But the previous sentence is still valid:
The PWM 0-10v Analog output is used for speed control, not for any kind of ramping up to speed.

Well, I respect your opinion but... mk2 has pwm output, mk2/4 not.
And PWM is easier to convert to analog value even without your pricey output board.

I like Mk2/4 board and the CNC-USB SW also...

Well, unluckly the frequency output is a strange choice. I really don't understand why not outputting PWM output directly (my personal view is that it is only a marketing choice).
The frequency...

Mk2/4 boards have a fancy variable frequency output which can be converted in an analog signal (0-10V) or in a PWM signal with a little effort.
Faster way could be using a micro like AtTiny85 that...

Problem is: I have a MK2/4 board. I suppose it is not supported by TNG. Am I wrong?
Unluckly, I bought the MK2/4 board many years ago but I have completed my cnc project only this year!

Hello,
yesterday I was playing with nested while and it seems that only one cycle of the outside loop is executed.
I've also tried to use a simple counter in the outside loop instead of the...

Is there any fix for this bug?

Thank you for the answer.
Now it makes sense, for me, consider also this input in my input/output board (even if I cannot sync the spindle at the moment).

I will answer by myself. I think the only useful application for CTLR8 input is for firmware update.
This leaves me with only two fixed function inputs (IN1 and IN5), plus e-stop (CTRL1).

Please,...
