I'll be out for a while, but if you will post your gcode file as an attachment maybe someone can load it and compare.

Hi, Ron

Theres a way in Lathe to Fix this sort of Arc problem, Looking in Mill now, Haven't found it yet though.

Thanks, Chip 

Your file loads fine hear for me, It's a I,J issue in Arc's, What Post processor are you using.

Here is the gcode.

Thanks

Ron

Go to the Config menu then General Config and change the IJ Mode to Inc, that should cure your problem.

Hi, Hood

It was right in my face D---u-h---!!

What's the G-code for setting "Jog mode" for "Cont", "Step" Mode while your at it, More------Brain------------- Fade

Thanks Chip

That worked. How about "Motion Mode" should that also be "Inc"?

Thanks alot. Ive had this problem for weeks & I was going crazy.

Ron

Last post should be "Distance Mode"

Ron

I think it will depend on your code but I would think Distance mode would be Absolute.
Hood

Thank you guys very much.

I cant tell you how this drives a person crazy.

Dont know how it got checked Absolute. I loaded Mach3 on the laptop & it was checked Inc.

Thanks again

Ron

Hey,
Was gone for ThanksGiving weekend, just  got a new computer after 5 years...my P4 3.0 kicked the bucket

I found it on ebay:

-Intel Core 2 Extreme QX6700 Quad Core (4 processors!!!  )

-Asus Striker Extreme LGA 775 SLI ATX Motherboard

-EVGA NVIDIA GeForce 8800 GTS Video Card (Swich this out for a Nvidia Quadro 1400 PCI-E 16X)

-Two 750GB (1.5TB) SATA II Hard Drives (Raid 0)

-4GB PC2-6400 DDR2 RAM

-Dual 20X DVD Burner

I can OverClock @  3.744 GHZ  for each of the cores at a 3663 FSB :O...my feet are getting alittle warm thou
(Haven't OC it thou)
...like running a Core 2 Due @ 14.976 GHZ

I would not suggest the Asus Striker motherboard...unless you have alot of time to set things up on it..without breaking it.
Great for 3d modeling CAD/CAM work, but since everything is so new alot of Driver and software updates every month.

I would suggest running this computer in 64bit to take advantage of the 4gb ram...

I'm using a AMD64 3800 with 1gb RAM and Nvida Quadro 1400 PCI-e 16X to run Mach on my machine.
