my first attempt at a rotary union ended up being a bust. i was going to just eat the cost and buy these but something the manufacture said during a response made me pause on that idea. i was told a 2 Kw motor was the requirements to drive one of theirs. my plan was to drive two of these in series so a 4 Kw motor to do this seemed like a deal breaker. so i decided to take another attempt at one. i got tired of looking for a sealing solution from the manufactures that would work with common stock size and trying to find a certain type of seal in the size i needed. So i did what i had to and took matters into my own hands and designed my own and made a mold to cast them myself. so i will either get thing to work or go down swinging trying

Picture, capabilities access denied, that is usually due to not using sudo, so
sudo lspci -v
see if it shows the driver and kernel module.
Always use sudo when dealing with kernel level stuff, for reading only.

Hi,
I do not actually know where to start.

I have 3axis cnc mill set up on Mesa 7i96s with hybrid servo stepper drives 2HSS86H-N

currently when stepper drive goes in to error (position following error) motor stops and is not responding but while cnc control does not go in to e-stop mode.

I would like to have it set up in such a way so in such event as one of the controllers goes in to any fault it will automatically trigger e-stop for the whole control.

Could someone help me set this up?
I need help on very basic level in this field.

Cris.
 

Hi

a. Please guide as how this can be done. Do we need a separate bit file for this. If yes, please share.
-Note that this will only work on stock 7i95t firmware or 7i95t_5abob firmware
-if you disable the stepgens on DB25 pins 4,5 and on.

b. Also how can I generate pwmgen on Pin 1 of the DB25 BoB with 7i95t. Please share instructions / commands.

 

Hallo zusammen

Als absoluter Linux-Anfänger habe ich mir vor ca. 5-6 Jahren mithilfe dieses Forums sowie YouTube-Beiträgen meine erste Konfiguration aufgesetzt und zum Laufen gebracht. Als Screen hatte ich Probe Basic gewählt. Nun habe ich den PC ersetzt, Debian 12 und darauf Linuxcnc 2.9.4 installiert. Als Screen verwende ich wieder Probe Basic. Es funktioniert soweit alles korrekt, bis auf einen Punkt. Nach dem Nullen fährt die Z-Achse nicht auf ihre Nullposition.

 
Die Maschine ist referenziert und steht auf der Parkposition 

 
Danach fahre ich das Werkstück an und nulle alle Achsen

 
Wenn ich dann mit "Go to Zero" die vorher gesetzten Nullpunkte anfahren will, bleibt die z-Achse oben stehen.

Was habe ich übersehen?

MfG Roger 

 
 
 

Thanks Peter, I didn't realise I was to connect field power for this test. I just did, and only get steady yellow lights on CR2 and CR8. No red fault light.
