I guess that's the bit I am missing.
In the hal file, there are no "input-a" anything for the X,Y and Z encoders so I don't get how lcnc knows what anything is connected to.

Sorry.

The raw encoder pins have names like:

hm2_7i92.0.encoder.03.input-a
hm2_7i92.0.encoder.03.input-b
hm2_7i92.0.encoder.03.input-index

Thank you for helping. it is working. having some troubles with the WIFI see new work can't connect. What file are recommended for the byte to bot set up with the Parallel Port Raspberry Pi Hat and 5 axis breakout board.

Hi Tim,
your measurements are correct,
the code is wrong

I have fixed the shiftreg plugin,
but the 6.4Mhz of the w5500 are correct,
more is not possible with the ice40up5k on 30Mhz clock.

Thanks !

And that behaviour continues under scurve planner?  That was what I was referring to. Not what standard planner does.

@Joco - my apologies, I completely misunderstood your original warning.  I thought you were concerned that the current TP maybe didn't lock out FH and motion-inhibit as advertised, and perhaps that situation was carried in to Grotius' s-curve TP.

I have not tested the s-curve TP's behavior.

Sorry to all for the unnecessary tangent.

I've failed to work out how to use a spare encoder input on the 7i77 as a Limit switch input.
I've started out by telling PNCConf that the switches are connected to the I/O Field inputs so I can see the syntax, for instance 
net min-x     <=  hm2_7i92.0.7i77.0.0.input-00     for the X limit minus.
Was planning then to edit this line to match an encoder.

But when I study the hal file posted here, I cannot see how the encoder input pins are called. I was expecting there to be similar 7i92..7i77 references in the Joint 0 section for instance and there are for the analogue outputs, but not against the encoders.
Can you help please.
Thanks

Well done!
I will update/patch and try some more codes on my testmachines this evening (living in Germany btw.). I will report back then.

@Julian,

The file seems to run now under -> ./start_axis_9
I removed some segment length checks like : < 1e-12
This is a very tiny value, but it was enough to halt the planner so now and then.
Code is updated.
 

Hello
i have a similar problem. What was the solution ? where connection PUL+ PUL- DIR+ DIR- on the servo drive ?

Hallo, ich habe mal wieder ein paar Detailfragen. Heute der "motor-0-position error"

Mittlerweile läuft meine Maschine unter Probe Basic - ich habe die Werkzeugvermessung unter Dragon einfach nicht hin bekommen. Die Routine von TooTall18T in Version 5(dev.) läuft jetzt auch, der Support von ihm war top.

Folgendes Problem nervt mich gerade: Ich verfahre per Handrad die X Achse, tw mit vollem G0=7,5m/min, das läuft gut, aber beim Bremsen aus Feeds ab 4m/min kommt fast immer der Fehler motor-0-position error. Auf allen Achsen kommt dieser Fehler.
Ich habe 400W Servos von OMC Stepperonline, die autark ihre Rampen steuern, LCNC bekommt davon nichts mit, die sehen für LCNC ja aus wie Stepper. Keine Glasmaßsstäbe/Encoder zusätzlich.

Was ist die Ursache dafür? Muss ich die Beschleunigung rauf oder runterdrehen? Ist jetzt bei 1000. Eigentlich ginge noch mehr.
Ist etwas ganz anderes dafür verantwortlich?

Meine Steplen/stepspace Einstellungen sind bei 2500/2500, die Servos können bis 500kHz am Eingang und wollen mindestens 2 bzw 1 µsec Periode/Pulslänge haben.

Die Latency Tests sind ausreichend  und die Netzwerk Pings auf die Karte ebenfalls. ODer was meint Ihr?
Latency: Servo Jitter 14646, Base Jitter 11328 after 10 minutes. Pings to 10.10.10.10 ~ 0.066-0.081

Noch was: Mein Handrad habe ich etwas gedämpft mit jog-accel Werten von X 0.4 Y 0.25 Z0.2 - hat das evtl eine Auswirkung?

Ich hänge mal meine HAL und INI an.   
Leider kann ich keine Fotos anhängen, obwohl die unter 1MB groß sind.


Vielen Dank fürs Draufgucken und Hinweise! Hanno

Now i have change the entry STEP_SCALE in the *.ini file and the scale in *.hal file but it changes nothing.

Any ideas?

Greetings

Hi everyone
I need some help with ATC.
I used remap m6 Python and need some button to change the tool (M6 TX).
I can't use MDI for some reason
Do you have any thoughts on this?

Your screen shot looks correct. I added multi state labels on the 20th, how are you updating?

Take a look at this thread for the coordination of an external E-Stop with LinuxCNC

I have not tested an external E-Stop so the colors may not stay in sync.
