Hi Khalid,
Would love to see some pictures of your machine that you use this on.

A fan of your work,  Arnie

Well, finished my Tweakie designed PWM to RC ESC converter.  Works great, thanks a lot for your design.  I was able to use your g-code for cutting the circuit board also.

Before installing this I had to stand and watch my machine,  as soon as I got a motor start command with the corresponding beep that signaled my ESC was armed then I would crank the speed control pot on my servo tester.  Pain in the ----.

It has prompted me to dig into programming for these chips.  There are so many things you can do with them.

Tweakie, did you do this in assembly level programming or C ?


No luck there, he never responded.

I did run into a solution that Tweakie built,  http://www.openbuilds.com/threads/software-speed-control-of-a-brushless-dc-bldc-motor-from-mach3.478/  I will probably build it, it looks pretty easy with all the work Tweakie has done to perfect it.

I think there are probably other good solutions out there,  doing this with an Aurdino would be nice also,  especially if you could connect it on USB and use Modbus communication to pass the parameters for the proper RC servo pulse output.
I would try if I knew anything about programming an Aurdino.

You can email me for problems with this.  arnie@wyomingwireless.com

Are you hitting the enter key after putting values in?

I just finished making a oar handle for my raft using lazyturn.  It came out nice.

the last 2 sentences I understood,   I don't understand why you would build it with a rotating table in the center.
Why not just fix your part stationary and move around it with your x & y?

You can use your existing driver cards (if this is the type I am thinking)  the orange and brown wire are step and direction, I forgot which is which.  Black and red are the power lines.  I converted one for the high school here back 8 years ago.  Beware of noise from the spindle DC controller board,  I had to put some small caps on the step and direction lines or every time I ran the spindle the machine would move on its own.

a lot of the breakout boards can be scaled for something less that 10v.  But I don't think it would matter,  you could make a simple voltage divider of 2 resistors of equal resistance across the output of your breakout board and tap into the center for your output to your motor controller.

Not easy to determine with the limited information,  do you have mfg & model of controller? 
I suspect it would be the common on the black wire, and 0-10v+ on the white wire, but can't be positive without more info.
If you have a multimeter measure the black to white as you cycle speed up and down, that will give you further confirmation.
