Laser Cutter part2
Progress has gone pretty fast on my new laser cutter. I have put the moving gantry on the frame, and put the frame on a wheeled cart that I made for it. Assembly has been fairly simple, I did run into a problem with the x-axis motor mount. 
The nut inserts are sticking out because the wood piece has been routed too deeply. I removed the inserts and used nuts and bolts instead.
Here are some more pictures:
I moved the cutter onto a new cart. The red horizontal piece is the gantry that moves forwards and backwards.

Here is one of the gold mirrors and it’s mount.
