Improved Z Axis for Cyclone PCB Factory
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.

Printing
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.

Hi.
How many steps per mm must be placed on the z axis?
You speak spanish?
My english is not well
Thank you
Hi Manuel,
no I don’t speak spanish.
The step/mm of Z axis is 200, I explain better in the future article where I add all information to set firmware.
Bye Renzo
Ok. Thank you
I have a dremel 300 and it does not fit properly in the fastening piece. Can you hand me the original file to modify it or do you have the modification made for this dremel to pass it to me? Thank you
Hi Manuel,
I add a Dremel 200 holder (already developed but never added) and an original SketchUp file.
But I don’t know if 200 fit wih 300.
Bye tell me if you resolve the problem.
thank you Renzo.
Where is the download?
I add the link in the article.
I’ve tried the stl with the 200 dremel and it’s perfect
Thank you

Hey, hope you are safe and doing well. I had a question, how do you ensure that the rotation of the gears translates into the rotation of the threaded rod. It looks like you are using a normal m8 nut in the larger gear. My larger gear just rotates freely on the threaded rod.
Hi Kaustubh, at minute 6:30 I add a second nut to block the gear.
Bye Renzo
