Centroid CNC Acorn, CNC4PC C89 +/-10VDC Analog Speed Controller and KBMG-212D DC Brush Controller

Thanks Marty. This is a fantastic amount of information.

Excellent video. I wish I had known about that board 2 years ago. I used a couple of relays and the forward and reverse outputs to swap polarity on my KB board. This method would have been much cleaner.

[@martyscncgarage5275]

It recently came out. I requested something more simple but they added the "kitchen sink" to it. But it DOES work!

[@BillGriggs]

I did have one other question. At around 3:49 in the video you mention and Estop Contactor. I did not see a contactor in this video. Is it something you will add later? I watched the Emco PC5 video and you had a contactor in that box.

[@martyscncgarage5275]

Estop contactor comes when you build the control. I did not use one for this demonstration

[@BillGriggs]

Thanks @@martyscncgarage5275. I thought that was the case but wanted to make sure.

I just found in a box in my garage 4 new static sealed Skyko p 100 step and direction to +/- 10 VDC converters. They were pulled off the market like a 50 MPG carburetor.

Sounds like PWM to analog converters

Can you also use this C89 on an Eding CNC controller? So that the C89 can also work with a Delta asdab2 servo drive as a lathe spindle?

[@martyscncgarage5275]

Check with CNC4PC. I only use Centroid controls.

[@jackdalton1232]

@@martyscncgarage5275 I thought maybe the c89 also works on multiple spindle like vdf and servodrive.. because I'm looking for step/dir speed controller 0-10 volt board that can work on delta servodrives..

[@martyscncgarage5275]

@@jackdalton1232 are you using them as positioning drives/motors? If so, then you want a control like Centroid OAK it maybe able to control your analog drives.

[@jackdalton1232]

@@martyscncgarage5275 no i am using them as lahte spindle. servo motor . servodrive.. i need a 0-10volt pwm converter wich work on my servodrive.. thats all.

[@martyscncgarage5275]

@@jackdalton1232 I believe C89 does this. You should try Centroid Acorn with true spindle encoder input...
