I am still using my original Tormach controller from 2010 for my 1100 Series 2 that now has Series 3 drivers and steppers. I upgraded it to Path Pilot in 2015. My Tormach order for the upgrade shows that I got it for a PCI slot. However, I just looked at some pictures I took of my controller at the time to determine if it was PCI or PCI-e and it looks like it is a PCI-e expansion slot.
My old controller only has enough USB ports for the keyboard, mouse, and one for the remote input for programs. With PP 2.0 out I am thinking about getting a new controller for more USB ports and for reliability. My controller has been stable since I had issues with booting after the original PP upgrade in 2015... I was thinking now might be the time to upgrade the controller and put the original controller on the shelf as a backup. If PCI-e is better I would have to buy a new board as well.
I use a fourth axis and a Rapidturn as well.
Is there any advantage to having a PCI-e interface vs. a PCI for the 1100 or will I never notice the difference?
Thanks for your insight,
