I recently bought the 2500 and had a real problem with the blade being out of alignment with the mitre slots. Makes me wonder what people do, who buy the saw without the sliding table. Anyway after much crawling under the saw and loosening and tightening and levering (wife helping with lever whilst I tightened)I have now got the blade absolutely parallel, which of course neccessitates resetting the sliding table. which in itself was out of square because the adjustable bearings weren't set right. It would seem that this is a good saw but the fiddling and fettling needed to get the best out of them is quite a task. I spent hours on mine because the setting is hit and miss, it's a question of keep trying until it's right .I made a wooden sled which held a digital vernier to keep measuring off a known good blade.
Just should also say I don't believe this is just a Scheppach problem either.
