Mesa 7i92 with PC-2-Route Model M2 BOB

This should be close:



 

I am slowly getting back to it ,into mesa first test 2 years ago , where i got very basic success fiddling with the 5abob firmware/linuxcnc 2.8 and some kind of communication with the sl bob relays , that was it .
Now , got pncconf discovery magic to recognise 7i92_slpc2x2d firmware & generate a configuration that , hmm , at least load in linuxcnc . Still a lot do , first will be , charge pump , something is wrong , and or missing.
Learning curve is steep ,i most admit ,the n00b is studying .

Closing linuxcnc get the 7i92 to lock ,red light , reload needed , is that normal ?

Should i specify , as i showed interest in arm64 , I'm on a pc , fresh official debian 12 linuxcnc install ,all up to date to latest ,not messing arround with orange pi 5/rt preempt until i got some success with the x64 .

Yes, when you stop LinuxCNC, the 7I92 watchdog will bite.
The red '/INIT' LED indicates that the watchdog has bitten.
The RED LEDl will go off when you restart LinuxCNC.

Thanks PCW, yes restarting LinuxCNC= all good.


irrelevant here, but ,i fixed links permissions on sl bob pdf i've posted .

  first time i try Ai , it's interesting ...it does look at forum ,tutorial + user manual doc ! i think .
Ease the boring pain (well , let's be optimistic, some may enjoy it) of repetition for you devs/coders repeating; as it's writen in the book ,or solved already there , etc...
but i should come with some questions ,
nothing moved , Ai did not generate working hal  yet  , got to feed the thing with more 
still got pens and papers.

Sorry for my lack of seriousness on the forum , i'll try to stay focus...where was i ,oh, yes 12mhz generator in hal... 

I would generate a configuration with pncconf.
pncconf also knows how to setup a stepgen as
a charge-pump

Ok ,within pncconf , nice , missed that one .

i was reading a post , you did suggest velocity mode as an option .

May i disable charge pump on both BOB ,they got jumpers , test config as is,
just curious , than back to pncconf .

Thanks

Correction , i did enable charge pump in pncconf ...as an output.

That will not work, you must configure stepgen 4 as a charge-pump
(you cannot generate a 12 KHZ signal with an output bit)
