Yes a possible scenario. I'll have to contain my impatience until the back end of next week before I can delve into it. I did at least yesterday print out and fix suitable cable labels - the masking tape I'd temporarily used last time was getting tatty and illegible. There are a lot of screw terminals close together in an awkward low down position and to make an error would be very easy. |

All the myriad of house guests seem to be sleeping in this morning so I crept off to the workshop :ddb: The cooling system has been a bit of an unknown - a big lump called a Schroff RHB 3000 bolted on to the end of the cabinet, taking in warm air from the top, and blowing it out cooled at the bottom of the cabinet. Certainly lots of air flow but I wasn't convinced it was actually cooling. I had thought that the whole thing was a factory sealed item, but yesterday when showing a nephew the lathe I realised that in fact it had a totally enclosing cover that could be removed. Hence creeping away this morning to investigate. Taking the cover off let me gain access to a termination box that among other bits houses a contactor - contactor not pulled in, cooling compressor not running! Jamming contactor armature over into the 'made' state with a screwdriver the compressor starts up, and air coming in at the top at 25C is now exiting at 14C ! The problem can only be either one of the thermostats, possibly the contactor coil, or one of the various trip devices in series with the coil, but daren't start investigating now or my absence will be noticed! This may account for the failed X&Z axis servo as it is first in line for the cool air. Anyway - a few pictures a/Over View with cover removed b/Close up of control box c/Circuit diagram thoughtfully provided by Schroff and glued to lid of control box! |

Was there anything on the machine that actually worked as intended? It seems that every part has (had) a fault of some kind. |

I think it is just an accumulation of issues that people have worked round rather than fixed. In the case of the chiller unit it probably failed years ago and no one was sufficiently switched on to notice - in most climates it probably wouldn't matter. Being rather anal I am checking and double checking everything, so probably teasing out things that had gone unnoticed. For instance I asked the previous owner if he had had the x1000 issue with the Automatic Toolsetting - he said he had never used it - yet it is the most useful facility saving loads of time !!!!! |

Some people like jigsaw puzzles. But you only get a picture out of that. Or a Rubix cube, where the satisfaction after solving amounts to finally lining up some colors. Figuring out what a list of brief misleading phrases refer to will be the personal reward for the crossword puzzle fan. Then of course you could spend your time making an industrial size, quality and value, precision piece of computerized manufacturing machinery work as once intended. Not appealing to many. But, nice that it is for someone. With the capability. |
