The homemade PCB router Hightechsystems1 made is impressive. I have 3
questions:
1) Are those motors DC gear motors or stepper motors? They look like DC
Gear motors.
2) Did you have to make any gears for this device?
3) As far as I can see, each axis uses a long worm gear in between two
cylinder beams that keep the drill, etc...moving in a linear direction
(as opposed to rotating with the motor shaft). But I see what looks
like a very low thread on the worm gear cylinder in the center...that
makes me think that there is a different variety of worm gear
techniques/structures. Can somebody describe the gear structure for the
long worm cylinder-movable part?
I was glad to see
https://sdp-si.com/ now has an online catalog with
prices for gears, that is awesome.
thanks
Ted
