The Water Cooler / Re: Broken CNC milling machine
« Last post by AdeV on February 16, 2019, 01:25:01 PM »Mutter grumble... 
So - replaced all the caps
cleaned up the boards returned and re-wired and things lit up kinda like they should do 
- but no spindle action 
When I powered up this time, the first thing the machine requested I do was replace the buffer batteries... so - whilst I had it all powered up, I did exactly that: 3 shiny new Duracells to replace the ones which are 8 years past their "best before" date. And now the damn thing has lost all its parameters & switched to German! Argh! It's not a disaster, I have the parameters saved on the computer, but buggered if I know how to switch it into English until I find the manuals. Annoyingly, I think the spindle problem MAY be the phases are out of order in the plug - this is the first time I've tried to use it (well, excluding the time it caught fire a few weeks ago), and I recall I had to switch wires in the plugs of both the normal mill and the lathe, in order to fix a phase difference between my old & new workshops...
So... once I work up the Round Tuits to figure out the parameter re-load... I'll have a go with the phase wires the other way around. Oh, and try to figure out why the shiny new batteries have decided not to work properly.
TBH, I'm getting closer to think it's time to re-fit this mill with some updated electronics/controller.

New from Old / Re: The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
« Last post by cnc-it on February 16, 2019, 12:34:17 PM »No problem Andrew. It's just that I had an Hitachi Seiki lathe that used a proximity sensor to position the turret like the Beaver here but it didn't back off and re position on the notch like yours does, it just stopped when it reached a tool position so that got me confused for a while

Our Shop / Re: The is a rotary phase converter question
« Last post by John Rudd on February 15, 2019, 02:40:56 PM »3phase power= V x A x 1.73
Ergo 220 x 200 x 1.73 = 76130 watts....
Your ballpark seems good to me...

« Last post by Alphawolf45 on February 15, 2019, 02:21:50 PM » No way did you overdo the files. .Just very peculiar that you didn't pull them out till now. 
I buy files every year from a couple to a couple dozen and I use and abuse them. It would be fantastic to have that many new files on hand at one time. I grabbed a file this morning that just skated across the steel , dull and needs to be tossed.. I've saved some dull ones thinking I'll forge blades someday but someday never shows up.
