Earlier this year I got a low cost CNC router to complement my 3D printing capabilty. The Genmitsu 3018 Pro is a great low cost router with a working volume of 300mm x 180mm x45mm and it also has the option on its controller board to use a PWM output to control a laser module (actually has 2 connector ports). The diameter of the spindle clamp would allow it to use common 30mm x 30mm laser modules without any modification. So, with the addition of a laser module and LaserGRBL software I could do laser engraving and cutting, I'm thinking that will be my Christmas present from Santa this year.
I had an exchange of messages with shabaz and Fred27 about laser safety and decided that before I get my laser module that I should get some safety equipment. Here's what I decided to get.
I took Shabaz's recommendation and got the LS02 Safety Glasses from Edmund Optical. I am going to get a laser in the 450 - 500nm range and these glasses are rated with an Optical Density >7 @ 180 - 532nm.
This particular model fits over my prescription glasses. I like that the working range is marked on the front of the lens.
I'm still looking for a small CO2 extinguisher because the dry chemical ones make too much of a mess. I'll probably need to find an industrial supplier.
I decided to mount a Pan/Tilt IP camera on the ceiling so that I could monitor the laser from the adjacent room on a computer or mobile device. The pan and tilt capability also lets me monitor other activity in the workroom like when I am using the 3D printer. I put presets in the camera for a wide view and also zoomed in views of the CNC router and the 3D printer.
A short video showing the preset views:
The other feature that I've considered is a warning light outside the door of the workroom to indicate that the laser is in operation. That may be overkill for a home setup
