Pico Systems has the PPMC, a set of boards to read encoders, drive +-10V velocity servo drives and handle digital I/O. It is fully supported by LinuxCNC. Take a look at: picosystems.store/product-category/analog-servo-interface-ppmc/

You would need :
Mesa 7i96S
Mesa 7i83 for analog out
Mesa 7i85 or 7i85S for encoder feedback
or just a single Mesa 7i97T for everything

Replied by JT on topic FlexGui - View setting error

Today, after update there is this error preventing start. When this entry is present in the .ini file

Code:
[DISPLAY] VIEW = x thats printed in terminal. If i comment that entry, the ui starts [code]  File "/usr/bin/flexgui", line 313, in <module>     window = flexgui()              ^^^^^^^^^   File "/usr/bin/flexgui", line 229, in __init__     startup.setup_jog(self)   File "/usr/lib/python3/dist-packages/libflexgui/startup.py", line 1167, in setup_jog     if parent.jog_increments:        ^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'flexgui' object has no attribute 'jog_increments' Shutting down and cleaning up LinuxCNC... A question about the plotter i was going to ask anyway: If a program is loaded, machine zero is in the center of the plot, and i have to search the preview. Is there a way to have the current coordinate system zero, centered in the plot, to see the preview directly. Thanks for all the work done in this project. At the moment i am integrating the subroutines, and it's really nice how to control the index of tabs and stacked widget with a button connected to some python, then load the program with a push button.   
[/code]
 
I've not figured out how to move the plot in code. I don't get that error so I must have fixed it.

Analog controller for servos was created by Nkbhvid
Hi 
i am retrofitting a 2002 Homag BOF with Rexroth servo motors and ECOdrive BKC xx.3 040 7 FW.
The setup is originally communicating over Sercos I.
my intention was to use the inbuilt analog +-10v and skip the Sercos. I was planning to use the Mesa7i96 through Ethernet and a daughter card than can run analog communication on the 4 axis.
It seems though that Mesa has more or less abandoned their activities in Europe. 
So what are the alternatives to Mesa products?

Help with Wireless Handwheel XHC-WHB04B-6 (wrong Product ID) was created by Gogonfa
Hi everyone,

I’m trying to get my XHC-WHB04B-6 wireless handwheel working with LinuxCNC, but mine shows up as:
Code:
Bus 001 Device 052: ID 10ce:[b]eb91[/b] Silicon Labs

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
