Okay, I've continued running tests and this code works for me:

N100 G00 X0.0 Z26.9875 (start point at beginning of square stock diagonal radius)
N120 G18 G02 X12.70 Z19.05 I12.70 K0 A50 F40
N130...

Okay, I've read over numerous posts on the forum, plus much more information about G02 and G03 arcs. And, after trying to run some tests with both, I'm now thoroughly confused.

I need a simple...

Hi Victor, I know this is an old thread, but I need some advice and help on stationary tool holder like yours.

fordav11 has helped me to understand that my ShopNotes conversion CNC lathe is...

fordav11,

Hey, a great link!

Thanks again for all your help. I'm setting up my tool setter touch probe now, and trying to read all the new CNC material. There sure is a lot to learn and...

fordav11,

Thank you for your reply. I did continue to research and learn about cutting these arcs, and I have finally figured out the I,J,K etc and how they work. But, I'm still confused about...

I'm learning and writing G-code for a Shaker Candlestand centerpost, and I need to cut a small radius - see attached.

I'm running Mach3 in mm, and have converted all the inch measurements over. ...

Victor,

Yes, I DO cut these on my TWO woodworking lathes. But, I have many more intricate turning pieces that this CNC can do far easier and quicker than I can turn them myself. Plus, while this...

Gerry and all,

I just wanted to thank you and everyone else on CNC Zone for your kind help, and to let you know that I have finally developed a quick process to go from 2D DXF to full working...

Okay, after a full day of work with OpenSource CAD, GMAX and the CNC ToolKit, I have finally developed a full design process to go from a 2D dxf to full working Gcode.

Now, I just have to tweak...

Hi All,

I'm a CNC newbie, having just converted my ShopNotes Router Milling Machine over to an XZA setup running off of Mach3.

I am also a newbie to CAD/CAM, GMAX, CNC ToolKit, Gcode, etc. So,...

Just wanted to post this link that I am following to set up my 2-axis (third axis run by old reversible garage motor) router lathe mod to my ShopNotes milling machine.

Chris's project notes...:...

Gerry,

Okay, I'll download Mach3 and use that as a simulator for the Gcode.

I did a Google search on open source DFX conversion to Gcode and found the Ace converter. I'll look for another.
...

Gerry,

Okay, all that makes sense. You say to do this all in CAD, which I'm reading and learning about now. Are you saying that the roughing paths that you've shown can be laid out in CAD so...

Al,

I converted the post.dxf that Gerry provided bia ACE converter to Gcode. I then loaded it into CNC Simulator, but it shows the wood blank being loaded vertically and give a -0.018 out of...

Al,

Yes, I have downloaded the CNC simulator and am learning how to use it now. Once I convert the DXF that Gerry provided to Gcode, I'll pull it into CNC simulator and see what other code I have...

Gerry,

Thank you for all your guidance. Yep, I'm starting off small, but using the example of CNC lathe developed by someone else using the Arduino. The reason why I want to use the Arduino is...

TX,

I am currently reading several CNC books which detail Gcode, as well as numerous internet posts regarding turning scanned drawings into DXF files and converting them into Gcode. But, all of...

I built a ShopNotes Router Milling Machine (a hand-crank woodworking milling machine) and now I am turning it (slowly) into a CNC router lathe with the help of many teachers on the internet.

I...

I built a ShopNotes Router Milling Machine which I now want to turn into a CNC router lathe.

The router platform moves on a 1"-5 Acme Rod and nuts. I need guidance on what high torque stepper...
