How can I "recalibrate" the angle of the swival table, it says it is on 0, but it is 1 degree off. I think the lock on the table is also broken. It will not lock manually on anything, iIt only locks on the designated angles. I was also wondering about the laser. Is there an on/off swtich or when I cut should it come on. If so what might be the reason it is not working. I would really appreciate any help you may be able to provide me. Thank you nwilson1986@yahoo.com
