Re: Wireless MPG's are back in stock

I think the reason he said the price had doubled is that the default price is for the Oak board. Scroll down to get the $239 price for the Acorn board...

Re: Has anyone attempted to install Tower Signal Lights

Thanks @Allin1Chris. As I mentioned this is not urgent for me as a hobbyist, however, it is a great opportunity to learn more about Centroid controls. Thanks to everyone who contributed to this thread.

Re: Acorn CNC 12 and 0-5VDC Voltage following (e.g. Super-PID)-- (SOLVED)

Thanks everyone. I went with the voltage divider (two 4.7k resistors) and that worked great, I am tracking to within just a few rpm across the range of 5000 to 30000.
I hope to do a quick video soon to share.

Re: Acorn CNC 12 and 0-5VDC Voltage following (e.g. Super-PID)-- Anyone?

I used the Voltage Divider Method. I used two 4.7KOhm resistors. seems to do the job nicely.

I'm amazed at hour quiet the SuperPID makes the Dewalt DP611 Router. I can easily have a conversation next to the machine while it runs at 13K- 15K RPM. Beyond that, it gets louder.

Re: Acorn CNC 12 and 0-5VDC Voltage following (e.g. Super-PID)-- Anyone?

Thanks. I figured there might be a trick. I have a question: If I make this change to the PLC Code, does that prevent me from using the Wizard? Right now, I have not yet ventured into the PCL code or Macros; I am only using the wizard. I know there are many things that can be customized but for now ...

Re: Acorn CNC 12 and 0-5VDC Voltage following (e.g. Super-PID)-- Anyone?

From The Super-PID Manual: Options for PC speed control: 1. Super-PID can directly accept a PWM signal from a parallel port, or PWM from a break outboard. 2. Super-PID can directly accept a speed control voltage of 0v to 5v from a break out board or other controller. 3. Super-PID can accept a speed ...

Acorn CNC 12 and 0-5VDC Voltage following (e.g. Super-PID)-- (SOLVED)

I plan to test a Super-PID closed loop router spindle controller with the Centroid Acorn board. (www.SuperPID.com) From what I see, the SuperPID uses a DC voltage to control speed. This can be 0-5 VDC from a control (e.g. Acorn) or a PWM Square wave which teh Super-PID will convert to DC Voltage. Se...

Gary, please do share your process and even your macros, if you are willing.

Re: Has anyone attempted to install Tower Signal Lights

Sounds like a good approach. I reread this thread again and see from the sample code posted, the Oak board software has code for this. So, perhaps I can find a way to make that happen in the Acorn software as well. Looking at the code, it would appear I need to a) create the functions for RedLightOu...

Re: Has anyone attempted to install Tower Signal Lights

Gary, I've not yet ventured into the programming side of the Centroid Control - though I don't mind reading/studying to learn. This is not urgent for me but it seemed like a useful way to get introduced to interfacing. I understand the hardware side of Centroid control and Acorn. Still working aroun...
