General Mach Discussion / Can ECP port run G540 with mach3?
« on: January 02, 2011, 10:32:56 AM »
I have a Dell Inspiron 8200 laptop computer. I went through the optimizing and it passes the driver test. Only question now is will it run a Gecko G540? It does not have a EPP parallel port. It only has Normal, ECP or Bidirectional. Is it absolutely necessary to have a EPP parallel port to run the G540 with Mach3?

I have cut Ti every day at work for the last 25 years. We use only carbide tooling because HS doesn't hold up long. In the long run you will spend less on tooling with carbide. If you cut a lot of Ti, stay with carbide tools. HS drills work fine with it. Most of the time I like to grind drills so the point isn't perfectly centered so the drill cuts oversize a little. This goes a long way in making your drills last longer. Sometimes a standard drill will get dull and you will swear it got squeezed down as it gets melted down in diameter. Hand grinding a new drill will give it just enough run out to cut down on this problem.  Tapping Ti is best done with special taps made for it. Standard HS taps don't tap it worth a darn. I wouldn't plan on reaming it unless you use carbide reamers.

As far as catching on fire goes. Thick chips around .002 thousandths thick or better are really hard to catch on fire unless your cutter is really dull. Really thin chips that are like steel wool burn white hot and are easy to catch fire. Same goes for saw dust from cutting it on a band saw. One time we had someone welding overhead on a crane and some sparks got in a chip barrel full of Ti and aluminum dust from the band saws. It burned and smoked up the whole building so we got the day off due to the smoke. Lucky there isn't much to burn in our machine shop. Big parts will not burn. If you ever get a thick block of Ti to catch on fire you have bigger problems than that block burning. That will take a lot more heat than you will make just cutting it. Even getting thick parts say 1" in dia. red hot to braze it won't set it on fire.

Not sure how 303 Stainless Steel would hold up to whatever you would like to make. 303 cuts nice and is much easier to work with.

Thanks for all the info on the controller.

Ok, dumb question answered, I just saw wired ones on ebay. Guess I should have looked harder.

OK, This may be a really dumb question on the controller. First I want to let everyone know that I never had, seen or used any video games in 20 years. So please give me a bit of a break.

Here is goes.

All the Xbox360 controllers I see on ebay are wireless. If there are no wired ones then how do you get it to connect to your computer? Maybe there are wired ones?

I know its been a long time sense you posted about your index mill. Still I would like to ask if you have and pictures of the machine showing how you mounted the motors on it. Also wonder what kind of screws you are using. I have a old index of around the 1940s vintage that I may want to convert to cnc one day.
