Agreed, try just swapping over the firmware and see if that fixes the
problem. I suspect it will be something simple like this, are you sure the
parallel port is setup ok?

As a follow up on the discussions of the Intel D510 motherboard, I have now
received my 7i43 board and successfully connected it to the motherboard. I ran
pcisetup.exe from PICO systems to set EPP mode, (if I don't do this then EMC
exists with an error relating to EPP mode - as expected). EMC

At present I'm waiting for my 7i43 card to arrive and so I am interested to
see what happens with the parallel port issue. It seems that is can be
forced to EPP mode however, Ubuntu should detect the available modes - a
bug?

The 7i43 really fits my needs in terms of I/O, cost and from what I've
learnt over last few days, performance. I am a LINUX novice so I not sure
how difficult the EPP issue is to fix, if its a case of running a .exe to
force EPP mode then OK. If its a case of rebuilding EMC by myself then I'm

Hi Everyone,
Here is some info:

Many thanks for all your help and comments, I think I'll try booting from a

Try reversing the sign of the INPUT_SCALE parameter in the AXIS_#
section of your .ini file. I used this to reverse the direction of my
steppers i.e.
INPUT_SCALE = 12000 0 turns clockwise
INPUT_SCALE = -12000 0 should turn anti-clockwise
Hope this helps.
