I'm working on a new MM quietly in the corner #5 - Orlando. FL
 
Greetings MM fans.
...pending my final dwg exchanges and release of cap rail modifications that are graciously being checked/verified by Gerald, I will start my build in the next couple of weeks. Of course, I have to get accounting to agree to let me spend company money! :) So, it might be month or so.

Parameters of build:[list][*]5' x 10' net cutting area[*]8" channel main beams[*]Architectural Alum / Hardened steel cap rail rail system[*]Gecko 203V drives[*]G100 controller (what the heck....sounds like a great challenge!)[*]Mach 3[*]PK296A2A-SG7.2 geared steppers (chosen to match 203v inductance per the forum)

Current projected cost's are $6818.32 US plus labor, plus tax.


Pictures and such will commence during the build.

See ya'll soon.

Sean, I think you are going to do very well! Well, . . . . . welcome! :)

Richards Sun 07 October 2007 20:07

Sean, check the Gecko forum on Yahoo groups for some information on the Gecko G100. The Rabbit controller is failing (without cause) on some units. Mariss has contacted Z-World, but an acceptable solution still hasn't been found. (Neither my G100 nor my G101 have given me any trouble, so I'm hoping that Z-World may have just had a batch of flaky modules.)

smreish Sun 07 October 2007 20:17

Mike,
I was following that thread as well. Thanks for being on the look out for me. My biggest concern was a few folks were having a big issue with the rabbit module a few months ago and loosing the tcp/IP connection and unable to reset the firmware. The most recent threads from Mariss seem to have fixed that issue. I really would like to use the G100, but I might just K.I.S.S. for now. I haven't purchased the Gecko components yet.

Thanks in advance.
Sean

Sean, It feels like you are having a great time.:D

what did you do for the main power switch ?

I see that the design shows a switch mounted on the rear panel, but the operator is to be mounted in the door.

switch
 
Dave,
I will din mount the 40a rotary switch on the rail and then match the mating half on the swing door in front. This is a very easy installation and will look very similar to Geralds MM control cabinet on the MM home page. If you want a quick look at the specs...AutomationDirect.com 40A/3pole/ with 200mm connecting rod and operator.
Sean

driller Wed 17 October 2007 05:58

Thanks. I had seen the AutomationDirect unit when I was looking.

I have used DPDT relays rated for 10A before on my other units. (not MechMate).

Making Progress

Hello MM fans.
To date - everything for the kitchen project is ordered and I am anxiously awaiting delivery of Gecko's, Oriental motors and drive enclosure. I have made many runs to SKYCRAFT Surplus (yes, you can visit them online, but I have the luxury of going to their store and rummaging around the bins!) Anyway, since I am waiting for things to arrive, I decided to draft the table layout to verify all my steel dimensions and sizing for shop fabrication. Note, I am making the table as a "gated" perimeter w/ the spoil board purlins bolted in place. Since 3" channel is readily available in my shop, I have substituted it for all the pipe in the lower setup. I have attached a quick little doodle for review. Sean

Gerald D Wed 17 October 2007 21:09

See you have drawn it symmetrical. Remember that the router/spindle is likely to sit offset in the y-car and this has a huge impact on the table symmetry.

Those extra crossmembers between the legs may get in the way when you consider the symmetry issue, or when you maybe want to put in vacuum table piping.

smreish Thu 18 October 2007 08:47

What is the offset?

Gerald.
Nice catch. I was working from dwg 10 10 310 for the elevation of the table support legs and such. This appears symmetrical. What I don't see, is the offset distance for the channel -spoilboard- offset dimension. Did I miss it somewhere in the package? See drawing for location in question.

gmessler Thu 18 October 2007 08:58

Hi Sean,

I spent some time looking for it as well. I finally found it in 10-10-300W. 3.9"

Good luck with your build!

Greg M

smreish Thu 18 October 2007 09:13

Found it
 
Greg,
Thanks for the quick reply. Yep...found it at the Centerline of the table. I see the 0,0 corner shift of 3.9" (100mm). Gosh - that's plain as day!

Gerald..if it was any clearer, I wouldn't have missed it :)

Of course, I probably shouldn't be drafting at midnight either!
Thanks.
Sean

Gerald D Thu 18 October 2007 10:19

The non-symmetry comes from having the router/spindle sitting next to the dust hose. Blame the dust hose! :)

Spoil board & Table revision

Gerald.
Thank you for the observations. I have revised the doodle for comment. I have moved the spoil board by 3.9 inches and adjusted the leg base for future access of vacuum table - which I will install asap.

Just like all good designs...you have to go back to the original to get it right!

....note, almost all of kitchen table project is in. Waiting on enclosure and motors to arrive, but I have everything else on hand. The shop started cutting steel for the gantry yesterday.

Sean

Gerald D Fri 19 October 2007 06:14

That's more like it!

There is a cyan line in the front view, just under the "purlins", running x-direction . . . . . does it mean anything?

smreish Fri 19 October 2007 06:20

Gerald.
No, errant construction reference line that is on the wrong printing layer. It's now turned off. Oops...drafting mistake. :)

I feel like Steve Martin with a new phone book!
...Just checking my layout with all the parts and enclosure. Finally, UPS delivers the goods!

Regnar Mon 22 October 2007 16:41

Sean I was wondering if I could come and check out your build when you are done. I am over in Tampa and frequent up to Orlando for the theme parks. I have never seen a large cnc in action and would like to pick your brain and have a good look over the machine. I'll even bring the beer:)

smreish Mon 22 October 2007 18:33

Russell,
You or any of the MechMate community may come by my facility at any time when the build is complete. As I mentioned to the forum, I am building quickly. The steel order went in today! Controller is in fabrication. Hopefully, I will be done in about 4 weeks.

Sean

Regnar Tue 23 October 2007 15:15

Thanks Sean, One month is alot quicker than my timeline. That would put you around Thanksgiving time for being finished. Goodluck and I'll be watching the thread. Russell

Sean what do you think you have so far into the project money wise. Its amazing what acouple of phone calls can do as far as price goes from one shop to another. Tried to price all the steel today but I think I have to go in a little more educated for the type of quality and hardness.

smreish Tue 30 October 2007 13:24

Steel is cut!

Steel all cut and laser parts in. Looks like I will have a busy week in the shop!
Gerald, you may notice the 45 degree angles on the small channel. I was able to optimize my yield with that extra 2" per cut! Now it's off to de-scale the steel before clean and marking. Sean

Russell,
To date I have spent 5K and only have the rack and pinion left to purchase. So, All said and done, I will be right at $5,500 with a complete 5x10 machine. That includes the *new* computer, screen and software.

Regnar Tue 30 October 2007 17:28

Not bad at all you should be able to earn that back in no time at all. Where were you able to save the most from your projected budget?

smreish Tue 30 October 2007 18:40

To date the big $$$ saves are as follows:
"new computer" $142 with XPpro (I had an extra 17" flat screen monitor at the shop)ebay
K2Router Mount $50 ebay
IGUS chain $120 ebay
Wire and control box electrical components - skycraft surplus (about $500 savings) *they are local to Orlando, but can be reached online.
Steel on hand (did not have to purchase 2x4 rect tube or pipe)
Mach3 license on sale at CnC4Pc for $139.00
Use ground MM rail option and NOT cap rail as previously budgeted (about 312.00 savings)
So, in summary - being thrifty and shopping on Ebay saved me about 1K in total.
