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

thingiverse

After testing several Z Axis mods downloaded from Thingiverse, 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 ! ## Final rendering <iframe width="560" height="315" src="https://www.youtube.com/embed/VcN41pMOOtE" frameborder="0" allowfullscreen></iframe>
