I have not seen any aluminum garbage trucks at all!

I might get in trouble for my excess use of aluminum, but hey, it's easy to work with and I had it laying around. Some updated pictures and the proof that it's cutting. Still need to tidy up some wires and a few things like that, but it is operational. Thanks to everyone's help, especially Gerald's.

Kevin - congrats - so you get the number 22?

domino11 · #35 Tue 17 February 2009, 22:32

Kevin,
Get some decals on that red beast. Looks really good. Congratulations.

Gerald D · #36 Tue 17 February 2009, 23:24

That's a proud dad with his two babies! Well done!

Nice going , just watch that z-plate does not get caught in the rafters

Kevin,

Congratulations on the machine, babies and every thing.

You got to love the Milwaukee!

KevinL · #39 Wed 18 February 2009, 06:08

Thanks. I think the rafters (floor trusses in this case) are an optical illusion. There is hopefully enough clearance to get a vacuum hose in that space. I'm pretty happy with the Milwaukee, this is a light cut, but the wife said she could barely hear it cutting upstairs. Didn't somebody have extra sets of decals made?

I am sure Joe can hook you up. Just PM him. jbmclain

Neat! That's gotta be the shinney-est mechmate around! Looking forward to seeing some cuts!

Kevin,

Gerald has asked that you're build be added to the Builder's Log. At the time of your first post, November 24, 2008, you already had your table built. You said you had been on the Forum for about a year. Could you give me a date when you actually began your build?

Also, please confirm the size of your table. I have 72" X 48".

Regards,
John

I think I actually started on it over the Christmas holiday, so I'd say Dec. 20th 2007. My table size is actually 100" by 56" which would give the 4'x8' cutting area, but I am currently limited to the 72"x48" due to the linear bearings. Does this mean I'm #22?

I've already broke a bit, I guess I better slow it down. :-)

Hi Kevin, the serial numbers are allocated only for those machines that are cutting, painted and have the MechMate logo attached. You are only short of the logo.

Hi Kevin!
Great machine.
I plan to use linear slides like you, how powerful steppmotorer are you using? Which model?

KevinL · #46 Fri 27 February 2009, 20:26

I'm using the Oriental Motors PK296A2A-SG7.2. There is more friction with the linear bearings simply because there is more bearing area, but the motors have no problem moving the gantry or y-car. I haven't cut any big files yet, but they haven't even got warm.

Hi Kevin, would you mind telling us what your Mach motor settings are for the axes?

KevinL · #48 Sun 01 March 2009, 11:12

No problem, but I make no claims at all that this is even remotely optimized.

All axes Steps per are set at 3666.93. Velocity and acceleration on X and Y are 300 and 20, and Z is at 120 and 4.

Are there any other values you'd like to see?

Gerald D · #49 Sun 01 March 2009, 12:50

Thanks Kevin. Your accel is similar to those with V-rollers, the speeds are slower, but that is personal preference. I wouldn't say you took a performance hit because of the linear bearings over the V-rollers.

blurrycustoms · #50 Thu 26 March 2009, 09:58

That is a great looking machine, and great color choice

luizfrds · #51 Thu 02 July 2009, 17:28

The Linear "Rails" are a great touch, with dimensions they are? 20mm?

domino11 · #52 Thu 02 July 2009, 21:21

Kevin,
Did you ever get your labels on the machine?

anton · #53 Wed 15 May 2013, 04:37

Hi Kevin,
Could you post a video on youtube of your machine running. Would be great to see!

Best,
Anton

I don't think Kevin lives around here anymore since his last post was 2009

.
But maybe he wakes up out of hibernation, who knows. I would be interested to hear about his experience with the linear rails as well ( since I have gotten SKF linears for my X for next to nothing, and am in doubt on upgrading the entire machine if it's worthwhile)
