I now need to temporarily secure the laser adapter board, this can go on the side of the laser module and can be held in place with Double sided tape. The Neje 30w laser comes with a sliding bracket so any fasteners would have to come from the back, there is a 5mm tapped hole in the bracket and a smaller tapped hole, these are vertical, the holes on my 3D printed mount are horizontal, I had a 5mm Allen head bolt and cut it to size, and just for a trial just mounted the laser using the one bolt, this works fine, I will 3D print a clamp as well and install using the other mounting hole, this will ensure the Laser stays Vertical but the laser is not like a router, there is no pressure so as long as its secured it will be fine, and easy to remove and re-fit the Pen Module.
The first process is to disconnect the drawing machine module at the shield, the connectors are Dupont female connectors, the Positive and Ground are picked up from the 5v supply on the shield and the Pen servo is on Z+, once removed we can put this to one side. Lasers are dangerous and should only be used when wearing the correct Laser safety glasses/goggles, even when carrying out test firing. The machine is currently running on Universal G code sender Platform and at the moment I'm not sure what I need to work the laser, Laser grbl or Lightburn, Lightburn requires a subscription, these are 2 options. The drawing machine is fitted with an Eleksmaker drawing module which works really well, and is easy to fit and remove from the 3D printed mounting block. I want to be able to change between pen and laser fairly easily, and both the laser TTL and Pen servo use the Z+ pin on the shield so it should be pretty straight forward to come up with a switching device(Scratches Head).
My only experience with Lasers is with my Laserpecker Pro which is really good, no laser programs to fathom out, works off the mobile phone but has a size limit of 100mm x 100mm. In this Instructable, I will show you how I Installed a Neje 30W Laser on my Diy grbl drawing machine, the machine is Arduino Uno based with a Grbl CNC Shield.
