I think the pdf and BOM are out of sync and want to verify that I'm buying the right thing. I'm looking at the v1 laser BOM rollup, filtered for StockDrive components, and it lists:
X_AXIS_BELT TIMING BELT 0.08 PITCH 36 Stock Drive A 6Z16-C025 $0.25 $9.00
The pricing and length options don't match that on stockdrive, and it doesn't match the part number in the gantry drawing:
http://www.buildlog.net/cnc_laser/drawi ... rev_13.pdf X Axis Belt 1 TIMING BELT 0.08 PITCH STOCK DRIVE A 6R 3-31502
Anyway, I figure the right one is the product from the BOM rollup (A 6Z16-C025) since the pitch matches that of the pulleys. I'm going to get 6 feet, sound right? That's a little more than double the distance between the gantry's pulleys (their distance is 33.4 inches apart).
Thanks
