Default Independant machine comparison

an administrator at the college of design at minnesota university has prepared this side by side comparison of cnc machines in his search for the right the right equipment for his curiculum, i felt it is noteworthy as it is well done and accurate.

Cool very cool, I think the men in yellow and black look good in a side by side.

Thanks for posting my research to camheads James. I am liking the yellow and black Joey, I may try to get to Columbia for the Aspire Camp to see it in person. Is there a Cobra in MN's Twin Cities or Western WI, I could have a look at?

Can somebody here give me the X, Y, Z footprint of a CR 408 and the Z travel on the 12" clearance machine?

I got a quote from MultiCAM today so added it to the matrix:
https://docs.google.com/fileview?id=...ZjA3MzIz&hl=en

Though I suspect there may be a slight bias here, I welcome any/all feedback/comparisons etc.

This machine will be used in a collegiate fabrication shop in design education: mostly by architecture students. Rhino is the most widely used 3D design tool here, so we'll probably use RhinoCam for toolpath generation. Output will include 3D topographic site models, 2D building elevations, modular building systems (tab & slot), molds for thermoforming, occasional furniture parts and surely a million things we would never have thought of.

We're currently considering (in no particular order): Precix Industrialplus, Techno LC, ShopBot PRSa, CAMaster Cobra and EZ Router Scorpion. To me these machines (except maybe the ShopBot) have very similar specifications and capabilities. Pricing w/12"z, 3-5hp spindle, vac table and vac pump ranges from $26.5k to $37k. The Techno got about 10K higher than the sales rep initially indicated which may knock it out of consideration.

I would very much appreciate any comments and suggestions, particularly useful would be significant quantitative and functional differences between the machines.

Obviously part of the cost and expectations with such an investment are support after the sale. Comments regarding the customer service, maintenance issues and user support networks associated with any of the machines/manufacturers are also appreciated.

If anybody notices obvious errors or can help fill in any blanks on the table, that would be appreciated. I have not included a couple of manufactures of whom I have requested but not received a quote(after 2+weeks). If there are other machines that NEED to be included please let me know.

Thanks in advance, I hope input from this knowledgeable community can help us determine which machine best meets our needs.

Regards,

in my experience cnc owners are self flattered that we can actually run these things!! many of us did not recieve any formal training in this and so we depend on each other heavily, hence the comaderie that comes from forums.

to the camaster owners there is a post here worth noting and an interesting poll

http://www.sawmillcreek.org/showthread.php?t=135809

i will note there are thousands more blue owners out there so in shear volume the quanitative value of a poll may not reflect todays available technology. in addition while another brand may have tons more owners one must remember that 90+ % of those owners are hobbiest and smaller machines, with camaster all machines are fully welded industrial based machines of the same quality thru out.

welcome to camheads

KG, The foot print of the frame is in the attached pdf. The gantry over hang can change depending on your needs. we have been building the Cobra line with the overhang (cantilevered design) for the Recoil Included so this would make your machine's total width @ 75" in the X - Also take in to consideration of the plumbing and the control box adding 12-13" to the total length (Y) of the machine.

On CAMaster CNC Routers our normal set up for orientation is:
Across the gantry is the X, the length of the table is the Y.

I have an older Tool Changer 510 in Lakefileld, MN just South of I-90.
The machine is on its 2nd owner and is gray not yellow. And is about 3 years old. The customer is running Aspire.

Thanks for looking into CAMaster CNC Routers,

I found a revised side by side from Kevin. He added more machines for people to compare. :)

There is a good bit of info here. And I think the boys in yellow are looking good side by side with the big boys.

I'm in total agreement with Jim on the following quote.

"In addition while another brand may have tons more owners one must remember that 90+ % of those owners are hobbiest and smaller machines, with camaster all machines are fully welded industrial based machines of the same quality thru out."

I've spent years on the other forums dealing with the hobby mentality. That's in the rear view mirrow. The pro's need a place to share their efforts.

From everything I've seen the Camaster is a superior machine in every way. The main issue for this company is the blue folks have a head start. But quality always wins out.

Greetings every one,

I've taken the liberty to post the Univ. of Minn. CNC program on the 3Dsignforum.com giving Koodoos to Camaster.

http://design.umn.edu/current_studen.../hall/cnc.html

I haven't seen much university interest with CNC's until now. Don't be surprised to see more college offerings.

Happy Routing
