Hi, no, sorry! We're still in small order production, and spending all resources on OEM sales. It's most likely still too expensive for the usual expectations of DIY'ers because we are not in high production yet, and do not buy cheap bearings. I haven't even had the cost of this one worked up, as it's not a product as shown.
The belting will not go well with molten metal spatter. This one will be the test bed for cutting accuracy and debris management.
All in good time.
Shouldn't show it if I can't sell it, but alas, wanted to show you how it's going!
I will however be pushing for a 4x8 kit to offer at some point. Got a lot of testing to do before that's something I'll stand behind! We're getting closer.
was looking over this, and I thought it was a great idea.... but realized
this would be a cool way to make waycovers for linear tracks and r/p
where can i get the belt material in 1 - 1.5 width with spur gear to drive
it that not super expensive?
Hi Guys,
I'm going to have a booth at the ATX show next week in Anaheim, CA. I would be fun if someone came up to me and said, "hey, I'm from cnczone!" I'll have a bunch of servobelt stages whipping around, all my rotary stages and a servonut stage. C'mon by.
I just put up a vid of a spring reel counterbalance test of a ServoBelt Z axis. works great! The linear force of the spring changes less than the friction of the axis, so it basically stays whereever you put it.

It was done for a large pharmaceutical company. We made both 3 and 5 axis (2X,YY,ZZ). Came out great.
A 22' long servobelt in preliminary testing:

The videos are really cool, I especially like the setup of your 3axis machine.
A few comments, have you tried using a shaft to drive the two parallel axies so you only need one servo for them ?
Secondly in the long axis there is a little "clank" sound whenever it crosses the middle plate - Is that alright ?
Finally did you find the need to machine the mating surfaces between the linear rail and the aluminium extrusion, and the belt assembly and the aluminium extrusion ? I'd imagine it would be pretty hard to mill such a channel in such a long length.
How rigid is the belt compare to rack and pinion?
Thanks, and no, we have not done a shaft across yet. The clank was the bearing blocks going across a splice joint that was not yet perfectly aligned.
No, we do not machine the extrusion for obvious reasons of economy. We're trying to get out of the long machined piece business!
15mgtar:
Of course, not as rigid as metal on metal. I have a stiffness number at the office. I'll get it posted up. It's far stiffer than a conventional belt, which is the point.
Its an isnpiring foruma and I am gonna send the link to my other friends

Hi Guys, been a while since I've posted some ServoBelt stuff.
http://www.youtube.com/belleverman#p/a/u/1/zTeBokV6Iv0
I did a little write up and another vid and pic on this one at mikeeverman.com
Seems like we're shipping different systems every week these days!
question , the alunminum extrustion in the video, which brand is it
not 8020? or bosch?
Yes, it is Bosch. I am constantly amazed at how straight their extrusion is!
The extrusion is 90x180mm heavy. The bearing rails are 20mm.
well I have finally got my plasma table built using drive belts ,using the info from here and there.
I have had great results so far, in fact had to make sure the dti was working properly!
But it was..
have a 1500 x 3600 table, and when running it up and down the full length of the table was getting as low as 0.04mm out.
Am not running linear bearings at all, just plain bearings running on a "C" beam i had ground up.
But i am a true belt convert.!!!
The cuts I an getting are great.
In fact the only thing letting me down at the moment is the Z axis, which is ball screw.
I hope to get some pics sorted out later.
But for those of you wondering if they really can work in real life.....
Yes they do
As to how well they will cope with the dust.. only time will tell.
But at the moment mine are doing great, even with water all over the rails, from the water table.
Hey Mike,
I was looking at your ServoBelt stuff over the weekend and it is very impressive, it makes me want to change my major from Biology to M.E. Anyhow, I was reading a few of your threads and I noticed that people have asked about your products being available to us common CNC hobbyist. Do you have any updates on products and pricing available for us?
First post on this thread but am completely awed by this design. Now I am hoping it will work for my app.
I need to build a machine for making some of my products and want to build it heavy. The spindle could be anything from one of the atc chinese spindles to a 5hp Colombo kit.
The machine is a moving table design with a movement of about 24" on the Y, 60" X and 20" Z. The table will be the Y axis. This should make the weight distribution more even on the X and Y.
I currently carve laminated wood in 3d at 100ipm. I would like to carve much faster than that. Will this belt app work (diy) for a heavy X (200 lbs) and a matching weight on the Y? The Z should be around 75 lbs.
Mike
