Have you tried right clicking on the setup program for AutoCAD and running it in compatability mode(under "properties" after right clicking)? its worked for me a bunch of times when I tried to

Matt & others; can you provide me with some examples of inexpensive systems like Flashcut [since I've been considering purchasing on of their retro fit systems.] thanks Owen

Here's a site that gives you the some info on RS-274D, which is the standard for most numerically controlled machines http://linuxcnc.org/handbook/gcode/g-code.html Hope this helps --- B Snowden

Lee: I've been doing some preliminary work on this, and it's like a lot of engineering problems in that optimizing for one variable makes another one squirt out. But there's some promise

Tim, I presently have no $ invested in any equipment other than the mill. Why would the servo/G320 scenario be better for me. Marv Frankel

Hi, Brian: No, I'm using the $160 three axis driver kit. This uses LS297/298 chips. I'm running in 1/2 step mode (i.e. the steppers are 200 steps/rev but is being run at 400 steps/rev). --

Seth, If you have enough space on the hard drive, you might consider creating a dual-boot computer, or call AutoDesk tech support, and ask for a solution. Marv Frankel Los Angeles

I think you have it figured out... It's expensive, it must be good! Matt

Can anyone point me towards Books or web sites that explain and give example of G-Code ? Thanks Bruce

Bryan, I wanted to point out something I found out about voltage. I am running CamTronics board with the L298 driver, driving 23 frame motors at 90oz. I have a Power Supply that was feeding 38v

nema 34 stepper, running with gecko's, running 10:1 reduction reliable at 200 ipm (scary, but reliable) so 200 ipm /3.9 (30 tooth 24 d.p. pinion) *10 =500 +- rpm, moving a 800+ lb gantry. Erie

With XP you can run AutoCAD 2000i Zafar

Sounds like I was thinking of someone else's project. Seems to me the sizes I have heard used successfully with a mill that size is 800+ in/oz. I would probably want to use about an 1100 in/oz motor

The new Camtronics drive is built on the new Allegro 3977 chip. Tim [Denver CO]

Bryan, The motors are higher voltage than ideal if your goal is high speed. They will sure make a workable setup, just not the fastest on the block. I agree with you that virtually all the low cost

life milling It's the machine that is simpler. Think of a turntable (like a lazy susan) with the part mounted in place on the turntable. The rotation is C axis Now place a single horizontal

Jerry- Very good! Is this the $400 driver on their website? Do you know what driver chips are used? Are you using full, half, 1/4, or 1/8 step mode? -- Bryan Mumford Santa Barbara,

Tim I seem to recall something about there being a difference in the function of these g-codes on this side of the pond from the way that they are used on the other side. Ray
