Okay,

First a big thanks to Jazz:tup: for helping me work through part of the problem and I think I have sorted it fully but will be doing step better to make sure it is fully sorted.

First a G80/G83 cycle had been triggered that I had not cleared when closing the g-code for the drilling cycle when was running that was giving the strange secondary commands and locking things up in Z motion. The Z axis appears to have been over tuned (my fault) and this so far seems to be what was causing the problem.

I will report back tomorrow on how things progressed and if everything cleared up or not. I have learned today some important items and only broke 2 drill bits so not that expensive (TiN coated HSS). Anyway tonight when I get back to the house will write up the code proper (separate from the mach wizard) and that should allow a full running check on the system.
