LazyCam (Beta) / creating contoured z paths
« on: October 11, 2011, 03:39:26 PM »
I've been using lazycam and mach3 for the past 2 years or so for milling with a router but I'm trying to develop a new approach and don't know how to achieve it with LC, or if it's even possible.

I don't know the correct verbiage to describe this, but I'd like create a "scoop" out of wood; curved z contours. Instead of just plunging the router in to a depth and dragging through the wood, I'd like it to slowly ramp down in z value and then ramp back up as it moves x and y. Basically an arc in the z direction.

Does LC have the capability to do this?  If not, what does?

Thanks much

General Mach Discussion / lazy cam to mach 3 - loss of drawing integrity
« on: September 09, 2010, 04:17:24 PM »
First time poster on this forum.  Apologies if this question has been addressed.  I looked in the FAQ's and poked around a bit.

I'm starting my mill file in Autocad, importing to Lazycam and then opening the g-code in mach 3.

My file in Lazycam looks great.  It looks exactly as I drafted it in CAD.  However, when I open the g-code in Mach 3 I lose a lot of the integrity of the original drawing.  For example, some arcs will become giant circles, or if I have two lines ending close to each other Mach 3 will connect them, much to my dismay.  I've had to do all these work-arounds, actually changing my CAD file through trial and error to get Mach 3 to perform as I originally intended it to with my CAD drawing.

Is there a setting or tolerance I need to adjust in either Lazy cam or mach 3?  Is there a thread about something similar someone can point me to?  I have a pretty good feeling this is all user error, but I'd like to learn how to fix it.

Thank you.
