How does the belt connect to the lens carriage?

Postby bdring » Tue Mar 08, 2011 11:09 pm

Are there any photos or drawings of the underside of the laser carriage where the belt is joined? I can't quite figure out this detail and can't see any references to it in the drawings.

Thanks,

Matt.

The belt runs through the t shaped slots in the plate. The belt goes through the long leg of the T. Then a screw is used in the rounded end of the short leg of the T to clamp it to the plate. It does not need to be very tight because the teeth on the belt catch on the head of the screw. Tension on the belt is created by moving the idler bracket. The Y axis works the same on both ends.

FYI: These sheet metal parts are all laser cut...not by me though.

Could not be clearer, thanks! Perhaps a metal cutting machine for the next project, hey :D ?
