Henning:
I can't wait to see some parts produced, but in the meantime, the sheer awesomnes of your project keeps me on my toes :clap:

Impressive!

vtsteam:
After this tremendous project, the first parts produced are probably going to be the cranks for a small manual lathe!

:lol: :lol: :lol: :lol:

So just to prove I've not been entirely idle a little bit of a progress report:

(Times been short, since my last post I've built and tiled a porch and a gas bottle store, repaired a 'post knocker' for the tractor and put in 100 metres of stock fence, done a few trips to the abattoir - and occasionally escaped to the work-shop).

I decided that one issue I ought to be able to fix relatively easily was the 'X Axis Overload Trip' error. I had already proved that the proximity sensor for this was indeed giving an output, so the error report was genuine, and if I fiddled the output electrically the report was cancelled. So the task was to expose the sensor and see if either the sensor was faulty or the overload clutch had tripped. Easy to say, but the X axis assembly is a huge enclosed lump that holds not only the servo motor for the X axis drive, but also the rotation drive for the tool turret, and also the motor that powers the active tooling in the turret. All this is enclosed in tin work to keep coolant and swarf at bay, and is swathed in screws (why use so many different head styles :( Three hex socket sizes, slotted screws and bolt heads!)

Eventually got the covers off:

To expose the innards:

Can you see the sensor?

No - nor could I !!!!!

I could feel it, I could see it and the overload clutch using a mirror, but only by climbing inside the lathe and standing on the swarf conveyor.

Clutch had not tripped, but sensor was loose in its clamp, had rattled too close to the bit of the clutch it had to monitor and hence had given the error. Quick tweak with an allen key and error now cleared - only took two days of odd hours to get at it :med:

Still it's IS progress :)
