My 7i76e Connection Sheet

You saying, that the needed firmware already on the board?
The standard, which I can use with the schematics from this topic?
(it will be a lathe, step/dir close-loop stepper on ZX and a step/dir close-loop srervo on the spindle + some functions from the schematics)

Yes, the standard firmware will work

The wiring diagram is very helpful!

Simple questions. How to activate TB5 and TB6 outputs? I connected the estop to pin 4 (TB6). LinuxCNC shows error at startup:


24v connected to TB1 (24V - pin 5, GND - pin . 5V connected. One green LED lights up near the RJ45.

Mesa 7i76e is new, ordered from eusurplus.com/

Jumpers: W4, W6 - up, W7, W12 - down.

Attempting to flash the firmware does not change anything

In attachment hal, ini and log files.

Similar problem is described here:

www.cnc-club.ru/forum/viewtopic.php?f=158&t=8544&start=320

The error reffers to an analogue pin, is Mesa set to mode 1 or 2?

Thanks tommy! I corrected config: sserial_port_0 = 20xxxx.

What should the hal file entry look like for the e-stop button to work? Currently no change status when I press the NC button (Lovato LPX C01)


Ok, it's works when I change to hm2_7i76e.0.7i76.0.0.input-03.

E-stop is a digital signal, so no need to use analogue inputs for that.
Sorry if i missed that the first round, i was on the phone.
This is the only thing i add to my configs for simple e-stop control
# --- ESTOP-EXT ---
net estop-ext <= hm2_7i92.0.7i70.1.5.input-23-not
For more complicated things i use e-stop latch
