General Mach Discussion / Re: Defining material, 0/0 point, etc.

Hi Frank,
It’s all good but don't hit the "Ref All Home" button just Zero each DRO's then hit "Start".
If you are using a "V" bit then you may wish to consider V-Carving for your lettering. There are many commercial softwares that generate the correct Gcode for doing this but there is a free software that may also be of interest to you - http://www.scorchworks.com/Fengrave/fengrave.html
It does a pretty good job and I have used it for some quite large signs with great success.
Hope this helps,
Tweakie.

I cant find any information in the manual for defining material size, setting a "home point", 0/0 point... even when I look at the screen and see that Mach3 is starting dead center on the graphic, and I manually move the spindle to dead center on my chunk of wood, bring the spindle down til the point touches the surface, hit the "Ref All Home" button so everything is at "0"... when I hit the start button the spindle moves to some strange and exotic location before it drops and starts the routing process... nowhere near where my mathematical, Type A mind thought it was going to go.
