Kannst du bitte deine .hal und .ini dateien anhängen?

[edit]
ebenso bitte Angaben zu den Motoren, allfälligen Übersetzungen und Spindelsteigungen.

It depends on how the configuration file was created
With a pncconf created hal/ini file , doubling the spindle
OUTPUT_SCALE and related parameters in the .ini
file would be the correct approach.

[SPINDLE_0]
P = 0.0
I = 0.0
D = 0.0
FF0 = 1.0
FF1 = 0.0
FF2 = 0.0
BIAS = 0.0
DEADBAND = 0.0
MAX_OUTPUT = 6000  
OUTPUT_SCALE = 6000
OUTPUT_MIN_LIMIT = 0
OUTPUT_MAX_LIMIT = 6000

 

Hallo
Ich habe mir eine Drehbank gebaut mit Linx-CNC, Version 2.9, als Mesa-Karte verwende ich die 7i96.
Nun habe ich alles über das Hilfsprgramm von der Mesakarte konfiguriert, alles passt bei den Verfahrwegen der Achsen X und Z.
Wenn ich allerdings in Linux CNC die Axis-Oberfläche aufrufe passen die Verfahrwege nicht mehr, wenn in der X-Achse 200 mm zum verfahren eingebe, verfährt er nur 100 mm (mit Zollstock gemessen), bei der DRO Anzeige zeigt er allerdings einen Verfahrweg von 200 mm im Radius  und 400 mm im Durchmesser an.
Ein ähnliches Problem habe ich bei der Z-Achse, gebe ich hier einen Verfahrweg von 200 mm ein verfährt er nur 100 mm.
Kann mir jemand eine Erklärung dafür geben?
Gruß

So how do I fix that?

OK so it appears that the feedback is correct so it sounds
like the PWM scaling is wrong
 

What version of linuxcnc are you using?

This is an example - it only changes the dialog title.

in your config folder there should be a folder named qtvcp/screens/qtdragon
in that folder add this file, rename it qtdragon_handler.py

Erasing/renaming the file will return you to the standard dialog.

 

Copied from the motion man page...



spindle.M.speed-out OUT FLOAT

Desired spindle speed in rotations per minute.

spindle.M.speed-out-abs OUT FLOAT

Desired spindle speed in rotations per minute, always positive regardless of spindle direction.

Mu guess is that your pwm gen doesn't like negative spindle speeds and defaults to 0.

So try to change this line in your hal file....

net spindle-scale-in spindle.0.speed-out => scale.0.in scale.1.in

To this....
net spindle-scale-in spindle.0.speed-out-abs => scale.0.in scale.1.in

I will do the count verification later this afternoon. The encoder is hand made with 100 holes in the ring.
I had to change the sign in the ini file earlier to -100 to get things to work at all.

I downloaded a Tachometer app to my iPhone and it looks like at full speed the spindle is running close to 1000 rpm.

Can you post the code to do this? I've tried various things but my LED pin is not seen (although it shows in HAL monitor as gladevcp.LED1)

Did you verify that you get 100 counts if you rotate the spindle one turn by hand?

Is the scale in the INI file 100? (or -100)

 

That makes sense. I don't think PathPilot uses it for any other duties. I'll change the value to 50 for a 50% duty cycle.

Thank you.

I can't think of anything that I have that would allow me to do that.
I edited the first message to add my ".hal" and ".ini" files.

One thing that seemed weird to me was in pncconf. Even though I had single input 100 line encoder checked, if I go into "calculate scale" it shows 25 line encoder x 4.

So is the encoder scaling wrong? (2x too high)

Is there an independent way to measure the actual spindle RPM?
