I am running some test cards and have ran into a problem I have not seen before. When engraving circles the engraving goes beyond the edges (at the top of the material), BUT it is still a circle deeper in the engraving. See image.
I would not be the best person to help with the mechanics of a Co2 machine. I only know the basics
However, I know the test above will at least put you in the right directions and might help others help you
Unfortunately my laser did not come with a manual from the factory. I bought it from a dealer here locally. He imports and sells them. He is not a very helpful person. He rarely responds to any of my communications. So I am gonna have to work through this without it.
I did a quick feel check on the belts and all but one feel about right. The drive belt (from the stepper to the pulley shaft) for the X axis was quite loose. I tightened it up. I have not ran another test yet.
Also I did some calibrating my X/Y axes. I was able to get them pretty close. But measuring from corner to corner on some test squares show it is skewed slightly. On a 4"x4" square, it is out .01" corner to corner. Do I correct this by loosening one of the belt pulleys on the drive shaft and turn it slightly and re-tighten? Then re-check?
Gonna do some more testing over the weekend and see what I can figure out.
Here are some pics of my machine. If you happen to have a similar machine and have had similar issues I would appreciate your input.
I agree completely. I had hoped that by purchasing from a local business that has been importing from the same supplier for many years that a lot of these things would have been addressed up front. At least that is what I would do if I was selling them, BUT that was not the case. So I guess I have to go through the entire machine. I could have saved a ton of money ordering from an online dealer but oh well.
YES! I love this idea. I will be keeping this in the back of my mind for a future upgrade for sure.
Especially when you purchase from a business that imports and sells lasers. I realized when I bought mine and he came out to set it up that he does nothing but deliver the laser as it came off the boat without doing any adjusting/calibrating/fixing. Very disappointing. But I guess I am learning more this way
