Multiple Mesa 7I84 I/O board setup

Category: General LinuxCNC Questions

Nevermind! I found the correct bin file in the 7I94T manual, 7i94t_ssd.bin. 

Just an FYI when i run pncconf with the Mesa Card 1 option I get an ValueError: Invalid literal for int() with base 10: 'EXPANSION+SERIAL'.

I will try and add the card info to the hal file, should be good practice.

Fast Hole EDM from Hacked Parts

PCW,

Okay, I do not have the board in front of me right now so I can't say for sure, but I have not modified anything on my board so if the jumpers came installed stock then that is how they are now.  Btw, I assume that "jumpers" are just connectors connecting two different points on the board and are used to control the logic, yes? 

And okay, I see what you are saying.  I will plan on testing with the ALRT pined directly into the input (on pin 29).  If I have any issue reading the signal I will revisit this.  

Thank you. 

Now I am going to start trying to put the code together so I can test as soon as I am home. 

Best,
-Dylan

That took care of it!
 removed the existing mesaflash folder since git couldn't clone with an existing folder of the same name, did the sudo make install and was able to right away get the info from the board with mesaflash --device ethernet -addr 192.168.1.121.
Ran the mesaflash --device 7I94T --addr 192.168.1.121 --set ip=10.10.10.11 and I can ping both the 7I96S and the 7I94T through a switch.

Do I need to flash a particular .bin file for the 7I94T and the 7I84s?

Thanks!

Probe Interface Board Design (resistance switching)

Category: Driver Boards

I have 2 simple classic cast iron rectangle precision levels 0.02mm/m (one new made in china and one old made in germany ) the problem is that they lost calibration and are very difficult to use them succesfully in practice.
I have tried the communicating vessels approach and was much easier in practice
cheaper and does not need calibration .
