New from Old / Re: The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)

So over the last few days I have checked all 96 input lines by temporarily connecting them one by one to 24 volts and using the PLC inbuilt diagnostic tools to display them on the monitor.

Still a bit of a pain, and involves a lot of walking as the terminations are on one side of the machine with the control panel on the other - and yes it's a long way walking round it that gets 'old' very quickly. Still two days spent and I've convinced myself the ALL the input are working fine - now there are several unused inputs but I decided to test them all:

Perhaps the summer heat has got to my brain but I've decided to resume testing to try and get this CNC lathe back on it's feet.

A full re-load of known good software still gives me several very odd error reports from the PLC inbuilt to the Sinumerik CNC control so I decided to step back a bit and do some basic hardware testing:

The PLC has 96 inputs (24 v Active 0 V Inactive) and 32 outputs of 0v or 24v. Up until now actually testing these is a physical pain - they are presented at the top of a rack with five cables terminated in 37 pin Sub D connectors - all tightly lashed together.

However a nifty 37 way Sub D break out board turned up on eBay with male and female connectors and a terminal strip allowing me far better access.

Little known fact Joules. An ordinary screwdriver can serve as a milling cutter.

Owning a round column mill builds character.

A round column mill is the mother of invention.

Steve, where do you get those fancy cutters that can do draft angles as in your photo ???

It can be confusing these new fangled mills that don’t spin off a decorative pattern on the final pass.  Huh, and people pay a fortune for a rose engine….

If it doesn't have a round column, I don't know how to use it.

Yes Steve, I like the uncomplicated things!

Latest version of this Zon Banger uses a 12 volt battery, has timers for time day, of week, periodicy, set back from dawn and goodness knows what else and loads of flashy lights.

No flat batteries with mine !
