In the attachments of this step I included a guide that says which profiles that need to be mounted and where. Before we can compile GRBL, you need to edit some part of the code to make homing (returning to its home position) possible. Hundreds of thousands of Ear Savers have been made already, and millions more have been requested. I wanted the laser not to be in the working area because it would be bad for the laser to be in all those fumes. I've chosen a laser head with movable lens, so you can adjust the Z-distance between the lens and the material you want to cut to set the focal point right. In the pictures of this step, I added some drafts that show you the different views of the frame. I've got a key switch override for the door switch to adjust mirrors. Make two such pairs of thicker sticks. Once you actually start to use the laser itself, be very careful. Important! 7 weeks ago. One button to detect if the cover is closed and another one is the emergency stop. You can use those or buy iron pieces for extra fastness. This can be very harmful to different materials, your skin, and especially your eyes. That way, our stepper motors will need to do 3200 steps per revolution with microsteps instead of 200. (see post 1 year ago). Now the exhaust pipe, the cooling fans for the electronics and the power plug can also be mounted on the backplate. This feature is optional and important for preventing fires (and also helps to make cleaner cuts). Like I said, a work in progress! HOW to make CNC LASER engraver DIY from DVD drive - YouTube For the side panels I used high pressure laminate, just because it looks good and is laser resistant. To assemble the profile, just start by assembling the bottom profiles, then the vertical profiles, the upper ones and last of all the middle profiles. The side panels of my machine are 12 mm. For the last mirror, the one that leads the beam downwards into the lens, I just adjusted the mirror until the beam was perfectly vertical. Four other things that need to be changed are: " #define HOMING_CYCLE_0 (1...Z_AXIS) ", Comment this line. Utilizing a QUIK-LOK arbor for tool-free adjustability as well as laser etched markings and size indicator, users can quickly and easily change sizes without the use of a hex key.
