[quote="comjon" post=65945I assume with pwmgen input you are asking me to look for something like pwmgen.0.spindle-speed <= input, but I am not familair enough with Hal syntax to discern..[/quote]

Halmeter lets you look at live values in HAL in real time on a working machine. It's a very useful way to watch what is going on inside HAL.

Note that you can open as many halmeters as you want, all looking at different things.

Halmeter showed 1 for the pwmgen.0.max-dc, therefore I the duty cycle is 100% on that setting.

Attached id my current hal file, short, and not worred about the X,Y,Z axes at the moment.

Thank you.

Just because the PWM is allowed to go to 1, that doesn't mean that it is set to 1. You need to look at the pwmgen.0.value pin to see what duty cycle is being requested. If you see "5000" there, that should be giving full speed at the spindle. (because you have set pwmgen.0.scale to 5000)

You might need to un-comment the line that sets the pwmgen frequency, but the current value (1) is much too low. 50 Hz should work.

Changed the pwm-freq to 50.0, no change. Don't know what to try nexr?.

I can only really help with HAL, You need PCW for the hardware side.

Have you read www.mesanet.com/pdf/adapter/spinx1man.pdf ?

Using Halmeter, when you think that the spindle should be on.

What is the value of the parport pin connected to the Spinx1 "Enable" pin. It needs to be 0 / low / false to enable the SPINX1 (it is active-low)

What is the value of the pwmgen.N.enable pin?

What is the value of the pwmgen.N.value pin?

What is the value of the pwmgen.N.scale parameter?

What is the value of the parport pins connected to the SPINX1 "DIR" pin?

If you open a terminal, type halcmd -kf, then type "show thread" what do you see? Then try "show funct". Paste both outputs here.

you appear to be showing errors in your hal file
and listing pins twice, and the spindle enable is commented out
so this file could never work .

you may also need to invert the spindle enable pin .
try and have it all working without the enable connected ( connect the enable on the spinx to gnd )
then once everything is working then bring the enable pin into play
the enable pin is either at 5v to disable or 0v to enable , if it is the opposite way round you will need to invert the output

CNCBasher,

A "working" hal file is an elusive goal I am (hopefully) achieving in stages. My file currently works with respect to being able to enter M03 S commands and seeing changes in the rpms on the spindle. I ought have clarified that I have been able to "move the needle off zero" so to speak and make some progress.

I understand what you are saying. I am circumventing the typical approach to learning and coding a hal file, and "taking the long way around" to get where I am going.

Thank you for your ongoing support.

parport.1.pin-14.out = TRUE (this is the Enable pin)


The SPINX1 needs the enable pin to be driven low to enable it.

setp parport.1.pin-14.invert-output true

Do you have a link to the spindle drive manual?
