X & Y screws mounted. Scratch one more "to-do" off the list.

Great work Sam - at this rate it will be making chips in two weeks   ;)

Yep, If I could have 2 whole weeks to work on nothing but Dixie, it might be possible. Unfortunately, I don't see "Dixie chips" (hey, that's got a nice ring to it :) ) in my 2 week future.

A bit more done. I think all I lack now is making motor mounts, then I can temporarily hook up the electronics, to see some movement. Man, that head is HEAVY. Gonna hafta find a source for some lead shot to make a counterweight. 150+ Lbs I would reckon.

"Dixie Chippin' " might not be in two weeks.......but it sure won't be as long as it has been !
Looking real good there Sam !
The mass and rigidity will definitely work to your advantage.
I like it !

That machine has virtually been milled out of the solid.  ;D

Nice work Sam.

Yep, pretty much! It's been one billet machined after another. Finally got 2 motor mounts made this weekend. I'll be glad to see some movement soon... I hope. All this work being done, and it seems like there's no real progress. I need to see something function, #@&%$! Next up is making the mount for the spindle motor. Gonna hafta do some cad work before I can start on that, though. Fitting that large of a motor on such a small space is proving to be a challenge, to say the least.
More pics, but unfortunately no video yet.

Still no chips yet, but more progress. Made the stand (well, part of it), and attached the spindle motor. The stand will house all the electrical, and coolant tank. Will probably have drawers or shelves too, for storage. There will be four more vertical post, (2 front, 2 rear) giving more support, and dividing the electrical, coolant, and storage compartments. I ran out of material, so it just didn't get done this time around. Took a short video of the roadrunner/coyote code running. I bumped the feed up 200 ipm. I tried it maxed out at 270ipm@45,000hz, with the acceleration maxed out, but the gecko's didn't like that. >:D With the acceleration tweaked, 300+ ipm would not be hard to achieve at all. That's about 200 ipm more than what I need, or want, and at the first sign not having enough torque, I'll be incorporating a drive reduction. The Z axis motor did not seem to show any weakness at all lifting the 130 pound head at 200 IPM. I was quiet shocked at that. Still gotta find me a good (cheap) source for some lead shot to make a counterbalance. All in due time, I suppose. http://www.hillbillyhilton.com/vid/DDvid.wmv
