Um, no, that HP 7800 SFF has *terrible* latency - it will spike up to 133,000 after 20 minutes or so. Based on Kirk's recommendation I bought the same one on ebay and installed LinuxCNC 2.7 but the latency was really bad. I tried turning off every power saving features in the bios and all the tricks listed in the LinuxCNC wiki without success. If someone has information about what can be done to fix the latency problems on these machines I would really appreciate it! So far this machine is basically an ugly door stop.
