What software would be recommend?

If you are talking about the 7i25 card. Then I have to say that I have used a few of these with no issue. I have also had a lot of success with using PP pci cards with Lcnc with much issue.

You are correct that if two motors need to be homed to set the gantry square each time, then at this time you have to use the dev. branch (2.8) to do this. If that is not required then the best version is 2.7.12

I was just unlucky but pci is getting rarer of course ethernet is more future proof.

I had 2 machines that wouldn't boot with the 5i25 and then the 3rd machine wouldn't boot dvd or usb only cd so couldn't get latest linuxcnc on it. Then the last machine I tried had no pci slots only pcie so in the end I bought another pc for £10 from a local recycler and it worked fine.

On the linuxcnc forums I was told that there is a boot issue but it affects less than 1% of computers I just got unlucky twice but I have 2 RM education pc's from the same seller on ebay and when I checked they have the same motherboard although different cpu's.

As a matter of interest what bob are you using with the 5i25. Is it the 7i76?

At the moment got it connected to the cheap $5 PP bob but I've ordered 7i76 to swap over it might take me a little while to swap it over as it works lol.

My biggest issue is I'm stalling when cutting anything over 5m/min so I think I need to get 3nm motors for the X&Y, I only have 2nm direct drive, I have 10mm pitch ballscrew on now.
