Ditch G28!

Previously (somewhere earlier in this blog IIRC?), I managed to edit the post file to enable me to define an X & Y home position for the table. I didn't want the table to return to the true machine home which would be miles out of the way. At-Man on Youtube had posted a video explaining how it's done, so it seemed good timing indeed and I set about it. With a little help from him, I got there. 

So now I find that G28 doesn't work the way I want it too - in the Z axis now. I've messed about with it for quite a while now and it's clear that G28 isn't going to be a goer. Instead, after each operation I'd like the quill to return to the top of travel (G53 Z0) so that I can use the power drawbar to do a tool change. On the face of it, that would "simply"(?) require me to extend the mod to the Z axis.

But it's one of those days. Even making an identical copy of the current, functional post file, I find that it crashed when I try to post with it. WTF????? This isn't happening. I haven't even change a thing - apart from the file name itself, yet the error complains about a variable not being defined.

Nothing's easy....

TIG welder up and running - after some fault diagnostics and repair

Finally got some time to connect up the flow meter and argon hose. Plugged in the torch and ground cables and the torch hose etc. Powered it...
