The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)

You are probably right Steve - whatever it is it's doing my head in !

Well excellent news today. Logically I thought reverse the last step and re-replace the 6SC 6100-6B00 card. No - very similar symptoms - X axis going upwards and growling - more head banging. I then took a VERY close look at the wiring and the various connectors that bring signals on and off the board. I then realised that there are two cable forms terminating in 20 pin headers that are both labelled X311 and are bundled together.
Surely not - no - did I put them back swapped - OH YES I DID :bang:

Reversing the error I'm back to "no unwanted moves upwards" on reset - phew. These cables are from the feedback encoders from the X and Turret servo motors no wonder it didn't know what it was doing. Fortunately their pinouts and voltage levels are identical so no lasting damage done.
Still got the green error light on the Go card 6SC 6100 6B00 BUT using my bodge on the error input line 404 I can jog X & Z in a controlled fashion.
OK lets put the original Go card 6SC 6100 6B00 back - oh ho - green light out system ready and I can jog X & Z without doing the 404 line bodge
Hoo blooming ray :clap: :clap: :clap:
Back indoor to absorb the relief with a nice cup of tea and quit while I'm ahead !

Yay!!! :thumbup: :thumbup: :thumbup: :clap: :beer:
(I'm guessing the labeling was not your doing, Andrew, nor that it will stay as such!)
:ddb: :ddb:
awemawson:
Too true Steve on both counts!
More definitive labels will be applied tomorrow, meanwhile I've progressed from the "nice cup of tea" to a glass of "Famous Grouse" scotch with a modicum of ice so I'd best not do it now :bugeye:
