Thank you, Tweakie.

The Motor Tuning definitely seems to be the problem.

Once the GCode has been loaded into Mach3 the Toolpath tab shows the Program Limits (size of my border or distance between markers) I then, if necessary, adjust the X and Y Scale DRO’s (main screen) to get the size correct (just a simple calculation required here).

Tweakie.

Thank you for the reply, the original circuit board in Eagle is 38mm x 38mm and when it's loaded into Mach3, it also shows 38mm x 38mm as the program limits (unless I'm looking at something wrong), Either way, I added 4 drill holes at each of the corners of the board and ran just the drill file to show what's happening (please see the screenshots in the links below). When finished, the circuit is only 28mm x 28mm.

Also, If Mach3 is properly seeing the program limits of 38mm x 38mm, does that mean the GCODE file is correct, as peter suggested it might not be?

Thanks again,

Chris

Hello, I'm having a problem with milling a circuit from within Mach3.

I have created a basic circuit in EagleCAD 6.5 and exported it using PCB-GCODE for use with Mach3. The problem I'm running into is the circuit is being milled at about 70% of it's original size -- the overall circuit is being reduced in size.

I have Mach3 setup in millimeters and the exported GCode is also set in millimeters. I have checked over all my setting within Mach3 and everything is set to what the manufacturer of the milling machines suggests it to be for Mach 3.

I'm not sure what I'm doing wrong and any help would be appreciated.

Thanks, Chris
