Hey guys,
I'm pretty much up and running, except for the spindle control from the software.
I'm using the V1.5 board.
I have the PWM to 0-10v converter board and have it all wired up, but I'm not getting any frequency output.
I discovered your doc on this thread - viewtopic.php?p=41441#p41441
and updated the GRBL firmware as suggested but still no joy.
I know that the rest of it is working because when I use UGS I can use the spindle on command M03 and the it registers that it is turned on, and I can set the speed with Sxxxx and it shows the correct speed on the screen.
However, I wasn't getting any movement. I tested the 0-10V output and noted that I was only getting 0V no matter what the setting.
So I moved to testing the frequency on the PWM output and this is where I noticed that I am getting nothing. There is voltage going through it when I turn the spindle on but no frequency.
A couple of times when I was testing it, a frequency would show up on my meter for about 2-3 seconds and then go back to zero.
Here is a video of me testing the Frequency and voltage with various spindle settings -

So I know that it is partially working because using the M03 and M05 commands makes the voltage go on and off.
The only thing I found which may have been a part of it is in the document you did above. you have
in the actual file the line looks like
With Khz instead of just Hz. I've tried with this set to 2000 as per the original instructions and then again with 2 and then removing 3x0 from line 545.
There appeared to be no difference with either setting.
I'm now drawing a blank and hoping you might know what is going on.
Thanks in advance.

Re: No frequency on PWM for spindle control
Hi,
To wire a PWM->0-10v converter, You have to wire as on the V2.0 board:
input gnd on the converter -> on the PWM S pin on the board
Input PWM on the converter -> on the +5V of the board
