The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
awemawson:
Adrian the ParcelForce man brought my RS Components order of the extra illuminated DIN 43650 sockets for the three extra ones I'd 'discovered' the other day, so I set too with enthusiasm. Now these devices are tucked away in a dark and difficult to access corner. First original one came off fine and got replaced. Second one was obscured by a hydraulic pipe - no big issue, slacken the fitting and rotate it a bit out of the way. It was when I was disconnecting the cables on this one that the light bulb went on. Hang on, these are wired differently, the cables don't go to terminals 1 & 2 they go to 1 &3 - what gives :scratch:
Well the answer came along with a hot flush - these are PRESSURE SWITCHES not solenoid valves :bang: My excuse for this plonker moment is that they are in a dark inaccessible corner.
. . . off came the ones I'd done, and back on went the originals, and I crawled away to give my pride time to heal :lol:
The good news is that yesterday I obtained the Beaver Manual for this lathe, and also the detailed manual for the SMCC card as PDF's. The Beaver manual is not hugely informative, and unfortunately the drawings of the turret are for the Baruffaldi version, but never mind there is some useful stuff in there.

I dusted off the GoPro camera and filmed the machine moving X & Z axis's and doing tool changes - a little diddy program I wrote just to see how you enter code into the controller and exercise the machine a bit.
I think that maybe the issues I was having with the turret were caused by stiff oil seals - with a bit of use it seems to be getting better. I still can't drive the spindle as the field coil current driver hasn't arrived yet.
Not sure why I'm getting that 'fish eye' distortion, I've probably set the GoPro up wrong, I've not used it in over a year.

Looking good.
GoPro's do give a fisheye effect, it's just the way they are.
Thanks for the info about the turret. I've got an idea brewing, that involves something a bit bigger than my Denford Cyclone, but still fitting under the existing roof of my workshop, as I make some parts that would really benefit from a lathe with live tooling. Just need to get another couple major projects done and running first.
awemawson:
I tried altering the field of view of the GoPro and shot a walk round tour of the lathe - not sure if it's any better :scratch:
awemawson:
The cable marker 'flags' and an appropriately fine 'Sharpie' marker are now here, so I cleaned off the sticky mess that was the previous labels and applied the flags.
Useful exercise, as I unearthed another pressure switch that I had treated as a solenoid, so that's probably saved a few hours of fault finding !
