A CNC newbie question: Why can't the serial output from a Sargon or similar DRO be fed to a computer then used to control a servo motor on a vertical mill?

Chain and sprockets are non-linear.

Yep - I've received stuff that contained references to Alan Trest and afogassa. I don't know if this means the virus emails originated from them directly, or from a computer that has their email

Does any one have a shopbot that could supply some pics of the Z axis. I`m doing a plasma table and need to make a cheep Z . Thanks Djld98370@...

Someone on this list has the latest virus. The "g-code test" and various members names keep arriving here. RichD

This may be a stupid question, but why not to use a normal bicycle chain\sprocket combination for driving an encoder? Is it a backlash issue? Alex

I use autocad for making my dxf files, things are a lot better now than when I first started but Id be interested to know what you would reccomend in the way of CAM software, free is what I like,

Backlash shouldn't vary by direction. It can vary at different points on the machine depending on wear. John S. Posted 8.50 GMT after post #51631

Not at all. Think about it. Hint: consider the same length nut in each case. Regards, Hoyt McKagen To prevent virus propogation, don't put this addy in your book Belfab CNC -

Brian, Actually, I'm somewhat of an expert, and the reason for a multi-lead screw is this. You want a nut that will advance 1" in 4 revolutions, but if the shaft is fairly small in diameter,

I do not have IBM, but if you go into the BIO's of the laptop you need to see what mode the port is configured for. Take a look at the one that works vs the ones that do not work.

Hi, I am ready to begin adding a DRO to my G4003 lathe. What is the current thought on the best method to accomplish my goal? IIRC, when I was looking into this before, the linear strips from

Saw a couple of caps at Austin Electronics in Atlanta. 100,000uf at 60VDC, 85VDC surge for $20.00 each. I know some of you have been looking lately. www.austinelex.com Regards, JJ Be Kind, Be
