You can temporarily disable homing by setting

NO_FORCE_HOMING = 1
 in all joint sections of the.ini file

That looks OK

Does the spindle speed control work at all. that is,
does MDI command M3 S12000 give you about 12000 RPM
and ~5V output?

Strange behavior Mesa 7i76e - FU YL-620A Speedvoltage

Category: Configuration Tools

Hello,I can't get my spindle with frequency converter YL-620A and Mesa7i76e to rotate. Homing is not working at the moment because the mechanical and electrical components have not yet been connected.
Pin 1 Spindle- to GND
Pin 2 Spindle out to VI1
Pin 3 Spindle+ to 10V
Pin 5 Spindle Ena- to XGND
Pin 6 Spindle Ena+ to FWD
Pin 7 Spindle Dir- to XGND
Pin 8 Spindle Dir+ to REV
In Linuxcnc, I can press the forward, reverse, and stop buttons, and this is also displayed correctly on the frequency converter. When I press the forward button, I measure a fluctuating voltage between approximately 0.65V and 0.9V between pin 2 and pin 1. There is 10V between pin 3 and pin 1. Without starting Linuxcnc, I measure 0V between pin 2 and pin 1. I have already increased the parameter P03.06 and decreased P03.07. Unfortunately, there has been no change.

Spindel über Mesa 7i76e ohne Homing ansteuern

Category: Deutsch

Hallo,
ist es möglich unter Linuxcnc die Spindel (mit FU YL-620A) über eine Mesa 7i76e anzusteuern, ohne die Achsen zu homen? Elektronik und Mechanik sind noch nicht verheiratet. Geht das über Halshow? Wenn ja, wie? Die Spindel läuft über das Poti vom FU problemlos. Habe dann die Parameter für externe Steuerung angepasst... hier hänge ich jetzt fest.

Dank euch

In the editor i just did a mesaflash --device 7i76e --addr 10.10.10.10 --readhmid... there is just TB2/TB3, P1 and P2 visible. No TB4, 5 and 6. Somewhere there the mistake? What to do?

Set GPIOś via Halshow

Category: HAL

Hello,
As a German beginner, I am currently trying to get my Mesa7i76e up and running.
I have connected three relays to pins 17, 18, and 19 and would like to control them via Halshow. When I connect a relay directly to 24V, it activates.
In Halshow, I would say that I have set the correct pins via Set. However, no output is switched. I can switch the yellow indicator in Halshow on and off.
I hope you can help. Thank you.

Probably locale setting issues, so set the locale to en_US and UTF-8 and try again.
sudo dpkg-reconfigure locales

I _think_ that the tabs activate once you press "accept changes" at the bottom?
