Replied by meister on topic Solving the USB Latency Dogma for HMI/MPG: Technical Feedback Request
I think I need to apologise, I'm currently testing a working serial/USB setup.
Not simple IO, 1kHz loop 3-axis stepper real-time control.
But I can't quite believe it yet, still have a lot to test.

I actually wanted to try building something for the RPI serial port, small and cheap, but for development I have it on the PC with USB/serial, and the bloody thing works.

Norbert,
Was the HAL pin for 'manual tool change confirmation dialog' ever implemented ?
I'm in the process of changing from par ports to mesa 7i92 and moving the PC out of the machine cabinet, as such my keyboard hack for a physical button on the control panel to press the 'Enter' key is no longer practical and with the larger amounts of i/p pins on the mesa card I would like to hook the physical button to a mesa gpio i/p pin and use that to clear the gmoccapy tool change dialog popup

now using 2.9.8 latest build

No because i have no feedback! Its only a dc motor and a disc that rotats in one direction and if you drive backward it looks against a pawl.

Here the mechanism

 


The dc motor drives a planetary gear.. the gear drives a wormgear.. the wormgear rotate the disc where the tools are mounted.


do you have a better solution without any feedback?
its not a issue to drive it to tool one and set it as tool 1.

i had years before mounted a stepper and done it with O Codes.. but the dc motor which was original used is bettee because it hold against the pawl. With stepper there is small small movement on the tool because its not holded against the pawl like the dc motor it does.

dmesg_new looks better.
However, your vid and pid are incorrect.
They are from Stepperonline A6.
You must enter those from your servos.
vid according to manufacturer xml: 00000eff
pid: 0d3e0001 (not sure)

Note:
please use: dmesg | grep ethercat as root
sudo su
password
dmesg | grep ethercat
that's conspicuous
EtherCAT ERROR 0-3: AL status message 0x001A: "Synchronization error".

Are you using the "carousel" component, or any other, or python remap for the tool changer?

Today morning still did not work for me, now evening and it works with Dark Reader active, so try again and let us know if it works.

The forum server is being backed up and upgraded, but for now there are no issues i can see.

set the HOME_search/latch/final velocities to something really, really slow, that way you can see what part of the sequence is causing the issue while homing.

5I20 replacement was created by billykid
Ten years ago I mounted a 5i20 on a friend's lathe. I remember we used all four ports because he wanted to use the original switches for feedrate and other things. Now he'd like a spare board in case of failure. What can I use with four ports?

I flashed back the original firmware to my dongle for testing. When commenting out the assert and adding a debug print there instead if r != 0, I get the following output during jogging in auto:

I tried more than 10 times in a row, and every time the pendant successfully reconnected. In other words, I cannot reproduce your issue. And unfortunately that also means I cannot be of much help to you.

It is a bit surprising that you get the same issue on two different machines, and I don't. Or are the two machines you tested on fairly similar? Could still be e.g. kernel version difference, I suppose. In case they have fixed some usb bugs related to this. It's a bit of a long shot, but I don't have anything better at the moment.

Okay, so probably not hardware related then, after all. I'll try to adjust my test setup a little bit and see if I can reproduce the issue.

Hi PCW,

I have wired this up like you said. When I set the P value to 1000 we have continuous motion that doesnt stop and when I set it to 0 it moves a short while and then stops.

Thanks,

jblanscett
