Adjustable Z Axis Mod for NEJE 3 (Master 2/2S)

After testing several Z-axis mods downloaded, I thought I'd design my own, with the objective of:

• be as thin as possible
• be lightweight
• be rigid enough to withstand the speed of travel.
• use the existing support on which the laser head is mounted
• allow the use of an eye protection cover screwed on the head

Supplies required

• 2 x M3 brass inserts to be thermo-soldered
• 2 x M3 screws (I used the ones delivered with the engraver)
• 2 x M3 nuts

Assembly of the parts

• Unplug the power cable from the laser engraver
• Unplug the laser head connector
• Unscrew the laser head

1. Main support
   • Put the two M3 nuts in the grooves
   • Attach the main support with two M3 screws and nuts in place of the laser head (we use the original screws that previously held the laser head)
   • Adjust the height at which you want to position the support, check the verticality and finish screwing so that it does not move
2. Laser support
   • Use a soldering iron to place the two brass inserts in the holes provided
   • Slide the support on your laser head N30820 (sand or file a little if necessary)
   • Screw the two M3 screws to hold the laser head
3. Bringing together the 3 parts
   • Put the printed screw into the hole of the main support
   • While holding the laser head, gently turn the knob clockwise so that the screw fits into the laser head support without forcing it

• Replace the laser head connector that you had unplugged at the beginning
• Reconnect the power supply of your Neje engraver

You are done !

Warning: This accessory is not designed for use at very high speeds. Otherwise, the model will need to be redesigned to improve the stability of the head.
