Say what you want to, but anyone here with a memory longer than a couple of weeks knows that's a lie.

Hell, you did it twice in the last month that -I- know of. Somehow, Mach was involved....

You do only ever seem to show up here when Mach is involved though.

I can't really go back through the logs and count because the last several threads all disappeared, the last one for having two...

You know, I am sitting here putting together a Flickr page of random shop pics for curious people and then this. But you aren't curious, are you? You weren't as overtly obnoxious as usual so I...

Ah. Using mainly Artcam, but use Artcam (Delcam) and Solidworks. Don't have a website, don't make things for retail so I don't really need one.
Make all kinds of oddball stuff lately, as business...

What exactly is it you guys are wanting to see, anyway? You can always just ask me, too...

If its threaded into the body, back it out the way you back out any stud; double nut it and put a big wrench to it.
This is why you replace studs after each use on things like cylinder heads and...

I have no clue about Supercam, but I have been using LinuxCNC (the old EMC2) recently, and its pretty amazing nowadays. Its come a long way, now very well supported and with a lot of features. The...

Remember, the software to run the g-code on the mill, and the design software to help generate the g-code in the first place are two very different things. Especially if you are doing 3D parts.

...

I can't imagine that is going to affect anything. It doesn't affect the flatness of the mating surface nor reduce by more than a trival amount the surface area of the bearing surface.

If the...

I use a peristaltic pump. Normal pumps die, even if you filter the coolant really well there are still abrasive contaminants. The great part of peristaltics is that the pumped fluid never contacts...

That's a good point. I have wondered about that myself, as one of my machines is off in exactly the same way, though not by quite the same amount, as it takes a little over 4" of travel for mine to...

LOL, no! Sherline mills are meant for model and miniatures makers. They are very well made (or at least used to be up until a few years ago), but so incredibly light as to not be usable for anything...

Ballscrews have advantages, but reducing backlash isn't really one of them. It often increases it, actually. Especially cheap rolled ones, especially if you have just one nut. If reducing backlash...

Shhh. It may be true, but its still not a good idea to feed the trolls. Don't take the bait is the is the best advice. He is just trying to get a rise from us. (This guy has all of 20 posts to his...

He can get anything he wants, it won't do him any good until he can learn fundamental machining practices and basic G-coding. He sounds smart enough and motivated enough that might not take much...

Very nicely done sir. I have debated about doing just exactly that in that past, as I never liked the way it adjusted either.
I have never got around to pinning it (I just wound up cleaning the...

I would suspect this is common to everyone, but at least for me I usually spend way more time figuring out and making the fixtures for a job than I ever do cutting parts. I find the mill vise is...

Yes, they have a very positive mating surface between the ridge above the threading on the spindle and the top of the toolholder. it goes all the way up and stops there, its not like the collet nut...

Toolholders can be very accurate, as they should index on the flat, not on the threads. You can easily preset a bunch of tools for the same height and use them in exactly the manner you suggest.
...

If conventional left steps (from pulling the tip of the tool into the work), and climb left major chatter, you can guess deflection of the tool is certainly an issue. Bad finish on the work, but it...

Conventional versus climb may show a difference for you, as would coolant, but not using those extra long mills will help a LOT all by itself. That's likely your main problem. You look to have a hell...

I think what they are probably referring to as 'fake' are those systems, that while are indeed technically have a closed-loop, are ones that have no provision for actually taking any corrective...

I would concur. In another thread I was suggesting that I would try to run the cut at 10k rpm and 40 ipm (the same chip load), but you were worried about getting it running that fast. Try the 5k and...

there is no way a taig can run a 4-flute mill of any size and get good finish, especially a small one. i have a 24k rpm water-cooled spindle, and i still use 2-flutes.
you may want to consider...

LOL! We had an old PDP-8e in our basement, it had been replaced by the 'new' PDP-11/24 by the time I got in there. Still have the paper boot tape for that thing in a box somewhere...
I do recall...

Both the G540 and the Mach license are way cheaper from Keling Inc. anyway, on top of their being known for being a very reliable and reputable dealer.

Several people have had problems with the...

I understand the other systems that are out there for the factory stuff, I should have specified for home/hobby/small business CNC it is the best option for us, as we don't have the options given to...

Nope, the name was specifically 'parallel', as opposed to other ports which are almost all serial, from the other ones of the time in 1970, right up to USB (Universal Serial Bus) of today.
The...

There is no way to interface other than through parallel port. Plenty of new machines still have them, and its is cheap to get a parallel port card if they don't. They were designed solely for doing...

You could CNC brass blanks for the machine so as to engrave arbitrary designs with the equipment you already have. If you want actual 3D profiles on the insides (not recommended, BTW), I have seen it...
