Is the belt drive system on the Zenbot available?

[coloradonewbie]

I was just looking at the belt drive system on the new Zenbot and was wondering if there is a source for the stepper motor housing or mount setup they are using for the drive belts. It mounts the motor at a 90 degree angle to the surface and covers the pulley and belt I suppose.

They are talking about 800 - 1000 ipm rapids with this table!

If I can build a machine with belts instead of screws and simple mounts like that and also get wicked fast rapids, I'm all for it.

I was watching the YouTube videos on it and it looks really fast. I didn't think belts would be that accurate. Guess I was wrong.

Thanks in advance.

You could buy a motor mount from cncrouterparts.com and adapt it to your purposes. However it looks like they might have a shaft with some bearings on both ends on that machine which would probably be a good idea. It wouldn't be hard to design and you could probably get someone to make them for you pretty cheaply if you can't make them yourself.

Why have super fast rapids on a tiny machine...No sooner has it set off than it has to stop.....

The drive system ie belt drive is so simple to make...just 5 holes and screw it to the front frame...an idler at the rear and it's done...watch for racking when machining at the outer edges.....or fit 2 belts.

need for speed in life is why. IPM looks better then resolution and repeatablity. I will be drag racing my machine too.

I would rather go for increased force and thus acceleration plus better resolution on a smaller table. Maybe cut the rapids in half to 500ipm. That's still better than a lot of people here get by with on larger machines. Mine is 4'x4' and I rapid at 200ipm. My next one I'm aiming for 1000ipm, but that will be more like a 5'x10' table, and I'll have high resolution and acceleration as well due to over-kill surplus servos.
