General Mach Discussion / newb questions
« on: January 14, 2010, 09:47:05 AM »
Hello,
I have built a Solsylva 48x48 CNC mill. i am running it with mach3 and CamBam. This is the first time I have done anything with CNC but I am getting things figured out.

my reason for building the mill is to cut out RC Airplane kits of planes me and some friends have designed.

My question 1:
Is there anyway in eather CamBam or mach3 to bevel the leading and trailing edges of my wings or will I need to get the parts drawn in 3D?

I would like to figure out some way to get the beveling done with my straight bit or a ball end bit. its EPP foam that I will be cutting out of.  the bevels I want to accomplish are like 3/16" down and 1" back on the leading edge of the wing and about the same on the trailing edge.

Question 2:
right now what I have figured out in CamBam for generating tool path cut depths is- i set the final depth inc to .188 for 3/16" foam, my stock surface to 0" and my cut depth to .188". I then zero out to the top of the table and it cuts fine. Am I setting this correct? Is there a better way? I would prefer to zero out Z on the top of the material not on the table top.

Thanks for any and all help

Jon

i am using CamBam to create Gcode for mach3 from dxf files. but every time I try to load the .nc file from CamBam I get extra circles added. sorry if this is a newb question but this is my first cnc. the same files open fine in emc2 but I want to use mach3. any help would be great
thanks

General Mach Discussion / Lazy Cam/ Mach 3 error question
« on: December 22, 2009, 01:09:10 PM »
not sure what the minimum system requirements are for mach3 and LazyCam but I keep getting an OpenGL error every time I try to load a drawing from lazyCam to Mach3. anyone know if I just need a graphics card or is there a setting somewhere that would fix this?

for the record its a Dell GX280 3gh CPU with 2gb RAM using the on-board Graphics.

its controlling a HobbyCNC pro driver board (don't think that matters but just in case)

Thanks
Jon
