New from Old / Re: The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
« Last post by awemawson on July 10, 2025, 09:47:01 AM »
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 !

I like the fact that it's an all-mechanical mechanism powered by the gas pressure. It's a refreshing change from the Digital Everything (D.E.) Man, my wife's new Honda just went completely dead, because one of its 16 modules went crazy. Nothing wrong mechanically with the car, but it turned itself on overnight and drained the battery down to 5 volts.

Mechanical stuff like your crow popper. How simple. Brought back to life with pieces of real material put back into it.
