Modbus connection issue mesa 7i76eu pktUART

Category: General LinuxCNC Questions

Hello Bro's;
I m trying to control (read/write ) data from MR-JE mistubishi servo drive using the 7I76EU mesa board, using PKTUART, i could reveive data from mitsubishi HMI but when i tried reading the data from the servo drive, it seems like the connection happened but there is not data reed and when i run the linuxcnc it take time to open not like usual time and two type of error appear as shown on the pic bellow. you will find also the .HAL configuration file and the C file where i put the adresse i wanted to read

whew yes the init light is blinking. I will look into what I need to do to un screw up my card and hopefully get the correct outcome this time lol

M6 shuts off spindle, but no UI confirmation, and program doesn't pause

Category: Basic Configuration

I was reading about g-code remapping again just now. M3 isn't remappable, sadly, but I found that there's an available remap for M6 ("ignore_m6") which would avoid the bug that started this thread. So that's interesting, but not long term, since I might actually want to implement tool changes.

I also found that, while M3 isn't remappable, the S comand is. So there might be a way to use that.

Category: Basic Configuration

G1 Z0 to fool at-speed? Devious! :-) I'll give that a try. M66 is an interesting idea too. I'll think about that.

Right now my solution is all hidden behind a perfectly normal looking M3, which is kind of nice. (Well, unless an M6 happens too quickly after the M3, as I've discovered....)

But first I have to do "just one more test carve" on a piece I want to take on vacation later this week...

LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

ok. i think i got it. you create a bus with width of the data frame, clock the data in/out via SPI, and map each peripheral to a certain bits in the bus to use as input/output control registers. very elegant, simple and lightweight, the only inconvenience it needs driver rebuild for peripherals changes.

compared to mesa which uses memory map with peripherals mapped to addresses in the memory and need cpu parsing to read write addresses. but this allows dynamic configuration of the driver.

Planning to Retrofit a Mazak Integrex200Y Mill-Turn Machine

Category: Advanced Configuration

It wasn't missing it was dryed out during the years and pulled down the battery voltage. Thats the reason the servo amp always complained position lost. I reordered the cap already but you know how it is: Nothing is as permanent as a temporary solution ;)
