Milling stops randomly without errors

hi

I'm new into CNC. Built CNC, set up LinuxCNC 2.7.15 thru StepConf on Debian Wheezy. Clear stock. Homing works fine. Milling works fine sometimes (very short ones). But sometimes it just stops without any errors. After resume F2 -> R code can go further or can't even stop earlier code than before. I can finish a job after couple restarting but I want to know what is a problem is.

I thought it might be "Spindle at speed" problem (my MFD controlled with analog voltage) so i turn it off in HAL machine and custom settings but it wont solved a thing. I haven't changed anything else btw.

Here is a couple of lines where Linux CNC has stopped:
G2X47.687Y30.348I4.225J27.679
G1Z-14.500F300.0
G3X34.961Y85.397I-9.850J0.000
G3X47.211Y75.547I0.000J12.250

Would be appreciate for a help.

Thanks for answering. No errors in terminal. Only message right after stop "task: main loop took 0,221527 seconds"

No warnings or errors.

Can you post your HAL and INI?

Run Linuxcnc Status right after it stops and see what the interpreter is doing.
Machine menu Linuxcnc Status

Copy it and paste it here but use spoiler and code tags please.

Maybe this will give some hints on what is going on. After you post your hal and ini files of course.

Thanks for answering. Here is HAL, INI and log from status.

Thanks everyone. I've solved a problem. Seems issue was insufficient power. All I done is switch CNC box and spindle to other phase than PC (I have 3 phases 380V power).

OK, thanks for reporting back.
