Topic: y axis screwy

Just had a breaker get thrown, apparently killed power to the computer and solidoodle.

Brought everything back up and noticed that the Y axis is now only traveling about 1/3 of the way from front to back.  X and Z axis seem to work ok. 

Any ideas of what to do for this?  Did the eeprom settings get fried?

Thanks,

Did you home the axis? What happens when you try to?

When homed, all the axis go to their proper locations.

After shutting everything down, then turning it back on again, pressing the reset button on the solidoodle board, and resetting the eeprom to factory settings, I was able to get it to work again.

Now the only problem is that it isn't quite centering the print.

Interesting. I was going to suggest you restore eeprom. Presumably your y-steps were off. Did you happen to notice that in repetier the printer thought it was at the y-max even although it only got to 30%?

The electrical issue may have caused freak charge that affected your eeprom which is quite volatile to static. I know that the idea of the circuit breaker causing a specific issue for one eeprom value sounds ridiculous, but I've seen weirder magic when it comes to IC chips...I don't question things as much anymore.

I've seen power blips scramble single EEPROM values before as well.

That's exactly what I saw, the printer thought it was at y-max but it wasn't.

Cool! That's basically a confirmation of the diagnosis.

It was great right away when you got it to work, but find it also satisfying to know what happened [often the fixes come without explicit answers]

Are you still having problems with the center? And what do you mean by "center"?

I had to reset the y offset so that it would center the print around the center of the bed.  That seems to have fixed it.

OK! Good, so you figured that all. Boss.
