58" part on a 15" CNC router.

Shows how I setup my Kleinbauer "7th Sojourn" home-built CNC router to cut out a long X-axis brace for a Joe's 2006 router build. My 7th has a 15" X travel limit so I had to break the Autocad drawing for the brace into 4 15" parts. In this video I use a touch-off plate, setup a jig, and run each part on Mach3. Cut is made with a 1/8" 2 flute carbide end mill at between 20 and 30 ipm. Material is 1/2" MDF. Spindle is a RotoZip.

I am currently cutting out the same part (X Axis Torsion Box Long Run Brace) for my machine. I am using my school's CNC which has a 35" X axis so I decided to break the CAD in half rather than in 15" segments.

Nice! You'll be able to cut the a lot of the parts, like the X axis torsion box pipe supports, in one program with 35". Is your machine wide enough on the Y axis to cut several parts at once?

[sbthomas15]

Great video, a very clever procedure and excellent work on the home made Z-Touchpad. What diameter bit/bit type are you using?

[aolshove]

Thanks!  I used an 1/8" carbide 2-flute flat mill.

Very informative explaining in Detail the process. I would love to find out how to program and make the touchoff device for zeroing the Z Axis. Is the touchoff program available in mach3

Youtube won't let me post links but you can search Artsoft forums for "Set Z to zero automatically?Auto tool zero questions" and look for the macro code by Scott Worden.

if i was u i would cut out that design 1 time on the cnc get a router and clamp that under the real board drill some pilot holes and cut it with a hand router it would do each cut in like 20seconds but if you never need the template again its a waste of mdf board

Nice!  I especially like the touch off.

What kind of RotoZip did you use and are you happy with its performance?

I just got the plans for this machine and hope to begin my "sojourn" soon.

[sbthomas15]

yeah the Y is 30". So I was able to cut out 4 of the X-Axis pipe supports at once.

Then you have to configure Mach3 ports and pins to enable the "Probe" on pin 10. The most difficult part was using the Artsoft Screen4 program to drop a button and 2 DROs onto the bottom of the screen and assigning the button click to the macro code (by Scott Worden)
