I powered the mill up and on the control sceen I got load master like always. Then I noticed I had the cable plugged in for G-code programming instead of the one for conversational. So I powered down and plugged the right cable in, powered mill up again and got a ERROR#ox| (the symbol after the # looks like a fish symbol). The manual says ERROR 0-4 I think but no symbols. Does anyone have any ideas what happend. Only thing thats was diff. was its sat for about 3wks. while on vac. but thats about it.
