I'm glad you guys know what you're talking about, most days I'm happy if I tie my shoelaces correctly 

Any hoo, I was wondering about shift registers, in that should I use hardware means to clear all outputs? I haven't had a lot to do with them but I understand that the output shift registers can have undefined states at startup and possibly turn on randomly. For the most part probably not an issue but if you are using them for things that shouldn't turn on at startup, tool release, turret clamp, Z Axis brake, spindle gearbox and so on. My friend (Babinda01 on here) has mentioned using a simple resistor/cap combination connected to the shift register clear pin to reset the output registers at power up, which sounds like a good idea instead of burning up a pin from the FPGA.

Also just checking that I can assign ModBus pins for output for a second FPGA and also additional ModBus pins for, well normal Modbus things? My understanding is the ModBus to the second FPGA is just for doing that, and not for adding traditional ModBus devices, so I should design a second "standard" Modbus connection.

Cheers.

Looks like if you buy a Tb 6600 you really don’t know what you get.
I had bought another Tb 6600 and tested it.
Stepper motor much noisier with that new one with the same micro stepping. Outside they look the same but the new ones plastic cover. Last week I cut a large sine and one of the steppers stopped moving so. Lots of material waisted.

So I did run the program again with the torch off same happens at the same place. So I added two 80 mm fans to cool the drivers
Now I can run the programs three times in a row and everything runs fine. So tomorrow I will try to cut the sign. I run them on 2.5 amps . The one for the Z axis runs on 1.5 amps. So I can affirm they are probably reliable for up to 1.5 amps so I am looking for a replacement.

I am considering a Chinese Dm556 or a TMC 2160 How much can they handle in reality?

Does anyone on this Forum use them can they handle 3Amps in reality?

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...
