Hypertherm hsd130 interface

Category: Plasma & Laser

I realize my questions probably don't make much sense so attached are some pics of how I think I should wire it, bypassing the old "phc interface."

I don't want to use the "phc interface" because I would have to make some assumptions about how it was wired.
For example, can I assume the 12v on the on the "phc interface" break out is actually 24v since the hypertherm hsd130 doesn't have 12v?
Do the wire colors correlate to the wire colors in the manual?

If I take the time to verify this, why not just bypass the "phc interface" and go directly to the 37 pin connector that I have documentation for.

Beckhoff AX5YZZ internal probing

Category: EtherCAT

Hello folks...

have anybody working configuration with custom data telegrams of SM pdos which include internal SoE probing objects? I think internal probing in generally over the SoE parameters and S-0-0169, S-0-0170 IDNs ...

@chimeno, @db1981 has some working stuff but I can not see any custom modification of the SMs ifself...

Thanks and regards

(Solved) Initialization code for a rintelligent ECT60 fails when run on an ECR60 was created by kb58

(Solved) Initialization code for a rintelligent ECT60 fails when run on an ECR60

Category: Driver Boards

First post, so be gentle - also, if this is in the wrong sub-forum, feel free to move it.

Back story: I'm building a wire EDM machine based upon Mike Bax's BX18 arc generator. He supplies modified LinuxCNC code, including initialization code for the stepper drivers. It's nearly done but I've run up against a problem with the drivers.

The problem: Mike wrote code for the ECT60 (closed loop driver) version, configuring it to run open-loop steppers. Silly me thought that since they're open loop steppers, there was no reason to spend the extra money on the ECT model, so I bought the ECR (open loop) model. Unfortunately, they're apparently different enough that the ECR gets stuck in the "Pre-Operation" phase during initialization, and neither Mike nor I can figure out why.

We both looked through the XML .ini code and we can't find anything that would cause it to fail. What's a bit concerning however, is that the online manuals are missing at least two sections regarding registers 0x60FE, and 0x6077. It makes me wonder if perhaps more information is missing that could explain why this isn't working.

Obviously the "easy button" is to replace the ECR units with ECT units. I would gladly do so if I had a use for the ECRs, but I do not. Throwing another $200 at this project is a bitter pill - plus I'm stubborn - and I would like to figure this out instead.

Anyone have any ideas?

Note: This is my first interaction with both LinuxCNC (or any form of Linux) and XML, making it much more challenging.

Thanks!

For what I want to do, the script boils down to

echo 2 > /proc/irq/29/smp-affinity

I've tried this and it doesn't work. I get "permission denied" (whether or not I use sudo), presumably because folder irq don't exist. And even if I were to create folder irq, and create a folder 29 within it, I can't see how just creating a file is going to change anything. Something has to use the file, and in this case I think that that something is irqbalance, which as I've mentioned doesn't exist and can't be made to exist.

You might try this script to pin the Ethernet interrupt to the last CPU

Yes, isolcpus is set to 1.

I think that the ping test is a smoking gun.  If the results can be explained and a solution found I suspect (hope?) that everything else will fall into place.  The attached is typical:

File Attachment:

File Name: ping2.txt
File Size:1 KB


It's beyond belief that a round trip that typically takes about 0.1 ms can sometimes take 26ms.  And note that the round trip clearly took more than 1ms quite a few times (the total test took more than the 60027ms it would have taken had there just been one bad ping).  What could possibly be causing this to happen?  It's not as if anything else was going on - apart from the test the computer was essentially idling.

I've paid my $2 Australian and have had a crack at IRQ affinity.  But the solution proposed in the forum piece is of absolutely no use to me.  irqbalance was not even active on my machine, and when I tried to install it it would not activate because the condition "CPUs=>1" was not met.  Which does make sense - if you've only got two CPU's and you're not going to allow interrupts on one of them there isn't much scope for balancing. In practice interrupts are distributed between the two CPU's (note: they are evidently NOT excluded from the isolated CPU).  See the attached file.

 

File Attachment:

File Name: interrupts.txt
File Size:1 KB


Presumably my goal  should be to tie interrupt 29 with CPU 1 and all other interrupts with CPU 0.  But how can this be achieved?  I don't even have a /proc/irq folder, and even if I did I suspect that in the absence of irqbalance creating appropriate files wouldn't do me any good.  And presumably I should also be running the ping test on the isolated CPU.  Does the 99 priority force this to happen, or is something else required?

It's more of a kernel/driver issue than hardware/Linux Distribution issue.

Are you using isolcpus?

The ones on page 9 and 10 only.

The cia402 module will do the right thing with controlword and statusword, you should not need to do anything yourself.
The drive needs to be in OP first.

You can try with 2 ms, I guess. Should work too.

Include all pdo entries even the ones you don't use.

Do I need to configure all pdo entries for all 7 modes? (1600 1A00, 1601 1A01, 1602 etc)

It also says the bits are unique for each operating mode; do I also need to configure the individual bits of Controlword to achieve:
"The servo must be Enabled before it can follow any command. Enable
the servo by turning on bits 1 and 2 of the Controlword (Ready to
Switch On) then turning on bits 0-3 of the Controlword (Operation
Enabled)." 
This is stated multiple times, including page 12, 13, 15 and 26

Setting "sync0Shift=700000" didn't seem to change anything that I can see

Could I just change the configuration to 2ms?

"As I said 2 cores may not be enough anymore"

Why does Microsoft come to mind here? Doubtless the folks at Debian would say that Bookworm is an improvement on Buster, but I'd question how a system that may require more advanced hardware to do exactly the same job can be called an "improvement". I'm quite happy with my little industrial PC. It's a perfect fit for my workshop environment (small, fanless) and experience has proved that it is quite capable of running Linux CNC. So to my mind the problem is not my PC but Bookworm, and if all else fails I'm going to simply revert to the Linux 2.8.2 Buster distribution and accept that my system will have to stand pat as the Debian world moves on. End of rant.

1. yes
2. no
3. wire the power to Mesa, wire step and dir pins from Mesa to drives.
That part is very simple, so start with that and we will help with whatever comes next.

there are a few Intel N100 PC's put there with multi Intel NIC included. Some also have rs485 with terminal input. I would go with that in preference to the Odroid to get away from the realtek card.
