I have an interesting issue with my Gecko 540. I've been cutting a lot. A lot. No issues. Well, since I re-tuned my machine to run a bit slower and increased the latency in LinuxCNC. Until yesterday. It would get about 1/3rd of the way through the cut and then the entire machine would stop (save the router, which is manually controlled). The red fault light was on on the Gecko 540, meanwhile LinuxCNC was still outputting G-code, thinking the machine was running. I re-zeroed and tried the cut 4 more times, all with effectively the same problem, fault. The first two cuts (same g-code) went flawlessly. Hitting the e-stop button and re-setting clears the fault on the G540. I can jog the machine through the area of the fault and not have a problem. Wiggling wires shows nothing.

Setup is:

Gecko 540 Rev. 8
EZ connectors: EZ-G540 - Set of 4 - Soigeneris.com
HobbyCNC #23-130-DS8 stepper motors (Stepper Motors | HobbyCNC)
Dual core 2, 2.4ghz, 4gb of Ram, LinuxCNC v2.5, EPP enabled in bios.
Charge pump enabled.

Thoughts?
