General Mach Discussion / Re: New people welcome !! Come in here and introduce your self!

Hi Brad,

Welcome to the forum and good fortune with your engraving business to come.

The squiggly lines are usually described as 'crop circles' and are related to how arcs have been created in your CAD / CAM (BobCad).

Within Mach3 if you go into Config ; General Config then change the IJ mode that should resolve the problem.

In future your generated Gcode should really include (at the start of the code) a G90.1 (if you arcs are created in Absolute mode) or a G91.1 (if your arcs are created in Incremental mode). The Mach manual describes this in more detail when you get the time

So it just a touch pad then.

What CB script do you have entered into your 'Auto Tool Zero' button ??

General Mach Discussion / Re: How to get rid of offset

« on: November 07, 2014, 08:07:52 AM »

I have this line every single time in the G code.
N140G00G43Z20.320H1

If I leave it, it screws up the Z auto zero after I zero it.

I delete it every time and it's fine. How do I get it to stop inserting it??

I presume you are using a Vectric CAD/CAM - in which case locate the post-processor you are using and delete the codes you do not want to appear in that line.

Take a look at F-Engrave http://www.scorchworks.com/Fengrave/fengrave.html

It's free, easy to use and makes a good job of V-Carving.

Hi GFR,

What exactly is it that you wish to carve ?? (V-Carving, 3D relief, outlines ??).

Perhaps an example of you intended .bmp or .jpg may be of help here.

It would help if told us exactly which tool setup pad you have bought and how you are trying to set it up ??

Perhaps check your PSU output voltage when it all stops - the PSU may be going into thermal shutdown (or something similar).
