It's Alive!! It's Alive!!! (Insert Maniacal Laughter Here...)
« on: December 09, 2009, 02:55:56 PM »
I *finally* got off my lazy butt and built a quill drive for my BP clone, after doing X, Y and the knee about 18 months ago.  It uses the same servo motor as the other three axes, driving through a 2:1 GT2 belt drive turning a 20mm diameter, 5mm pitch ballscrew.  Before doing any tuning of the servo (and it's WAY off right now), it's already capable of over 200 IPM, and showing WELL under 0.0005" backlash.

Ray,
Looks like it's a winner. I have thought about doing similar to my Atlas but also want to use it manualy.
At least you had some meat to attach to as the Atlas head is rather small.
LOL,
RICH

Looks good Ray

Better take that handle off before it clunks you in the head, then again might knock some sense into you so maybe best leave it ;D

Hood,

If the handle ever hit my head, all it would do is break the handle....  :-)

Thanks,

Servo motor is the HomeShopCNC.com 850 oz-in, with 500-line encoder.  Driver is a new Gecko G320 (G380X).

Cool, Ray. Looks like you rolled your own instead of using the "future commercially available quill drive" you talked about one time, or an Elrod.

Now, I'm looking forward to your solution for using the knee for tool length comp and the quill for most machining. Maybe with Mach3 v4 at the same time!! Then I'll do mine!

I've got the commercial one sitting on my work table.  I had my own almost complete by the time it showed up, so never got it on the machine.

The tool length comp is pretty easy.  It's not possible to do as I want with Mach3 v3, but Brian and I will make sure v4 allows it to be done properly.  In the meantime, I will create M-macros to take the place of G43 and G49, so I can get it going.  This will be very easy, and functionally just fine.  I should have it going sometime in the next week.
