XHC WHB04B development?

Category: General LinuxCNC Questions

Is it realistic to write a new firmware for the dongle? Is it to improve on the reset?

Sounds like you identified blocking wait states as at least one big part of the problem.
Realistic to rewrite those sections in the component?

fyi, I have the radio version, works well for me needs.

Configure Mesa 7i96s and pktuart with Omron MX2 (wj200)

Category: Advanced Configuration

Thank you Peter, thank you Tom.
I will try to increase the interval.
No pressure with these MX2. I have a running solution with the USB-Dongle.

Thank you !

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

Sorry, I was on mobile, not on PC so I wrongly uploaded platformio.ini. 
I am using SPI2 pins as per your previous suggestions and it was working ok in remora-spi with TMC.
So I am using same for ETH version.
I am uploading actual platformio.ini
 

File Attachment:

File Name: platformio...2-09.ini
File Size:4 KB


Please look at ldscript, which is I have made with reference to already available ldscripts.

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

Hi, 
So you are using the spi1 pins for the w5500? I think this will be a problem if your config uses tmc5160, as the module uses software spi and configure the pins as standard gpio.

If you have time, please watch the video.
Even with a very small P value, the axis starts to oscillate.

Lenovo T14 Gen2 AMD - CRAZY High Latency - Am I screwed?

Category: Computers and Hardware

Like it could be a cooling issue? I guess I can pull the cooler off but the fans are barely spinning and fdoesnt feel warm at all.

Last ditch effort, but not far fetched: repaste the CPU.

I am trying to configure the spindle as a C-axis, but I am having a problem and cannot find a solution.
Could someone please take a look at my configuration and the video and give me some advice?
I was not able to post this in the original lathe thread.

Lenovo T14 Gen2 AMD - CRAZY High Latency - Am I screwed?

Category: Computers and Hardware

Well Ive spent all day trying other installs or live versions and no dice. Cant get any to run live as they just hang at a blank cursor screen. Cant even get anything installed due to a "bad archive mirror" error.

Tried latest regular Debian and got that installed and then followed directions to install linuxcnc and got it up enough to latency test aaaaaand 4,550,000ns....

What causes this so I have some idea what to avoid in the future? What in the hardware would cause this?

socket raw Eth.

Category: Computers and Hardware

We did some tests last year comparing IP network access vs raw packets
with Mesa HostMot2 and the statistical improvement of peak latency  was
minimal so decided it was not worth the effort.

There no issue with root access and LinuxCNC as direct hardware access
requires this and the blocking of normal network traffic on the real time
Ethernet channel also requires root priviledges.

Retrofitting an old industrial CNC Plasma table

Category: Plasmac

thank you for the information Rod. mine has an hpr 130 torch on it and it uses technical gases while cutting, it is dual shielded. the probing happnens from the outer shield on wich the copper consumable touches the table and completes the loop with the ground cable. the wire for probing is connected to the outer shield itself, i can send a picture tomorrow if needed. i'll order two THCAD boards. how would i proceed to connect the one used for probing to the Mesa 7i97T? is it the same as voltage sensing? connected to an encoder input?

The point is that for most configurations you don't deal with pin numbers at all,
just channel numbers, which is also consistent with the hal file function naming.

For GPIO (which is not much used on newer systems) it would be helpful if
pncconf listed the pin numbers at least for parallel port BOBs
