Hi all,
Please help me out, as my customers begin to complain:
Since I bought a HX6090 machine I have a problem with the laser beam. I aligned all mirrors to get the beam in the centre of all three mirrors and cutting went well, except that the edge on the left side of the workpiece was always tapered and the right side was perfectly perpendicular.
Last week I went for a cleaning job and removed the lenses. I aligned everything again which took me two days to get all the beams death center again. The focus lens was also removed and everything was cleaned(including the lens holder).
Up to the last mirror and down the tube, everything is fine, but when I put in the lens in the holder, the beam always goes to the left side, which explains the taper! Now it is even this bad that I have to remove the nozzle to get a clean cut.
Does anyone know what is wrong?! Bad lens? Bad horizontal alignment of the tube?
I also want to buy an extra lens holder for different lenses, has the alignment of recent 60Watt+ laser cutters been improved? Does anyone know where to buy these holders and maybe some better alignment mirrors? Ebay doesn't have many and machine suppliers do not seem to be interested...
[edit]
OK, was googling around about lenses, what is the correct orientation of the znse lens? What would the result be if it was upside down?
