Assembly tip, Use a square!
« on: August 06, 2016, 04:18:21 PM »
I just went over my machine with a "square" similar to this one;
https://www.zoro.com/stanley-square-carpenters-steel-12-x-8-in-45-912/i/G1804415/?gclid=CIOKyf70rc4CFQmIfgodU7IEgQ&gclsrc=aw.ds

And I found several issues.
My frame is square, no issue there
My gantry was not square, the beam was tilted and each end was tilted a different direction. loosened up the four bolts and realigned the ends. and made sure the beam was straight up and down. Now the Laser is straight up and down.
My Laser was tilted clockwise. Used the square to set it right.

Now the ends of my circles meet up and there is not a gap in the meeting point of the Squares or round corner squares.

So buy one of these relatively cheap squares and go over your machine. better yet buy a machinist square

The biggest issue was the laser was not straight down. How I found this was during focusing.

Cut a horizontal line then refocused. Cut over the same line and the beam expanded one side of the cut, not both. Do all over again in vertical.

I think this why I have been having such poor cutting performance. It was only out a bit. If you seem to be having poor cutting then you might want check at least your laser is square to your work.
