help please
« on: September 18, 2008, 03:59:09 PM »
Hello everyone , I have started using mach3 for about 2 weeks and am getting comfortable writing my own code but being a novice I need a bit of help..... :-[ . in the pictures below the motor mounts have some curvy lines . can anyone give me some G-code examples of what to input to make an arc instead of a strait line going from point -A to point-B

these are two motor mounts that I made last weekend for my RC boat that I uploaded to youtube

Peter,

First thing you want/need to do is get something that can generate a DXF file, this is what I use and it's free:

Once you have a DXF file it's really easy to let software make your files, I've been having good luck with Sheetcam TNG, which for the time being is free from Sheetcam.com and has no limits to the number of lines of code.

Kristin ;D

G2 or G3 will give you an arc, have a look at the G Code list for info on the words you need to use with them.

Hood the g2 - g3 inputs I already knew I just wanted an example of how a line or two of code would look like to get an arc or helix from point a to point b . once I have an example I can run with it

Kristin I will download that and give it a buz

thank you
