I have a Weidemann C2000q CNC punch with Fanuc Op-B controller. When referencing the machine will set both X and Y axises (or at least it appears on the display that the position is correct) but then nothing happens. Usually it would ref X then Y and then turret and then auto-index station. Has any one any information on what the machine checks in order for it to complete the Zero Set routine so I can narrow down where the fault may be. There has perhaps been an issue with low temperatures and referencing in the past but this should be affecting it now. Any suggestions at all would be greatly appreciated. Thanks in advance.
