PathPilot PC Hardware

What PC hardware does the Tormach PathPilot have? I'm wondering what motherboard, cpu, ram, video card, hdd...etc they chose. It's probably a good reference design for those looking to build a new linuxcnc machine.

There's a thread on this subject over at cnczone.com (unless the recent spam attacks have taken them off the air...)

4 motherboards listed as compatible are:

• Intel DG41AN
• Intel DH61DL
• Gigabyte GA-H61M-S2PV
• Gigabyte GA-H81M-HD3

The Intel DH61DL only has one PCIe slot (and no other PCI type slots). I can't find a source now, but I thought I had read a comment on hardware for PathPilot that it doesn't like integrated graphics. The PCIe slot would be used by the Mesa card (the 6i25 in this case if I understand correctly), meaning there's nowhere for a PCI-type graphics card. Am I mis-remembering that integrated graphics hardware can be problematic for PathPilot (or standard LinuxCNC)?

Andy - thanks! Let me throw out some system hardware "issues" that I've come across and please let me know if my understanding is incorrect:

I was going to ask about 32 bit vs 64 bit (again, stumbled across outdated info somewhere that I can't find now about PathPilot needing 32 bit hardware (I need to take better notes)). But it dawned on me that Tormach only introduced PathPilot a year or two ago, and as far as I know, there is essentially no source in that time-frame for 32 bit "Pentium" branded processors, thus, PathPilot must run fine on 64 bit architecture. (Or put another way, any processor that works on the listed motherboards and is faster than 2.7ghz should work fine with PathPilot currently.)

The other thing I came across was SSD vs. spinning disk storage. If I understand correctly, PathPilot doesn't care, but rather there may be an issue with the version of Ubuntu that is part of that install. Luckily for me, I have old spinning disks laying around, and the system won't meaningfully benefit from SSD speed, so I'll just stick with re-using an old disk. If I understand correctly, PathPilot expects the system's drive to be minimum 320gb, and if you want to use a SSD, it may need to be "prepped" somehow but can be made to work.

I'm new to all this, so please correct or clarify anything that's not quite right - thanks!

Pathpilot works fine with any size drive and with ssd's , and really does not care , the mimimun i have used is 40gig hard drives , same with 32 or 64 bit , any PC Capable of runnning Linuxcnc 2.6 or later will run Pathpilot , SSD'S work fine too .

the main problem with using SSD'S is you don't want to be reading and writing to the drive all the time , so some preparation is needed to use them , their are many articles on the net over setting up ssd's .
a lot of previous problems have been overcome in the last 18 months or so , and as Andy says much of this goes for latency too , i never took notice of latency , unless it was extremly high , which tended to be branded pc's at the time .
and with using Mesa cards , much of that goes out the window , with using hardware stepgens etc

I would add to the whole pathpilot video question
A looking at the Pathpilot PC shows it using integrated graphics. now it may not be Intel but it is integrated
you can see this in the pathpilot upgrade doc.

Ah! I found the following: TD10342_PathPilot_Upgrade_Kit_0415A.pdf

on Tormach's website. According to that, #1 in your clipped image is the motherboard's parallel port, which is not used with PathPilot, and #2 is the Mesa card's port.

But as you point out: they're clearly using the integrated graphics off the motherboard! Thanks!

This combo I am currently running PP on. This set-up has turned out wonderful for me and latency around 5-7.
I listed the components in my thread below. Hope you have fun getting everything going!

cncnoob1979 - thanks! It's good to see I'm on the right track. I see you used a 7i77 BOB - I"m planning on a 7i76, which obviously has some differences, but I may bug you with some questions when I get to that. Cheers!
