you need to count the number of teeth on both the large and the small parts of
the gear, you then multiply all the ratios together
so the final output is 40:1
the next four gears I count 30:10
and on the motor I count 1:12
so 40:1 * 30:10 * 30:10 * 30:10 * 30:10 * 1:12 = 270:1

Woodcutter4, I just now saw this today. Being a newbie to these forums, I’m still trying to figure it all out. I did actually read this one where the motor has been taken apart and have taken mine apart even before reading it. I plan to take it apart again and like you said, do the math. I have the two main motors and the Z motor is on order. I’ll have to see what I get.
You could have made a ‘wiki’ with this 
, Thank you for the support!
Excellent! Thanks!
Sorry I totally dropped the ball on this. Thank you for taking it and running!
Thanks for the work you put in.
Has anyone measured the diameter and thickness of the gears?
What about the diameter, length, and RPM(disconnected from gearbox) of the motor?
Thanks
Out of curiosity, has anybody removed a couple of sets of gears to reduce the ratio?
My Ryobi router doesn’t need that much torque and it sits too long and burns when it needs to move the Z axis…
you can get a different motor with the same bolt pattern.

What’s the “servo type” or connector spec on that? It looks way different than my bridgeport so I want to get the right “kind”…
Ah… I just found that I got mine from Metal Maslow so… I might just be hoping for too much unless I replace the Roybi Router with an actual bearing system. I am running at 100RPM, but… I want even more
Good news is ESTLcam lets you pick a “junk point” for the z movements, so I have it set 1/4" away from the object… I’ll burn scrap wood. It doesn’t look like the carbide upcut from Bar cares; it still looks new.
