Joe's 4x4 Hybrid - my build

[Reflow]

Not as carry-on, but a luggage.

I've just looked back at the ebay listing for the 8020 and noticed each piece weighs 16 pounds, so it's probably too heavy anyway.

Looks like I'll have to wait for the local pricing, which I can guarantee will be a lot more than the $50 to $70 you guys pay over there.

Time to move to the USA!

Cheers,

Claudio

Hey Claudio,

Another option in OZ is Maytec, much the same as the 8020 and minitec. Don't have any idea about comparative price though.

Thanks for the tips Scott.

Actually I got my quote back from 80/20 Australia and the main extrusions are about AU$125 (US$110) each plus about AU$35 shipping for 3 of them and the 125 t-nuts. So total for the lot inc shipping is AU$475 (US$420). I must admit a bit less than what I was expecting, but more than I had hoped for

Above prices are ex GST

Cheers,

Hi BP092, Im very much thinking of building the hybred, what I was wondering is, you say you put about $1000.00 into the drives and motors, you dont say how big your motors are, I was looking at a web site but cant remeber which, but any way they had a 4 axis gecko drive with 4 nema 34 750 oz steppers with extra things like estop,limit switches and a shuttle controler for $2500.00 Joe had said you paid around $2500.00 for your whole machine, Can you tell me what you excpect to get out of your system. speed and torque and such.Thank you for your time and cant wait to see the rest of your build.

Graham, I posted a complete bill of materials in the hybrid private forum for the members there, but went with hobbycnc 305oz/in unipolar motors (4) with the 4 gecko 203vs. My total cost ended up being around $1500 said and done. Machine was easily built for under $2k. So if I had to estimate off the top of my head I would honestly say that I built this machine and controller/electronics for less than $3,500. Again though it is totally do-able to do a regular cnc controller like hobbycnc's and spend significantly less. What I did is pretty high up there. It will provide performance but only if it is something you surely think you see a return on. For example if you are doing this for small hobby stuff, a sign every week or so it's not really worth it unless you have the money to spend. I plan to run the 4x4 hard and get a quick return with just using the machine.

Thanks BP for the reply, $3500.00 aint bad considering you can build 3 hybreds to the cost of 1 4x4 shopbot. This is for buisness so it will be worked hard, My goal is to build 3 or 4 of these machines , not all at once though, Do you tihnk the 305 oz/in are enough for this if your working them hard? Graham

[joecnc2006]

the 305oz/in are uni-polar so if you run them in bi-polar like the geckos do they become 425oz/in motors.

Hey Joe, I have the 425's now, Is that what you are using in your video's, What are the acceleration settings you have on those motors on your hybred, Why im asking is this is a big key in relief carving, at least thats what im finding anyway. I use cut 3d to do my gcode and it would estimate 2 hrs to do a carving but in reality its more like 3hrs and thats because of acceleration. Graham

[joecnc2006]

I used accel. of 15.....

yes 425oz/in in video's with the hobby cnc pro kit.

Here's a short video jogging around at 300IPM. I can jog at 400 IPM and more but plan to run this machine max at 200 IPM cutting 150ipm strong like Joe to not have to babysit it. It runs very strong and smooth, I'm very happy with the results. Should be cutting the dust shoe by midweek.

WOW that looks friggen great, very nice machine, Cant wait to get the plans and start mine. Graham

[Glidergider]

Brian,
Very nice.

[grahamshere]

Hey bp, That is a 4x4 machine right? It looks much bigger than 4x4. Bet your pretty happy with the performance, seems to run very smooth. What speed would you get when jogging both x&y at the same time, Around 600imp I bet.Ill be getting my plans soon.cant wait to see you cut somthing with it. Graham
Oh ps ive watched the video about 20 times now
