spindle turns when energized, should not

Consider the topic closed, gentleman, as I will energize the spindle motor after LinuxCNC starts and begin working towards speed control through the Hal file. Given the absence of PWM hardware (I.e. MESA 5i25) in my setup, I am working with an obsolete architecture and asking of your time that which I ought not. I would like to IRC and with PCW if someone can direct me where to. Thank you.

Linuxcnc can do software pwm, you don't need the mesa card. I'm learning here myself so someone correct me if I'm wrong...

Your stepconf should have all the settings for setting up a basic spindle.

Understood. My setup does not have a VFD.

The Spinx1 as a digital controller for a motor seeking analog input therefore the topic, unless I am mistaken, and should be reposted as such. Please advise on this as I would like this info shared with others trying to resolve a similar issue in future. Thank you.

the problem is not drivng the spinx , linuxcnc can do that just fine ,it is the output to the miniark that you have wrong
wire as if using the spinx as replacing the speed control pot , and not as supplying a voltage .

these are common thyristor based speed controllers used in just about everything , but what they are not is a vfd .
pwm is not a problem with Linuxcnc .

How to supply voltage from the Spinx1, if possible?

PCW hinted at some suggestion, including using a voltage divider, but we did not have time nor were prepared to get into the details.

Any resources or suggestions how I might accomplish my goal are welcome.

I sent you a PM.
If you're wiring this as an electronic pot, you just use sp+,spv and sp- connections. You don't use any external power.
Does your pot currently work such as in turning it ccw the spindle is off, full cw its full on? It should work the same based on the pwm signal it receives from linuxcnc.
The only power you provide is the 5v to the input from the breakout board/ paraport.

I am not sure what a PM is. I looked for an email from you, but have not received anything.

Yes, all I am doing is replacing a POT and yes I am supplying 5v to the Spinx
