G11 stepper chatter
Posted 14 February 2010 - 12:02 AM
My engineering friend Pete helped me simulate the conditions a few hours ago. We determined that when the voltage gets down to about 11V that the stepper start to behave irregularly, and they get even more irregular at 9 v.
I could have solved my problem in the field by disconnecting one of my heaters, or using a lower amp heater in one of the applications.
This of course was the SAIA stepper system. Although it is well known that servos often like to have their voltage upped, the fact is that low voltage due to cold weather is probably a "compounding additional factor" for systems that already want more power than humble steppers.

I think the temperature may have had an impact on the battery. But I've never tried to run three c-14 length cords all at once before. Probably should have disconnected one.
