Alibre can export 2D .dxf files. You need to create a drawing of your part, start with a blank sheet, the export the drawing as a .dxf

Go to Config>Logic, and click the browse nutton on the right side and make sure the path points to Notepad. Is this Win2K? I think the path gets messed up in Win2K sometimes.

Check the port setting. As for the estop, try enabling it and toggling the "active low" setting.

You need a lead-in move, and you need to specify the tool by using P and the radius or D and the tool # in the tool table, ie

G42 P0.25
or
G42 D1

Here's an example:

G40
G0 Z0.13
G0 X0.00 Y2.50 Z0.13
G42P0.25
G1 X0.00 Y3.00 Z0.00 F150
G2 X0.00 Y3.00 Z-0.25 I0.00 J-3.00
G2 X0.00 Y3.00 Z-0.25 I0.00 J-3.00
G0 X0.00 Y3.00 Z0.13

This thread has an explanation that might help.

If you're using AutoCAD 2002 or newer, I wrote a macro that will create your g-code from within AutoCAD, including G41/G42 (automatic lead-ins on circles).

Are there any plug in for Mach 3 that can be used to verify G-codes , just to see mill cutter removing material line by line in 3D; for kind of beginner it is just reassuring to see simulation made on a material before running it live.

Not a plugin, but http://www.cutviewer.com

You can get it as a package deal with MeshCAm for a decent price. www.meshcam.com

Guess I should have bought the one on Ebay the other day for $35. The price is going to go up, now that everyone will want one.
