Mesa 7i95T config for workbench tests - to drive H-Bridges + PMDC servos

Category: Configuration Tools

The error is this line:

loadrt hm2_[MESA](BOARD) config=" num_encoders=3 num_pwmgens=3 num_stepgens=0"

Remove it and add the config stanzas to:

loadrt [HM2](DRIVER) board_ip=[HM2](ADDRESS) config="sserial_port_0=00000000 num_encoders=3 num_pwmgens=3"

The 7I95T uses the 7i95 name in hal files so 7i95 hal files will work with 7I95Ts without change.

See the 7i96S manual for inputs, the inputs are isolated from the rest of the board. 7i96S inputs can be used as "switched to ground" or "switched to VCC" so wire them accordingly.
And disconnect the switches from +-5V, normally home/limit switches are powered from VField and usually from 24V as it is better to protect from interference's, but they will also work with 5V.

hm2_eth: discovered 7I95T
while
hm2_7i95: dlopen: /usr/lib/linuxcnc/modules/hm2_7i95.so: cannot open shared object file: No such file or directory
Not sure if the entries in the hal file should also be 7i95T, but it seems so, use the "search and replace" feature in the text editor with CTRL+h and replace every 7i95 with 7i95T, save and run again.

Hello! I try P1. The movement becomes smoother, but still srange. And also srange deaccelerations in traditional tp at moment when movement is smooth and feedrate doesn't change. same programs an non linuxcnc machines works fine. I have such problem on much 3 many years ago. The reason was CPU usage.

Pictures of complete boards, and do motors have any labels?
If not, open one of the connectors and take pictures of the wires inside.

I agree with RotarySMP, it is better to start a new topic.

Mesa 7i95T config for workbench tests - to drive H-Bridges + PMDC servos

Category: Configuration Tools

What makes me curious is mesaflash --device 7i95t --addr 10.10.10.10 --readhmid output, because i can't see TB5 inputs present in the list. Why is that?

Mesa 7i95T config for workbench tests - to drive H-Bridges + PMDC servos

Category: Configuration Tools

My setup i pretty rude, as in photos. Currently no h-bridges connected (have no wires available...) but checking encoders and limit/home switches would be great for me. Actually, even starting without crash would be great:)

Thank you for pointing things out.I did my best and studied the files. I wrote INI and HAL based on initial CT output and config from you Tommy.My linuxcnc is crashing with debug info:
hm2_7i95: dlopen: /usr/lib/linuxcnc/modules/hm2_7i95.so: cannot open shared object file: No such file or directory./main.hal:17: waitpid failed /usr/bin/rtapi_app hm2_7i95./main.hal:17: /usr/bin/rtapi_app exited without becoming ready./main.hal:17: insmod for hm2_7i95 failed, returned -15142Stopping realtime threadsUnloading hal componentsNote: Usid POSIX realtime
Attached HAL, INI and crash report.

The phone number listed is a +41 number, which it apparently the code for Switzerland.

I'm assuming you are somewhere in Europe?

Does that old bandit controller work?

Machine looks pretty good.

Is it a CNC drill press?

What is that induction motor for?

What type of motors does it use?
