Centroid Acorn CNC Basics - Video Series

[ScotY]

My thinking is Marty has a 4 car garage with no cars in it...just filled top to bottom with machinery. It's awesome...wish I had more space. And time. And money.

I will be doing videos on the DMM motors on the Emcoturn 120 lathe. I will try and cover setting up a VFD on Acorn there.
I can do a DC spindle motor with a KBIC-120 DC motor drive equipped with the SI-5 spindle isolator on the bench test rig. Much has to do with time. I may have a couple of paying conversion jobs coming up next week and the holidays are creeping up on us, but I will do what I can!

This jumps ahead a bit but goes over adding an NPN 6 Channel 24VDC Relay output board to Acorn's 6 outputs without relays.
I also discuss using one of the relays on the board to control a MUCH larger relay, like a very large dust collector or vacuum table. Anything over the relay's 10Amp contact rating. Basically use the relay to control a large contactor coil.

Enjoy.

While I tested an inexpensve Chinese "OMRON" Encoder copy, this video does demonstrate setting up an encoder in the Wizard properly.
What to do if your spindle is turing one direction but your encoder says its going in reverse.
Note, its not a good idea to spin an encoder with a drill motor as I do, and this particular encoder needs to be attached to a jackshaft with a flexible coupler, supported on both ends with a bearing. The jackshaft can carry the timing pulley belted at 1:1.

On with the "Show"
