I’d like to renew my CNC for PCB, I select a project called Cyclone PCB Factory to start.
But I think there are some issue on the mechanic, so I start to fix they, one of the more important fix is Z Axis for Cyclone to prevent movement when drill the PCB.
I use standard Cyclone system for connection, movement and bearing, but the structure is renewed.
Stepper is a standard Nema17 form factor. I design an holder for 50mm splindle and an holder for a dremel (big).
I advise to print gears with PETG.

Assembling
The Threaded rod have in sequence (from the bottom)
1 bearing B608ZZ already inserted in the structure
1 M8 blocked nut (Bleu)
1 M8 Nut
1 Spring (as other in cyclone PCB)
1 washer
1 M8 Nut
1 M8 blocked nut (Bleu)
1 bearing B608ZZ (inserted in the threaded rod)
Assembly instruction
- First insert bottom bearing then in the threaded rod instert all other quite near.
- Insert the threaded rod in the top (with the other bearing inserted in the rod to the top)
- the insert the rod in the bottom bearing (with the blocked nut about 4 mm inserted)
- Then insert the gear in the top and stop the top blocked nut with a pair of thin pliers then rotate the gears to permit the blocked nut to go near the top bearing.
