Good evening @tommylight, @unknown (Rob) and @rodw,

Thank you for your helps. I have been working on this. And I have something that is working. 

I have since also purchased the MEAN WELL UHP-750-36 PSU au.mouser.com/ProductDetail/MEAN-WELL/UH...pnvY3grMpLJ29HELBwFs, and have it works with this setup, too.
 
Hi @rodw,

Follows your advice, I have bought the JayCar EMI Filter.

I bought six Earth terminals, while I need only three... The gentleman at the store was not able to to work out that the we don't need bus bar connector to join them, since the DIN rail acts as conductor since the Earth block clamps are metal:

Earth: www.altronics.com.au/p/p2415-dinkle-35a-...w-din-rail-terminal/

They also have DIN Rail fuse holder, too.

I have also last week received a 24VDC contactor from Tropac as you advised. It is a 3-phase one, as you have anticipated.

www.tropac.com.au/10-Pole-24VDC-Coil-5.5...Contactor-LS-Metasol
GMD-12M DC24V 5.5kW 3P Mini Contactor with 1NO Auxiliary Contact

And I have this flyback diode www.jaycar.com.au/diode-fr307-1000v-3a-d027-pack-10/p/ZR1052 to use with it.

I have since learned how to wire it, both switching a router (I used a Dremel grinder) and using the NO terminals to turn on an LED with a 9V battery when coil is turned on.

This is only with the contactor by itself. I have "worked out" how to wire it to the Mesa 7I96S -- but I don't know if it is correct yet.

(
In the process of learning the contactor, I have also learned that some single-phase power tool can't be switched via a contactor, such as this Milwaukee AGV 15-125-XE angle grinder: www.milwaukeetool.com.au/power-tools/met...ers/AGV15-125XE.html, because of start up protection, its manual states:

[
Startup protection:

When switched on, the machine will not start up after voltage breakdown. To continue working, switch the machine off and then on again.
]

So to be able to switch from the Mesa 7I96S, the wood router must not have this protection.
)

Thank you and best regards,

...behai.

 

2.10 or 2.9 will work but you need a recent build.
(newer than 1 month ago)


 

Older versions of LinuxCNC require LAPIC to run, a quick way to check is by editing the GRUB line at boot by adding LAPIC after nosplash.

1- test with no wiring on analog outs
2- analog out and in on drives have polarity, check if correct.
3- 0.3V might be induced from other equipment while measuring, so try setting analog out to 5 or 10V, with drives disconnected or disabled

Seems you would need 2.10 for it to work, see
buildbot.linuxcnc.org
but first try this
buildbot.linuxcnc.org/dists/buster/maste...fd6a133f8b_amd64.deb
download and install with gdebi

i forgot to mention, but pico2 boards are also supported (48 GPIO versions also), how to build for pico2 is in the doc.

small correction , udp2spi is outdated, and the W5500 is controlled directly by the FPGA

!Update!:
Removed the dedicated spindle encoder index pin, now all encoder channels are handling the index pulses. In the project configuration you can now use PIN numbers instead of GPIO numbers,  dedicated chinese breakout board config files and picoBOB-DLX config file. 
You can try it with the Test branch.

i would like to thank your contribution to the project with testing, time and resources to Pubcrawlr and Galetops.

I try man hm2_modbus, command not found as you see in attachment i have linuxcnc 2.9.4, i check in linuxcnc official site this is the last version, i dont know where is the problem 

I presume you are talking about settings in the ini file. Neither unit settings nor pyvcp panel setup should require an .axisrc file.
When you say the display always opens to mm do you mean the number of decimal places?

the device was designed for metal materials. It was tested with other materials and although it works, the precision of the measurement is not satisfactory for me to sign under it as a manufacturer. It works quite well with wood, but a change in structure (a knot in a board) can significantly change the capacitance.

so the answer is: No, the device is designed only for metals.

But I have tried both adding gpio to user and not adding. (They were with fresh image install)
I hav read all that link before writing here but nothing changed.
I am using hal and ini files from another working rpi5. Their user names, file names and locations are same.
If i added hal_gpio to hal file, it gives an error about permission.
I added gpio to user, not worked.
I have created 90-gpio-access file as it described, not worked....
The only thing that I havent tried is SPI... I will try it and write here...

I try man hm2_modbus
and man mesambccc
not exist in my linuxcnc i have the last version 2.9.4 i see in linuxcnc official site this is the last version, if there is newest version tell me please
 

Hi all,I’m running into an issue with my 7i77 analog outputs and could really use some help figuring it out.Setup:

• 7i94 + 7i77 + 7i84
• LinuxCNC with Mesa HAL configuration
• QtDragon GUI

The issue:

• When I set hm2_7i94.0.7i77.0.1.analogena to True, I measure about 0.3V on all +-10V outputs, even without setting any value on an analogout<>.
• When I set a value on one of the analogout<> pins (e.g. analogout2 = 0.1) and leave analogena False, I measure no voltage on the corresponding output.
• What I expected:
  • No voltage at the +-10V outputs just by enabling analogena.
  • A voltage at the specific output only when both analogena is enabled and an analogout<> value is set.

My question:

Is this normal behaviour, or am I missing something in the configuration or wiring? What should I check next to diagnose this?
