There are 2 adjusting screws per axis on the print head to adjust the
clearance between bearings and shafts.
Screw in the adjusting screws just until the bearings are still running smoothly
Carbon or metal axles:
2 X ร 8mm length suitable for the printer (for cross kinematics)
2 X ร 4 X 45mm (for the gearbox)
1 tube ร 6 X 20mm (extruder hotend connection via ball bearing)
1 X M6 snap ring (protection against slipping out)
2 Passive heat sink for motor
2 X silent fan 40mm (for hotend and component cooler)
3M thread cutter (cut 3mm threads in the ร 2.6mm holes,
Mount the ball bearing with grub screws and
secure with superglue)
Superglue for screw locking
Cable tie
The gearbox:
Print worm with support
then remove the support and use grinding paste without the motor holder,
assembled on the drilling machine, at high speed.
Then clean and grease well.
Then connect the motor to the worm shaft via the 4/5 mm shaft coupling.
