3 Achs Fräse mit MESA 7C80 und Raspi 4

Servus strahlensauger.

Ich habe die Endschalter montiert. Es sind Induktive Endschalter an Minimum und Maximum jeder Achse. Das Homing funktioniert (noch) nicht. Ist aber für den Moment auch nicht so wichtig. Viel mehr beschäftigt mich die Spindel, die ich nicht ins Laufen bekomme. Ich habe es über PWM versucht. Aber da rührt sich rein gar nichts.

Hast du mir einen Tipp?

Können Sie Ihre hal an ini-Dateien posten?
 

Hello PCW

As soon as I´m home, I will send the files.

Hello PCW

Here are the files:

  
 

I don't see any obvious issues with the hal /ini files, other than
the facts that the PWM rate was set to 400 Hz which is too low.
It would not prevent the analog output from working,  it would
just cause more output ripple than desired.

What is the voltage between SPINDLE+ and SPINDLE- ?

What is the result of

1. Starting LinuxCNC.

2. Setting the spindle on and the speed to 1/2 of full scale (12000 RPM)

3. Checking all the spindle signals with

halcmd show signal spin

Hello,

Please excuse my crashing into this thread. I've found it very useful so far and managed to set up 6 out of 7 parts of my 30-year-old Gravograph Unica that I'm trying to convert to LinuxCNC running on a Raspberry Pi with a Mesa 7C80.

What's working fine so far are the 3 steppers and corresponding home switches X, Y & Z.

But: The spindle won't turn on.
I'd like to control it via PWM and as far as I can tell there should be PWM output on pin 2 of TB5 of the 7C80.
There's no useable output there, and I'm not sure where to search and what to do next ...

If there's any chance you could have a look at my .hal and .ini files, that would be very much appreciated
I also included the output of the terminal from where LinuxCNC was launched, and the output of "halcmd show signal spin".
Voltage between SINDLE+ and SPINDLE- seems to be just noise or in the mV-Magnitude.

Thank you for reading and best regards,
Erik
