I wanted to let you know I’ve modified and printed an extruder carrier for the QU-BD Two-Up printer and heavily modified the file you sent me for the laser mount. Both items have been posted to Thingiverse. The heavy part of the modification was removing all of the extra triangles in the mesh. Sketchup or your STL exporter probably had something to do with that. It was full of holes and duplicate triangles and wouldn’t quite print properly. I tore it down and rebuilt it, then added a support for the fan so it’s more stable and holds the circuit board in tighter.
The modded extruder carrier just has a flat face on it where you can glue the two parts together and end up with a solid piece that pops right on to the X carriage rails. Make another for the extruder and you can easily switch back and forth.
I was also able to come up with a profile in Simplify3D that works well with this printer and laser combination.
Thanks for the help.
Current settings are 50% power moving at 40mm/s.

Upper is pwm with your laser on a smoothie board. Lower is pulsed on-off full power… Works well.. too dark due to my low speed… Gcode from pic laser lite… Thanks works great
