Joe's Hybrid - Xnaron's Build

[Xnaron]

I've got a build thread going on the Joe's Forums and I am going to put a mini thread here as well. I've been wanting to build a CNC router for at least 5 years now. I've finally got all the other projects out of the way and have started on my Hybrid build. I've got everything ordered sans a few small items. Here are some pictures of some of my components and the start of my table.

Controller/Drive will be made of the following components

-54V 1000W power supply
-4 x Gecko 203V's
-PMDX 122 BOB
-4 x Hobby CNC 405oz-in Steppers

I am in Canada and it was fairly expensive to get everything that I needed from the US. I did order expensive Stepper Drivers (Gecko) and they cost me $800+ CAN. I have ordered almost everything and my total so far is $3800 CAN. I have budgeted $4500 - $5000 CAN.

Will add more details later...

Cool, cant wait to see how much it'll end up cost a fellow Canadian, I will probably be doing to same machine soon I hope, but might use the 540,s with 425 oz steppers, would save about $500.00, I don't know if it would make a diff from the 203,s you are using with the smaller steppers, maybe some one can tell me. Good job so far. Graham

I'm looking forward to watching a fellow Canadians build both here and on Joe's forums.

Can't wait for more build progress.

Looking good! You are off to a fine start.

The G540 needs motors with Bipolar parallel inductance of 4mH or less that require 3.5A or less. What 425 motors are you planning to use?

I have the xylotex 3 axis with the 425's that came with the drivers, but ill need one more motor I guess. Graham

Looking great man. A few of the parts have me interested. What are the bolts pictured with the bearings. Looks to be 8 of them. They seem to be smooth on the outside with a whole down the middle. I'm thinking they go with the bearings but I'm not sure.

Also, I see you have a ton of llittle rectangular aluminum spacers with a hole in the center. What are they used for and where do you buy them?

The Z 425s Need 90 Volts to develop best speed in Bipolar Parallel. Your rapids will suffer if you use this motor with the 50V G540. You COULD use one on the Z axis though.

A better choice would be the Keling KL23H276-28-4B or KL23H284-35-4B.

Those are concentric and eccentric bushings. The eccentric bushings are used to adjust the tension of the bearing against the raik, The rectangular spacers are actually steel unistrut nuts. The are used for attaching pieces of unitstrut together.

Thanks for the info Mr Reamer, ill look into the Keling drives, seems like some good products there.

Hey Xnaron, I was wondering what drive screws are you going to use, Are you looking for speed. I,ve been using 8 tpi 4 start for my little Solysylva and I'm getting over 200 imp on my Y axis, so it,s something to think about. Seems the only place us Canadian,s can get them is at rotons, but there good priced. You do lose a bit of resolution but with your drives it should be ok with 10 micro stepping.

I am using these 10 TPI on the x and y http://www.mcmaster.com/#98940a020/=qxwwo and these 8 TPI on the Z http://www.mcmaster.com/#98940a623/=qxxr9 They are the black oxide upgraded with higher hardness and tensile strength rating than the screws that are on the Bill of Materials for the machine.

I bought them from a member of Joe's forums. I just received them today. I should be able to cut comfortably at 140IPM with these from what I have read. I would rather have accuracy than speed but if I could get the speed without losing appreciable accuracy I would go for it. I am on a learning curve with this and am trying to stick to the plans. I am doing a few recommended mods. Tell me about rotons I have never heard of them. If I upgrade my screws in the future I would love to have a source to check out.

Ok just checked out www.roton.com ... they have quite the selection and have the matching anti-backlash nuts to go with the screws. I like the way their website is laid out. Much easier to find things by category.
