G-Code, CAD, and CAM discussions / Re: G code subroutines ??

M98 P1002 L10 (M98 is the subroutine call command - P*********x is the subroutine name - Lxx tells it how many times)


There is a lot of room between $5000 and ripping B&D off.

The clip and ring were machined in wax on the CNC and then cast in sterling silver.

Thanks for the comments.


Thanks for the complement Brett but I have to say without sounding like a someone trying to kiss up but without using Mach3 I really do not think I could have done this work.  It is amazing for about $160 the capability that Mach3 has.  From the wizards like the helical threading that come with Mach3 to all the G codes and the A axis control it all works seamlessly and without much of a learning curve.


This is a final "release" of the Traveler Pen.  Almost everything I did on this pen was a first for me, threading, modeling, cutting wax with complex toolpaths, Having the wax cast, finishing the sterling silver and a whole lot of time fitting and finishing.

This is a long pen with 112 sterling silver inlay dots, custom made solid sterling silver clip and band, Pomele Bubinga Sapwood on the body and African Blackwood on the cap. Ebonite nib assembly holder along with the top finial and bottom cap.  I purchased the London Stanley compass inset in the very top of the finial and the nib and nib assembly.  Everything else was fabricated, fit and assembled by me.

Close up of the cap front side.  I engraved a sterling silver disk with the compass and then made a fixture so when I heated the disk I could bend it into the proper radius.  I then enameled the engraving with black enamel. I finished with 0000 steel wool.

This is a photo of the pen clip on the rear of the cap.  The clip was machined in wax and sent out for casting in sterling silver.  Once I got the clip back I finished the clip mostly by tumbling and some buffing.  I then used Liver of Sulfur to blacken the clip. 

Shot with the cap and pen together.  On the bottom of the clip in the oval is my trademark df.

Why is the pen so long?  Well I wanted to make it so that a converter would fit in the body.  Again the part I purchased was the nib, holder and converter that you see outside the pen.  I made the threaded black ebonite on the pen.  Outside threads for the cap inside threads for the nib assembly.

But why does putting a converter on the assembly make the pen long?  Well like any good traveler you always travel prepared.   The bottom cap unscrews and you can store a refill cartridge in the back of the pen.  I made a separate storage compartment that is separate from the rest of the pen body. A place to store that special contraband.

Thanks for looking.

What do you want the book for? To build or learn?


Ok, I re-read your post.  I built my mill.  Nice to learn about how things work but a real pain in the butt if it is your first.  I know nothing about lathes but I am going to buy a CNC (I keep saying it but I really will...). Anyhow, I am going to buy the Syil and learn as i go.  Books are ok but if you are going to make only one item you really don't need that much knowledge.

For backlash comp and A axis cutting I use version 1.9 anything beyond that is suspect.

What if you changed the Dir LowActive for Z in ports & pins?

I think I found the problem.  The programs I run have a lot of lines of code.  Usually well over 100,000 lines.  It seems that displaying the tool path takes up way too much system resources and the controller starts doing weird stuff.  So I will test it again later with the tool path display off and see what happens.
