I am trying to bring a 1990 VF1 back to life. You guys have all been a big help on a couple things so far! Thanks.

I was unable to work on the machine for a couple months and when I got back to it there were new problems:
There were multiple over heat alarms and 203 Lead Screw CRC error.
Also the machine will only move with jog handle at one speed, regardless of which speed I set it at.

I have not had any low battery alarm and there is 3V at the back up battery.

I solved the over heat alarms because the parameters had somehow switched, low battery??

It seems like reinstalling the parameters would be a good start now.
Do I need to get those from Haas or is there another source?

Thanks-
Chuck
