Yeah Lol Just go with something bigger. I would love to engineer it but it's going to be more of a "common sense design".

I have a hurricane rated glass exterior door laying outside of my garage...

Hmm..

I'm wondering now how much it would hold up to twisting? I would basically be using it on my gantry just like how it is setup on yours, the only difference there would be is that I'm gonna...

Do you want to sell that 4' 8020 length? I think I wanna go that route for my Y axis.

Yes I am concerned with the tooth contact being only 7, and if there is any gaps between belt teeth and pulley teeth I would think (only from reading about CNC machines) it would definately introduce...

Well I just got my 12tooth 3/4" wide pulleys in from otterconsignments. The pulleys are pretty decent. I'm a bit skeptical on how well they were machined and I'm going to examine them on some 5/8"...

I'v read a few places that people using timing belts usually never have a problem with stretching over time. A couple were plasma cutters and only few routers. I'm worried about stretch under load...

Well shoot you know what. If the 3/4" belt does not hold up for what I'm gonna do, and since I'm getting 25 12T pulleys. I will just leave room on my CNC table to be able to have the option to slap...

Wow that actuator was a deal!


For the heck of it. I just bought a lot of 25 of those 3/4" 12T L pitch pulleys off Otterconsignments ebay store for $33.30 shipped. Even if I don't use them for...

Well, I think I'm gonna follow in your footsteps. I'm either gonna choose a 12T L pitch pully or a 14tooth to carry my X and Y axis belts. If I'm gonna get the 12T I'm gonna go with your choice in...

Hey Tim.

I like your design. Nice job on the 3D design.

I'm now leaning towards the L pitch 12T pulleys. The only thing I'm worried about is the amount of teeth that are going to be in...

I got an email back from Polybelt.com.

They said they are in the process of moving to a new warehouse and their site will be out for 1-2 weeks.

I can't believe it.

Polybelt.com just stopped listing all their open ended belts they had on their website. Why? Wonder if they are updating the site? Are they gonna stop selling open ended...

Ok now I'm looking into 3/8" pitch belt from polybelt.com. I can get 6 x 20tooth 3/4" wide pulleys and 30 feet of 3/4" wide 3/8" pitch open ended belt for $163 bucks. For $182 ($19 bucks more) I...

Are your pulleys 25mm wide? polytechdesign.com doesn't have any 5M 25mm pulleys.

I'm still choosey on the 16mm T5 pulleys and T5 16mm wide belt. I can't imagine 4.5ft of 16mm wide belt not...

Hi all.


I'm really trying to figure out what is best to drive my CNC router table for my needs. I'm mostly gonna be cutting foam at first, but since I'm going this far in building a CNC table,...

So I guess when one of Chai's ebay listing say "end machinings" on the ballscrews that means the ends of the ballscrews are machined to fit the bearing block? (reading that you machined your ends) ...

Man that machine is looking nice!

Where did you get your supported rails? I just ordered 6 supported SBR16 rails from this ebay store > http://stores.ebay.com/linearmotionbearings. I got two...

In the picture below is some type of work I would like my CNC machine to be able to handle once I learn more about 3D cnc machining.


I think in my gantry design, I'm gonna make the fixed Y...

Stangtjk: Thanks for your replies. They are very helpful when I'm trying to figure out what is best to get. I still have to do my homework on what size pullys I need, what size belts, if fiber...

I want to design my CNC table very similar to that. I am trying to figure out if using timing belts is going to be cheaper than ballscrews. At some prices I'v found belts to be $10 a foot and...

Could these rails be butted up against each other to make the overall length longer? Will you guys be supplying any longer 20mm rails in the near future?

Is the $4.99 shipping for as much as you...

Well for $200 shipped you can get the 60" supported rails with 2 bearing blocks on VXb's ebay store. I thought of some how making my own under supports too, to save money but then thought to save...

How are the 20mm shafts without under support? do you have the 55" or 60" shaft? I am trying to figure if I can use the 55" without any supporting rail underneath for my CNC table I want to build....

Thanks for your reply Matthew.

I'm not looking down on the hardware store built CNC machines. Just after a little research on the Phlatpriner I decided it was not what I wanted. I would much...

Hi all.


For the people with CNC experience, do you mind reading my post to tell me if I'm going in the right path for my needs? I greatly appreciate it!


I'm getting all my chickens in a row...

this is what I have in mind for right now....

package: CNC 3 axis Stepper motor Drive system...

I thought about the belt stretching.... but then, I'm only gonna be cutting mostly foam and balsa wood. once I get my table working properly and precise then I will try out some hardwood for...

pong? lol

SWEET! this is exactly what I was looking for! thank you!!

thanks for the reply but I can't seem to find any information on carolbrent or hubbardcnc :( got any links?
