I recently purchased a bosch 4412 and my initial impression was that this was a very well thought out saw. I’ve since run into some issues which have been very disappointing. I would like to mention that I am a cabinet maker and finish carpenter by trade and have been using my saw all day everyday for a week and a half now.
Issue #1: the dust collection design is non-effective. The dust shute does nothing to channel dust away. Not only this but most of the dust ends up on the sliding rails, and subsequently is starting to work itself into the rail housing and bearings. I have seen a significant decline in the smoothness of the sliding action.
Issue #2: there is significant runout apparent on every 5 to 6 cuts (as much as 1/32). Issue #3: I’ve had to realign my fence twice (not counting the initial alignment) in the last week and a half.
Has anyone who has used and /or owns this saw run into similar issues? These issues have been very surprising since most publications have called this the best SCMS on the market right now.
Does anyone with antoher brand slider have similiar issues?

While we don't use that particular saw in our scene shop, we've been using a Delta Sidekick slider, and dust collection is a problem on that saw as well. I'm going to suggest - engineers are welcome to clarify this - that dust collection on a sliding saw is inherently difficult. We have improvised with a collection system that manages to "deflect" the dust into a vent collector, but there is still a lot of airborne material.
The building trades program that our school participates in picked up a 4412 at the begining of the term. I will ask the instructor about how it performs at the job site. His impression (and subsequent reason to purchase) was that this was the best saw for the money. Stay tuned ...
thanks and keep me posted.
