In the past Mach had been very stable for me, but I'm seeing some weird behavior I can't explain. It's the same computer as before, and I'm using the current lock-down version.
Here's what it had done lately.
I was using Mach to run a program and my spindle didn't turn on when the S word should have triggered it. The machine drove the bit into the work. I repeated this several times. I restarted Mach and had the same result. I shut down the computer and restarted it, and then Mach worked perfectly.
Last night I was running a simple drill program. I homed the machine setup the cut, and hit cycle start. I got a soft limit warning. This was odd, as I was nowhere near the limits of the machine. I looked at the part origin I had set moments before, and the origin had moved in Mach. So I re-homed the machine went through the entire cut setup procedure, and it Mach did it again. I restarted Mach, went through the same procedure, and Mach did the exact same weird thing. I then shut the computer down, restarted it, went through the exact same setup procedure, and then it worked perfectly.
Has anyone else seen this kind of strange behavior?
I threatened to change to Centroid Acorn, and I think the Mach Gods are pissed at me. (I really don't want to spend another $465 and learn another system.)
This was the latest program:
