As if I wasn't stressed enough today, while I was gone to buy some lumber, we had a power failure that lasted 3-4 minutes. My machine wasn't running, but the computer and the controller were running. I have been keeping them running so I wouldn't have to reset my x & y axis zero each time I change projects.

A few minutes ago, I finally got out in the shop and turned the PC on. It won't boot up. It stops the boot sequence and displays the following:

"Ubuntu 10.04.4 LTS probotix-dekstop tty1
probotix-desktop login:"

I have no clue where to go from here. I typed in "admin" and it then prompted me for a password. Now I am stuck again.

I don't know if this is a big secret or what, but I could use some help with this login. Apparently the power failure screwed everything up. My wife said she heard a boom. Later we saw a couple of bucket truck working down the street about 2 blocks away so I figure a transformer blew in the neighborhood.:frown:

EDIT: I called Probotix but they are gone for the day (weekend).

A couple other options that I am seeing it to try this at the command prompt.
type startx (then enter)
If that doesn't work, Ctrl+Alt+F7

Try these at your own risk, just some things I found on the web. None of these should cause any harm.

so far I have managed to change directories. I am in the linuxcnc\configsys directory "ls" displays the files. There is only one and it is in Blue. I guess that is an executable...PROBOTIX

Not really. startx generated some action, and some errors and then it said "closing log, giving up"! ROFL!

When I rebooted, it came back up to the log in screen. but logging in still got me no further than to the command line.

Looks like I will be down until I can talk to Len or one of his guys.

Thank goodness, the machine wasn't carving anything.

If I get a chance tomorrow, I will look into it more.
BTW, if the only reason you are leaving your PC on is because of the possibility of losing your xy zero locations, don't.
They are written into a memory location and will still be there after powering down. You still have to home all, though.

We get short blackouts fairly often here, so all my desktops are on uninterruptable power supplies. Didn't buy the cheapest ones so I get 15 minutes or more of operation to shut down if needed, but usually the power comes up very quickly. No help on the boot up, but I haven't had a crash in years.

I leave my computer on all the time too. Will shut the controller off. Also leave my main desktop in the office on all the time too. It's been on for 7 years.

After reading this Mike, if I ever get one, I may be inclined to put a UPS on the computer and controller .
I never would have thought a power outage could cause such a dang headache .

To think we threw some UPS units away from work as we were updating equipment:(

Have to have a pretty good UPS system if you plan on using on the controller too. Some of the machines run a 220V 3phase spindle which probably isn't feasible. Even for a 120V router.. For the PC itself, yes, but if power goes out while running the machine, that's a whole other problem.

I was wondering the same thing , if your providing power for the controller, your providing power for the router?

In my case I would use a spindle . So I could dedicate the UPS to the computer and controller , and not the VDF .
But if the power went out , the spindle wouldn’t be rotating , which would create another issue , and a bad one at that. Well unless there’s a way to tell the system to pause till the mainline powers restored

On the Probotix machines that use a 120V router, you have an internal relay in their controller, but you have to supply it with external power from another source (just for the router). If using a 220V spindle, then you only get start/stop and speed reference from the Probotix controller, so your 220V source is totally separate.

So if you want to keep everything running during a power outage, it could be more complicated than a simple UPS.

This could be very problematic in our area, as were plagued with brown outs. And it’s not out of the question for a bird to land on the primary next to a pole with its wings spread out , shorting out the grid and blowing a fuse
