Recently I created a 3D printed “target” holder to help with 2nd laser mirror alignment. This is a much improved “jig”, that now allows to align both mirrors. Continue reading
Some time ago I wrote about Pin table (a.k.a. vector table) I made for my laser cutter. It kind of worked, but I had issue with rivets moving slightly. This caused some issues when cutting/engraving at high speed, as whole work-piece shook. I also wanted to have more pins to hold smaller parts form falling... Continue reading
Recently I had some minor issues with my Shenhui 50W eBay laser machine. Laser beam was not reaching 3rd mirror in the center, so I had to re-align 2nd mirror to make corrections. Normally this is a long and tedious process of moving laser head to different positions, attaching sticky tape, firing laser and then trying to... Continue reading
I have a Prusa i3 Rework 3D printer. Had it for a while, and still learning how to use it. Recently I learned about printing with “support”, so I wanted to share this information. Almost any shape object can be 3d printed, however there are still plenty situation which will test limits of your printer. For example... Continue reading
Today I’ll show you how to level Z-table if you have a laser cutter similar to SH-G350, a.k.a. 50Watt eBay laser machine. My machine came with a z-table that can be raised or lowered manually by rotating a handle. While trying to cut a 1/4″ piece of plywood I noticed that distance from laser head is... Continue reading
If you just doing laser engraving, you don’t really need to worry much about supporting your objects, however when you cutting them, it’s another story. Laser beam slices thru material and continues to whatever lies beneath. If it’s just plain metal table it will reflect back scoring or melting your object from underneath. This is called...
