I just made a new Gcode file using ventric 2d. When i load it into mach3 the whole thing is shrunk left to right. looks fine in Ventrics but does not work in Mach3. I am VERY new to CNC and Mach 3 so any help is appreciated.

Hi Magicman,

Try this test piece.

If it does not come out square then you may have your steps per unit incorrectly set for your X or Y axis or possibly your X and Y Scale DRO's are not both set to the same value (typically 1.0000).

I used a g0x24 and then measured with a tape and it was acurate. I will try the file though.

here is the file i made.

Did the test piece, I posted the code for, come out square ?

Yes i tested the code and yes it gave me a square within a square 3.75 x 3.75 (with a 1/2 bit)

Then it appears the problem lies within your Vectric layout or the Vectric GCode generation.
Which of the Vectric post processors are you using ??

I doubt it's a Cut2D issue. A screen shot would help, but the code appears to look OK in Mach3 here. All of Vectric's products write good code 100% of the time.

Magicman, can you post a screenshot of what you see in Cut2D and what you see in Mach3?

Just a thought are you using the correct post processor??
