Very frustrating trying to get lasers aimed correctly. The BQ style design with threaded rods has no side to side adjustment. This improved model assembly allows for precise aiming.
This model requires drilling and tapping, but otherwise is a drop in replacement for the traditional mounts.
Threads and holes are a pain with 3D printing. clear and tap hole sizes on traditional charts never seem to work well. In this case, tapping the 3mm holes is a pain. The tap constantly loads up with PLA and must be backed out every few turns and the threads that remain are precarious. If you ruin a hole you can over drill it slightly, fill it with 24 or 5 hour JB Weld, take a mating screw, coat it in Vaseline, the wipe of the Vaseline and thread it into the hole loaded with JB Weld... when it sets up the screw will back out easily because of the Vaseline film and you'll be left with decent threads.
There is also a set of models that can use a piece or wire or an unfolded paperclip for the pivot. This saves tapping, and sourcing another screw. The files for the wire pivot end in "wire."
Prior to any drilling or tapping you should mark the models left and right so you end up having your screw(s) present on the top of the mounting blocks and drill clearance holes in the top bosses and drill/tap threaded holes in the bottom bosses.
btw1 - I added a break off disk to the pivot to keep it steady while printing
btw2 - just uploaded the laser pivot v6 with the set-screw hole now passing into the barrel area. V5 the hole didn't go through. Users would have caught this during pre-drill prior to tapping, but it's better to have the hole pass through.
btw3 - Who are we as a group of users? Yes, the ciclop is open source, but the quality and location of documentation is so poor. It took me many hours over several days to collect drawings or renderings with dimensions (BQ had the best, showing the location of every feature to the nearest 0.1mm) None of the documentation talks about lasers crossing at the center of the platform, although, I suspect we are suppose to move the lasers in or out from center using the threaded rod adjustment. And, using the contraption I designed must change the 30 degree geometry off a bit and effect the accuracy of the scan. There is not one consistent document on lighting... some say create a outside lit photo booth, while others suggest pure darkness. From the way my unit has worked since day one, it obviously needs tweaking to do its best. There are comments about using green lasers for better results and some mention of the Logitech 920 camera for higher resolution. The newbie user is in trouble from day one, just trying to get the Logitech image to show and connect... yet nobody addresses that in their setup videos. (use VLC or Logitech/Microsoft's utilities to prove your camera before trying to get it all up at once in Horus.
This device needs a single repository for all documentation covering all flavors of the design !!!!!!!!! Maybe a wiki that allows anyone to upload?
