Magnetic DIY Laser Mount for CR10S and Others

This will print with "Build plate only" supports. You shouldn't need supports everywhere. Links for items I used: [Laser](https://www.amazon.com/Module-Focusable-Printer-Engraving-2500v1/dp/B07BS98YXQ/ref=sr_1_1_sspa?ie=UTF8&qid=1544069006&sr=8-1-spons&keywords=3d%2Bprinter%2Blaser&th=1) I used a 5.5W laser, depending on what you intend to do with it, and you can get away with a smaller one. [Magnets](https://www.amazon.com/gp/product/B077K364Z7/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) Any 3MM x 6MM round magnets will work for this project. [Voltage Regulator](https://www.amazon.com/gp/product/B07BVQ2N7Z/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) You will need a voltage regulator to step the fan output voltage from 12V to 5V for the laser drivers TTL input. I used a L7805CV from this kit. [Nylon Stand-Offs](https://www.amazon.com/NALAKUVARA-Spacers-Stand-off-Accessories-Assortment/dp/B01DD07PTW/ref=sr_1_1_sspa?ie=UTF8&qid=1544069195&sr=8-1-spons&keywords=m3+nylon+standoff&psc=1) I designed the laser driver to be mounted on 6mm Nylon stand-offs, keeping the heat off of the PLA. There is a hole behind the laser driver compartment designed to take air in from the hot end fan. This keeps the laser driver cool without heating up the PLA. You can print with a better material like PETG but it was made to use something easy like PLA. You're welcome. I used stand-offs from this set. [JST Connectors](https://www.amazon.com/gp/product/B071XN7C43/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1) These are to connect the part cooling fan to the TTL port. Setup: After printing the mount, the clearance for the magnets should be tight enough to pressure fit without glue. Use a little force and they will stay. The laser I used, like many others available, uses a 12V input for power, and an optional 5V TTL input for further power level control. I used the extra fan power on the CR-10S motherboard. This laser came with a cable that plugs right in. You will have to extend the cord length a bit. I then used a JST connector to connect the 12V from the part cooling fan to a voltage regulator. I then fed that 5V output into the TTL port on the laser driver. Once this is all setup, you can turn the laser on with your part cooling fan controls. In GCode M106 S### 0-255 controls the power. I use Inkscape with a few plugins. There is a YouTube series linked below. This is where I learned how to use the software.
