your time,
Zammy

Hi,

This line near the top of the V90.hal file:

loadrt hal_parport cfg=0x378

is where the parallel port address is set. 0x378 is probably going to be your onboard port.
You need to change that to either 0xbc00 or 0xc000 as your lspci output shows.
I'd try the first address first and then the next if that does nothing.

thanks very much mozmck! on friday i thought i had to append one of those addresses, not replace them. That solved it! At least partly.
When i try to home the axes now, the motor(s) jitter once - the axis sounds like its trying to move, but doesn't - it doesn't sound healthy at all.
Are there any ideas to what could be causing this?

If your using a lower voltage power supply you might need to lower the acceleration for each axis. It looks like you should be able to run the Stepconf Wizard and open the file up and change it from there. You can also change the parallel port address in the stepconf just leave off the Ox part.

It was another config issue. i must have slapped the keyboard when i was changing the address. i re-downloaded the config and the problem dissapeared. thanks for the help.
