Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Category: Installing LinuxCNC

Brilliant!  I just had GMNOCCAPY up and running for hours without a glitch after making that change.  Believe you nailed it.

Thanks for the great tip.

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Thanks scotta , ini and hal attached.
I played around with the p i d settings today in the INI but it made no difference. Dip in voltage was still there. Also when I set the gain to 0.0025 which should be the correct value for 4000rpm. It doesn't scale right. I need to input 0.02 for it to work.

M19 and spindle-index-enable issues

Category: Advanced Configuration

What makes me wonder is why  constantly forcing index-enable low does not cause a problem for you.
 
You are right. I haven't used G33.1 yet. Will test it soon. 
But from the looks of it, this is not easily solveable --> need to disconnect the index somehow...

EDIT: Could we write a switch component that passes the signal in both directions (similar to mux2 but bidirectional... ) ?

EDIT2: The easiest solution for this is to probably just install a optical sensor as a second index signal... and then use this for indexing in M19 or for G33.1 ?

switching from parport to mesa 7i96 -- check my assumptions

Category: General LinuxCNC Questions

Thank you. I was clearly fantasizing that the mesa card would give me the power of linuxcnc and the ease of deployment of grbl. Silly me. :-)

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

For the spindle 0-10v output there is a PWM to analogue chip on the board. Remora uses hardware PWM to drive that chip. The 0 - 100% SP determines the duty cycle for the PWM.

It would help to share your config files to see what influences the SP on the LinuxCNC side as there is no interactions between the Remora modules, stepgen and PWM, running on the EC500.

Newer versions are not always better.

 

I agree with you. I have several computers running for different tasks (Debian, Ubuntu, OSX, Windows). I work in IT. I just want to test whether I can possibly benefit from version 2.9.4. If it doesn't work, I'll continue to use version 2.8.4.

How to Invert the touchscreen Lenovo Yoga xinput?

Category: General LinuxCNC Questions

Running axis if that matters.

I just flipped my Lenovo Yoga upside down to put the screen at a better viewing angle. Initially the display was upside down, that was easy to correct with Settings | Display | Invert.  So display is now correct

However the touch aspects is still inverted, (touching lower left, shows touch at upper right). How do I go about inverting the touch aspect?

Thanks in advance and much appreciated.

Was kann ich von der alten Konfiguration weiter verwenden, was muss ich anpassen und was muss neu erstellt werden?

Um zurück zur Frage zu kommen würde ich wie schon erwähnt mal probeweise die neue Version auf eine zweite festplatte installieren und deine jetzige Konfiguration mal laden dann kann man auch gleich auf konkrete Fehlermeldungen eingehen.
 

Das habe ich auch so gemacht. Ich habe gerade keinen Zugriff auf die Fehlermeldungen. Es gab aber schon Fehler in der INI Datei.  Daher ja auch die Frage. Ich kann morgen nochmal schauen.
