Assembly steps

After getting the materials listed above and printing the parts (0.3 layer height, 250% speed [I have $2 cht nozzle], no supports, PETG or some higher temperature plastic), here are the assembly instructions (please read them all before assembly):

• using a 4mm drill, clear the holes for M3 inserts:

• using the soldering iron, press each of the 6 threaded insert into its hole. Do not press to much, the insert must not exit into the arm hole

• prepare the V -gantry plate, 3 springs,  4 M3 10mm screws and 4 square nuts:

• put the gantry on the printed part and manually insert and rotate one screw from below:

• manually rotate the screw until is about to get above the gantry:

• place a square nut above the screw and rotate it until it catches it

• use a finger to help the nut and screw tighten (continue to manually rotate from bellow):

• repeat for the other 3 screws:

• tighten the screws using an allen key:

• construct the aluminium frame, using the five 100mm bars  as base (horizontal) and the 300mm (vertical). Each  corner fitting uses two T-nuts, two M3 10mm screws and two washers.  
  To act as stopper you can use one M3 16mm screw and a T-nut. Alternative you put one corner fitting on the front of the vertical bar to act as stopper (just one T-nut and one M3 10mm screw with a washer):
   

• insert the carriage onto the vertical bar

• place three M3 10mm screws and three T-nuts at the top of the vertical bar:

• put the springs on the m3 top screws:

• install the lasers modules on the bottom arm (use a screwdriver if necessary):

• insert the wires of the lasers modules into the top channel and drive it inside until it exits in the middle:

• cut the excess wires (be careful not to cut too much):

•  strip the wires and join them by color:

• insert the wires into the micro usb module (the black should go to the GND hole):

• solder the wire to the usb module and the cut the excess:

• using two M3 16mm screws secure the usb module to the arm:

• using a M3 16mm screw and a M3 square nut, secure the soldering iron lower part using the low arm:

• secure the top part of the soldering iron using the high arm (you can use a M3 16mm screw and a M3 square nut if needed). The low arm and the high arm need to be aligned.

• insert the arms into the carriage and use 4 M3 16mm screws to lock it. 

• align and focus the laser beams . The lines should run across the soldering iron and intersect where the tip touches the hole where the theaded insert will be pressed:
   

Result:

• using the the new tool and an M4 heat insert nut, inserts 14 heat insert nuts into the heat insert tip arm:
