I set the sprockets vertical with a small level sitting on top of a chain on the sprocket. There is a little bit of play in the gear, so then I set it level with some pressure on the chain towards the sled (sled is removed, counterweights are attached) . I set to zero a few times, and then rotated 360 degrees. It wasn’t coming out perfectly vertical, so then I removed the tension (manually pulling towards the sled) and set it again.
The directions say “If the 'Extend Chain Distance is a multiple of 6.35 mm, there should be a tooth perfectly vertical after extending the chains.”
The left one is coming out as in the picture. The right is almost that far off.
The chain pitch is set to 6.35, the advanced settings are set to default except for extend chain distance which because it is a 12 foot beam is set to 2032 (My beam is raised and after extending x shows a small negative value and y value is coming out at 150 should I lengthen?) Chain length is at 3360 (about 11 feet although my chain is longer, should I change this?)
Any idea why this is not staying at vertical?
