My drivers for some reason rated for 58 volts DC. 2 volts short of the standard power supply which is 60

I am using 48 volt power supply, thinking that any higher voltage may damage the drivers.

Can I use 60 volts DC power supply ?

Thanks

Can you post the hal/ini files made by mesact?
That would help diagnose the issue so mesact can be improved

With a pncconf created file, make sure you set the PWM offset mode true:

setp   [HMOT](CARD0).pwmgen.00.offset-mode 1 # offset mode so 50% = 0

 (for all PWMgens, not just 00)

Also for best ripple/resolution, follow the  PWM guidelines in the 7I97T manual.

Failing to get any results trying to follow the tutorial you posted is the reason I started this thread.
It seems like the drives are not getting 10v analog from the 7i97t.
I tried setting the follow error to 100 and putting my multimeter on the 10v analog on the 7i97t while I am holding the jog button and I get a steady .00v.  

I just tried setting it up with pncconf wizard and now the drives are getting 10v from the 7i97t. They aren’t drifting and they’re responding to jog commands. 

I was going try to edit the mesact derived .Hal files using the new pncconf config as a guide, but they’re just too different for me to feel like I’d succeed.

should I abandon mesact and just focus on pncconfig? I hesitate to go that route since pncconfig doesn’t recognize the board name. I used the discovery option but I’m not sure if I’ll end with it being fully functional or buggy.

Thank you, Peter.

On a locally built (RIP) installation open a terminal and navigate to your linuxcnc installation folder:
then to start glade:
once glade has started, check if the linuxcnc glade widgets have been imported (ie widgets named 'HAL_....')

BIOS settings are important. Have you looked at all the howtos for lowering latency?

La configuración del BIOS es importante. ¿Has visto todos los procedimientos para reducir la latencia?

I'm sorry my Spanish is too poor. The instructions are simple. Try Google translate.

Para instalar desde un Debian 12 nuevo sin LCNC instalado todavía, solo use: sudo dpkg -i (nombre del paquete aquí sin corchetes) para cada deb y reinicie. Elija el kernel RTAI en Grub, disfrute.

Para instalar en Debian 12 con linuxcnc-uspace ya instalado, use: sudo apt purge linuxcnc* y espere a que apt elimine por completo todos los rastros de LCNC.
Luego siga las instrucciones para una nueva instalación de Debian 12 que se indican anteriormente.

I may become a Linuxcnc expert or even a developer in the future. Becoming a developer can be very difficult, but it is not impossible. I especially appreciate the Aciera. It takes a lot of effort and time. I want to be a useful person like him. I think I will work hard and make serious contributions to this forum in the future, I am currently in the learning phase. As a first step, I started making changes to gmoccapy. But there is a problem.
I installed Glade using the sudo apt-get glade command but I think this is a version issue, for example I can't see the jog keys as I should. Can you guide me on this issue? (Don't laugh at me, maybe I can succeed one day on how to become a developer with this inexperience)

I doubled those values from 1100 to 2200 and that seems to work from 100 up to about 1100 rpm. It is off a little more down about 75 rpm but there is less power down there anyway.

Here is 7i96s firmware that adds a stepgen index pin for all stepgens

Note that these have been added to the P1 expansion connector
so can only be used with TTL/5V level index signals. It's also advisable
to add a say 220 Ohm series resistor to each input if interfacing
machine I/O to the P1 FPGA expansion port to protect against negative
input spikes.

 
 

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
