Sorry for the late reply - this is of interest to me, I would like to run
Linux (Ubuntu or whatever) on my Mac, running it through a parallel port
card
Have fun

In EMC 2.3, you will be able to unhome an axis or all axes.
You would think that a jog override for soft limits would be nice. But then

I use the MSD542 drivers with EMC2 with no problems, (but I don't have
access to my ini file at the moment). The data sheet from
www.motioncontrolproducts.com is a bit terse. I used the data sheet from
http://www.kelinginc.net/KL-5042.pdf, as I think these are identical
drives.

Yes I agree.
I might rename soft limit to safety limit. You should

This is currently how override limits (for jogging off a limit

Hi,
I stuck 3 PCI parallel port cards into my pc. Without any work at all
I could print from two of them. Very neat and I am assuming because they
will print I can attach those for extra I/O.
But the 3rd card was not a parallel port, as you only get three total,

I remember reading somewhere that you could have homing switches and
travel beyond the homing switch. But even better would be to change
the limit switches such that you do not loose 3 inches.
Or just create a second machine configuration with manual homing. I've

I am just working on the RTAI kernel at the moment under Ubuntu 8.04.
Unfortunatly the last patch was on a 2.6.20 kernel and so I have to work

My plan is to setup 2.6.24with a rtai kernel for a x86 and then port

Hi Jason,
I don't think you want that.. at some point (but details elude me) there
has been some majour restructuring in the ppc/powerpc tree.
I think you will find it easiest to just start with the stuff RTAI has
support for.
If you want to give x86 on Hardy a spin, join the devel list.
Anything you can add will help others speed past this part of installing and

The so-called pci_8255 driver in emc is *only* for the futurlec card
with 3 8255 chips and a tiger-320 PCI bridge. It will not work without
modification on any other type of card. (and according to user reports,
not even that card works when any of the ports are set to input mode)
