Hi,

my M1 10W has Problems with moving the Laserhead forwards an backwards. Forwards is betted than backwards. It moves very hard. I have greased the rails and it was a little bit betted but it's not good. I think it looks like the spine on the backside is lightly bend. But I don't know if this is normal or new? I hope you can understand what i mean. Maybe you can help me. Thank you very much
