Laser Carrier and Extractor Duct for the Anycubic Chiron

The laser carrier can be removed without the need to disassemble the hot end and it mounts to the left side of the hotend metal shroud. The laser can easily be detached from the carrier leaving the carrier attached to the hotend shroud

The extractor duct fits 150mm diameter tube and sits on the left side of the Chiron frame

Parts for the carrier
5x 4x8mm thread length countersunk bolts
2x 4mm nuts
3x 3x10mm thread length caphead bolts
1x Male to Female flying lead
1x Voltage Divider (these are easy to make out of vero board, lots of info on the net. My laser pwm is 5v max, so use the appropriate resistors for your laser pwm.) more info in links below

Parts for the extractor duct
11x 4x40mm thread length caphead bolts for the duct
11x 4mm nuts
2x frame mounts (look in links)

Hotend Preparation

Remove the hot end shroud, remove the small pcb, unplub the part cooling fan and install a male to female flying lead. Pass the fan lead and the flying lead though the gap where the pcb goes. Reattach the pcb and install the shroud.

Assembly

Fit the voltage divider into the space on top of the carrier, fit the lid and use two 3x10mm bolts to fix in place.

Place the two 4mm nuts into the nut holder, they are a tight fit, so you might need a vice to seat them.

Remove the 3mm bolt and plug protector from the left side of the hotend shroud. Insert the 3x10mm bolt into the laser carrier and then fit to the the hotend shroud but leave loose. Insert the three 4x8mm bolts, orientate the nut holder with the v cut facing up and tighten all bolts. The upper 4mm bolt is used for location only and does not need a nut.

Fit the laser to the carrier using the two upper holes, 4x8mm countersunk bolts connect the voltage divider output to the laser pwm plug and the input to the part cooling fan flying lead. Connect the voltage supply to the laser.
