Ha, I just found them yesterday but I didn't have a chance to look at the specs. I noticed that they were a lot bigger but I was hoping to find that there were smaller sizes available.

http://www.sdp-si.com/web/email/conidrive/ You should consider these belts and pulleys. They are steel reinforced belts. I'm thinking about these as a possible drive upgrade myself*.

*if I can find belts narrow enough and hubs small enough

I was thinking about making a bracket to retain the mounting points on the frame. The hole in the platform will leave space for a 6mm wide belt but it wont be much. The belt would only run one side through the hole and I would make some kind of belt clamp to bolt to the existing holes in the platform. Here is what I came up with for the motor mount.

No need to change the f/w the very nature of stepper motors is they hold in place

Interested to see what you come up with for a design.

I have been thinking about designing a belt drive or possibly a filament drive for the z axis. This would/should eliminate all the banding issues. With a gt2 belt and a 16 tooth pulley that should result in 10micron resolution which is 0.01mm. You can change the firmware to have the z motor not sleep and stay active so the platform is held in place. Anyone tried anything like this?
