Here is the current state of the mill:

The root cause of the issue with the Z axis motor not moving after a while, was a faulty AC servo controller on the Z axis. The support person at Tomatech (where I bought the motor and drive several years ago) told me that the FN14 function on the servo drive, displayed the pulses received by the dr...

Thanks for that. I knew that I'd have to find the root cause of the issue - I was just putting it off.
You provided the impetus I need

A bit more about the Z axis problem, when the Z axis stops moving, the DRO on the Acorn increments and decrements, so as far as the Acorn controller is concerned, everything is normal. The servo controller for the Z axis, however, shows nothing other than its normal display. When the Z axis is worki...

The touchscreen is now finished, there was a bit of work getting all the cables etc to be routed neatly, but I'm happy enough with the final configuration. I got to use my 3D printer to make some custom brackets and PSU holders to fit to the rear of the touchscreen. TouchScreen finished rear.jpg I h...

Here is the latest. I decided to Use Tinkercad to design and 3D-print a mounting plate to go onto the Mill control box, this accepts the connections from the mill's axis etc. Originally I was going to use a DB9 connector for the limit switches, but in the end, because I already had holes and cable g...

Thanks Uwe,
I do write things down, but memory is my major failing.

I used to be a bit of a sponge for information, and when I became a systems engineer (prior to the accident) I found it easy to absorb the relevant training courses an...

Is there a glossary in the CNC12 manual, explaining what the terms are? I think I am slightly familiar with some things, but I probably don't use the correct names for them.
