Hi everyone,

I’m trying to get my XHC-WHB04B-6 wireless handwheel working with LinuxCNC, but mine shows up as:

So the Vendor ID (10ce) is fine, but the Product ID is 0xeb91 instead of the usual 0xeb93.
It’s one of those AliExpress clones, originally meant for EdingCNC controllers.

From what I’ve read, the Product ID is defined in the driver source (like usb.h), and you’d need to rebuild it — which I can’t manage.

Has anyone already patched this or found a way to make LinuxCNC recognize it?

Thanks a lot!
Michael

Ok sorted that out. Now how do I know that linuxcnc is running on the last two cpu's, or, how do I force it to run there?

Your config isolates core 2 & 7.

I read a while back about isolating cores that were on the same die....has something to do with cahe and the like. I really wish I could recall that article.

The G-code is not very different and for the most part should work.

The biggest difference is that you should set a path blending tolerance at the start of the g-code in Linuxcnc. This will be a g-code line something like G64 P0.001 Q0.001.

Other differences will be with sub program calls and O-codes and canned cycles. But unless you are doing parametric g-code (unlikely with CAM produced code) it won't matter.

Linuxcnc's G-code is also similar to a lot of Fanuc code, and with similar exceptions as with Mach3.

I'd either go for mesa or riocore, both types will run on a Spartan 6.

Riocore is pretty good in that it has quite a few mesa doesn't support, has also port for a number of different FGPAs. The only issue is that it needs rebuilding of the driver for each time you change to fpga config. RIO also has a Ethernet plugin that uses a w5500, as of yet no plugin for the Ethernet chip used on the Mesa boards.

Mesa is very very mature, one driver is all that is required for changes to fpga if you keep to the standard mesa set of modules. SmartSerial is a big plus as well.

I built a 7c81/7i90 clone using a spartan 6 dev board and some custom PCBs, mesa & riocore firmware both ran fine on it.

Keep up the good work.

I made some progress on this issue.

The following command will show all open files in Samba which have some form of lock:

smbstatus -L

Edit: Ignore the text below it gave some weird side effects after some more testing.

Adding the following lines to the configuration of the share in smb.conf allows me to overwrite the files even though they are locked.

oplocks = no
level2 oplocks = no
strict locking = no

I'm using Probe Basic and it recently received a "RELOAD PGM" button in the development version which is very welcome.

However it doesn't seem to pick up the changes if I overwrite the file on the share and press the "RELOAD PGM" button. But if I open another file and then open the first file again it picks up the changes right away.

Yes, this is what I am talking about. I attached a picture with a few oil groove patterns among which there are the grooves I am talking about.

I got this result when I ran the checkmask file. I am sure that I don't know how to use isolcpu. I want to isolate two cores with last core being 7.  SO cores 6 and 7 to be used for linuxcnc.

Cores: 8
Actual CPU Mask: ff
Desired CPU Mask: 128
IRQ: 24
Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.1.0-40-rt-amd64 root=UUID=bfdcf9b0-7caa-4c4b-b4c3-585accea347a ro quiet isolcpus=2,7

Hello, I have a few questions.I am building a complete computer with fpga and all other boards, and I have some questions:
1. What firmware should I choose, mesa, remora or, write my own?
2. I want a universal solution, so what input/output boards should I design?
3. Should I design my own case or choose a ready-made one?
Here is one of the prototypes:
-32 outputs 24v 0.5A, 32 inputs 24V, four boards
-4 analog servo -10V.. 10V outputs, 4 encoders input, one board
-Fpga 96 IO board with buffers, one board ()
-Firmware - ported and modified mesa for SPI interface.
-software driver - modified hm2 driver from source code.
-3d printed case.
-Computer Raspberry pi 5 aluminum case

all works fine and stable 
   

I’m just getting started with LinuxCNC and have switched over from Mach4. I’ve been using the Italian ECAM 5 software and would like to continue using it. How different is the G-code between Mach and LinuxCNC? What are the main differences?
