Hi I do not know the saw you have ,mine is a Proxxon and when it arrived it cut off the centre line .
A quick check showed it was cutting about 5 degrees of centre and the answer was simple .
The top blade holder has a nut on top which was slackened off and the holder turned a few degrees until it cut true .
On your model there will be a adjustment of some sort ,there have to be one .
Hope that helps but remember ,less haste more speed and better cutting .
