Anyway, at work there is a Fagor 8025 CNC controller connected to a refitted Pratt & Whitney Tri-Max XV milling machine. It lost it's battery and settings, and while I have already replaced the battery and recalculated most of the settings, it still doesn't run. According to the older employees at this company though, it was wired correctly and operated up until a few years ago when it's battery failed.

There aren't any errors shown, but whenever I put it into Jog mode it basically freezes up- not only does it not move, but it will not return to the operating mode menu unless I force it out of Jog by tripping the emergency stop.

In addition, this particular control seems to flatly refuse any and all input other than it's config data, including downloading by RS232 via DNC, direct program entry, and manual jog mode. Whenever I try to input to it, it freezes up.

It's been bugging me for a while now, especially because this afternoon I will be working on a General Electric MarkCentury ONE connected to a Bostomatic 312 mill with a second spindle and W Axis.

That one also has frozen up on entering Jog mode before and is in a similar state as the TriMax, also having lost it's batteries and settings. I've already replaced the batteries and approximated the settings again, though I need to get more fuses for it, apparently it got fuse-robbed during it's downtime and only two fuses in a bank of 12 are still present- likely the last two are the ones that power the controller. Three phase 480V powering it, there are four fuse banks for the four different axis on this machine, and right now only two are present- completing the phase to the control box I presume.

Is there a hidden setting somewhere to make these run again? Or am I just missing something obvious. Not only does the Fagor not accept axis-input instructions or commands to home or move, but it won't let me edit a program or recieve one via RS232 DNC.

And the General Electric I will be working on more this afternoon, it definately needs those fuses to work right but shouldn't be hanging like that.
