@ Thayloreing Looks like you have no Comms with the board. Which could be why you can't upload the config to the board. Look back in the posts there is steps there to change the IP address for the board to 10.10.10.10.

@scotta, have you tested the v5 boards with CSS ?. I'm having issues only in CSS mode. Signal keeps dropping when there is speed changes during CSS. Voltage newly drops to zero, once speed changes stop it goes to the required speed. I'm thinking it could be the 0-10v chips on the EC500's.

Hi, no sorry have not tested CSS mode. The 0-10v chip is a PWM to analog chip and the Remora code uses the hardware quad timer. With CSS the spindle speed is constantly changing. In the code when the duty cycle changes, the timer is stopped to allow the timer configuration to be updated. This may take long enough for the PWM to analog chip to drop to 0v.

The software PWM module updates the duty cycle on the fly. Running the software PWM module in the base thread may get the PWM frequency in the right ball park.

In my testing of the spindle analogue, I must admit that I never put a scope on the output. Just a multi meter, and that would not have reacted quick enough to see the drop to 0v.

it does adjust the output voltage a bit, but not the scale i dont think.

so here are some numbers when its working

mesa - 5.2v
pwm module - 12.1v in
m3 s12000 (min) - 2.34v in (2.53 unplugged) 4.92v out
m3 s24000 (max) 4.65/5.07(u) 8.62 out

if i step up the input voltage to 14.2v i get 9.77@24k and 5.24@12k

if i adjust the pot on it i can get 10v but only at 14v. i max out at 8.65 @12v. but when i get 10v, im at 5.78 on the low end which i suppose wouldnt be all that bad with an air cooled spindle vs going too slow
