I've been gone from LinuxCNC for about 10 yrs. Thought I'd give a try again. And with that I have been working with pi5 GPIOs work fine but thought I might attempt a waveshare pcie adapter and that to the MosChip parallel port card which works in my old PC to run my plasma table.
Where I am at is, LinuxCNC recognizes the MosChip card but shows this error below. Any help would be appreciated.

Note the pcie adapter is from Amazoncnc@raspberrypi:~$ lspci -vv

You _probably_ don't need to take the tachos to LinuxCNC.

Typically the tachos connect only to the servo drives to feed back velocity, and the analogue voltage input from the controller sends a velocity command based on position feedback from the glass scales.

The Leinien FM1 looks like a lovely little thing.

An all-in-one solution from Mesa would be: store.mesanet.com/index.php?route=produc...id=397&search=analog
But there might be cheaper options (for example 6i24 + 7i33TA) but the 7i97T ethernet option will work with just about any supported computer, including the Raspberry Pi.

Other options exist. EtherCAT, Pico PPMC for example.

One of the LinuxCNC developers lives in Münster, I think.

halcmd (and hal)  are fine with true/false for bit types:

pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd setp hm2_7i96s.0.ssr.00.out-00 true
pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd getp hm2_7i96s.0.ssr.00.out-00 TRUE

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found

Likely means that bash was not found.



 

 Sorry, I really didn't comment out these lines in Hal when I tested it from the command line. Here are the error messages.

pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101
' invalid for bitvalue 'True
<commandline>:0: setp failed
: numeric argument required
pi@raspberrypi5:~/linuxcnc/nc_files $ 
 

Tried it two ways, still doesn't work. In the first case it gives an error.

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found
pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101

Hello everyone! This is my first post on the forum. I have a problem with setting up custom M codes on Raspberry + 7i95. I need additional outputs to control the equipment. Just turn on and off some outputs on the 7i95.
In principle, nothing complicated, but when executing custom M code, linuxcnc does not display error messages and the pin states on the 7i95 outputs do not change.
There are no changes in halshow either.

I use this image www.linuxcnc.org/iso/rpi-5-debian-bookwo...25-01-27-0140.img.xz

Here is one of the commands (M101)
#!/bin/bash
halcmd setp hm2_7i95.0.ssr.00.out-01 True
exit 0

Even if you intentionally make a mistake in the M command file, linuxcnc still does not give any error messages.
Has anyone encountered this problem on Rasberry Pi?

I had bought a mini pc from Amazon and I’m not sure if it’s causing latency issues or not ? I’m using a mesa 7i96s .   This is the mini pc I bought.
www.amazon.com/gp/aw/d/B0DNT28BV1?psc=1&...pop_mob_b_asin_title 
i shut every thing i could off in the bios including WiFi. 

I was using probe basic but I get a latency error and random disconnects . 
Could I just switch to a raspberry pi5 16gih version?
