First, is the a 7I92M or 7I92TM?
 
This is old machine, so it's probably an old board, so it's probably a 7i92M (sans "T").

Just for future reference, the age of machine will have no bearing on whether it's a T or sans T. It will depend on the period the card was bought. History will show the the Spartan 6 FPGA was hard to get at one stage, hence the switch to the Trion device.

In real life, despite what the "maker community" will tell you, a capacitor isn't the end all and be all. Also you'll really need to know the load current,ripple and frequency for determining the capacitor reqired, which will differ from application to application, just mentioning this as a PSA.
What is the best option is a quality PSU, yep a bench PSU is great for testing, a genuine Meanwell or Weidmüller (depending on where you are not as easy to get hold of and a little more $$$) supply wont let you down once installed, I only mention these as these are the ones I've been using for eons, all DIN rail mount. I usually switch the computer PSU on, then the MESA boards PSUs, then the stepper power and finally the servo driver for the spindle. To tell the truth with all the relays (self latching) and stuff the PSU wiring was way more complicated than maybe what is should have been. But each circuit controlling the mains is independently controlled.
Regarding powering the 7i77/7i776 or any other DB-25 daughter I've been powering mine(7i76/7i74/7i73/7i83)by the DB-25 connector, found it to be a simple and solid solution. The 7i73 & 7i83 are also powered by the smart serial cable via the 7i74.

OK i understand but it is the full HMI and the servo part of the xml. These are the only new things i just added due to the new Servo module i got. I did the same config like it is on page 1 where all others sayed it worked fine for them. What would u need to help?

Probier mal die hier: ekladata.com/pAsj8QbClJezlB3jbgzQV7LEYoA...-Set-User-Manual.pdf

Was du hast ist die Endstufe. Dafür gibt oder braucht es keinen Treiber.


 

Ich habe keine annung uber die Mach3, deise ist die forum fuhr LinuxCNC.
Macht nicht, veiter
Die platine ist ein normale "parallel port card with 3 axis TB6560...." und das funkt problemlos mit LinuxCNC, aber die pins sind niht standard, sind ein totaler mish-mash.
Ich denke ich hab ein config fur die selbe platime, muss morgen im der shop PC gucken.

Thanks for the hint. It is working now, and i can use the index for further actions

Yeah, nice relay/opto isolation is how I have now learned is a way better way to be doing this. Those exact arduino relays are what I use in some of my home IoT projects that I have started months after this CNC was begun.

I've applied some topics I have explored at work that involved signal analysis and curve best fit at 400KHz sample rates and very low voltage and taken some bad conclusions from that in the design of this machine's controls.

My main priority with this post is to confirm that I am not doing something dumb with my ini/hal and that my errors are from voltage latching oddities and not code. I can explain purchases and delays to my wife if I made a mistake, it's a little harder to justify when I only think I have made an error

Thanks for your insight.

5V. GPIO without modification, Mesa default voltage with an inherent 3.3v swing. It's triggering my steppers well doing a 5v to 1.7v swing from high to low. You can see in my configs how I am doing inverted output to get clean steps with sinking vs sourcing. I don't have space in the box for another PSU and the daughter cards, and I am out of time to putz with an ideal solution.

I'm mostly asking if I've done something dumb from a code perspective, and if there is a good way to be more reliable with voltage swing. If my configs are correct I can swap to 5V source and invert my sink/source and be just as voltage tolerant as my step generation.

Professionally I use 3.3v signal logic with a 2.5v swing near amperage's that are an order of magnitude higher than here. I'm a little surprised to see the default as "just go for higher voltage" as my training has more leaned towards isolation being optimal. Again, I am out of my depth on this topic for CNC control so any disagreement or confusion is entirely intended to be constructive and for the purpose of learning.

Hallo,
ich habe mich gerade hier angemeldet weil ich auf eure Hilfe hoffe.
Ich bin recht unerfahren was die Boards für die Fräse angeht.
Also ich habe meine Fräse schon eine ganze Weile und die lief eigentlich. Dann stand sie eine Weile weil mein Projekt beendet war und sie somit nichts zu tun hatte.
Nun wollte ich mal wieder was machen und komischer Weise ging nur noch eine Achse...komisch, aber naja.
Also habe ich mir dieses neue Board gekauft, in der Hoffnung ich brauche an der Verdrahtung und den vorhandenen Anschlüssen, Steckern und Kabeln nicht so viel zu ändern. Es ist mir auch wichtig, das alles auf einem Board ist, also keine extra Driver Module.

Also ich habe mir dieses hier gekauft:
www.amazon.de/Bordstromschalter-%C3%9Cbe...ef_=v_sp_product_dpx

Hier ist ein Foto von dem Board und der CD die ich bekommen habe:
photos.app.goo.gl/hJcqZ8UT4fSkTniS6
photos.app.goo.gl/3wevH6N61yGsL3yE8

Das Problem ist, das auf der CD alles mögliche drauf ist, aber keine Beschreibung zu dem Board welches ich bekommen habe.
Nun weiß ich nicht was ich wo anschließen muss und was ich in Mach3 einstellen muss.
Ich hab ja nun auch keinen Treiben, das ding ist ja per DB25 Port angeschlossen.

Ich hoffe ihr könnt mir da helfen?

Danke
Matthias

 

If you bought the card from Mesa after March 2025, it will already have up-to-date firmware

The firmware is available from Mesa's web store (in the specifications tab of the 7C80)

Hi,
Where can i get the updated firmware?
I have connected the 7C80 to raspberry Pi 5.
Thank you,

Not the same, stat-at-speed looks for two bits in the statusword from the drive.
There is a genuine mistake made there.

But actual speed should work nevertheless, I'll take a look at that also tomorrow.
Do you see any actual speed from the lcec.0 component?

Hi Hakan
thanks for your help , I'm using the cia402pv component you put together, I can't seem to get the drive to feed back the velocity of the motor could this maybe be another issue ?

I seem to have made a mistake in the cia402pv component with the stat-at-speed pin..
I'll look at that tomorrow. If you just want to mill you can comment out the spindle-at-speed signal and
setp Spindle.0.at-speed 1
