Mesa & Modbus

if it can help you this worked on my cnc. now I changed everything.
the type of card does not matter to me. calls to these files and an xor are sufficient.

Here is the final product that worked for me. It was all shamelessly stolen from the posts linked below. The first post is a stepwise command line walkthru of basic connection testing, the second is the configuration I copied and updated for the changes to LCNC and HY_VFD driver. You'll need to comb through it and edit the connections to match your configuration, but this should be a decent roadmap. I've stripped each file down to just the parts relevant to VFD control and display.

Note: The files define far more than basic spindle connection -- there's a glade panel that puts a very nice speed display tab in the Axis GUI. You can use it or not, but you'll have to pick it apart yourself. I barely remember what it took to get to this point, so good luck in the hunt.

Thank you to both of you. I'll get busy, and post again when there is something to update.

It's working!
Thanks for the files guys. The problem ended up being in the main HAL file, but I don't have it narrowed down just yet. I basically disabled a bunch of lines and it's working, and now I need to go through it all line by line and see what can stay and what can go.

If I recall my struggle correctly, it had to do with catching all the changes between the example configurations (older) and the deprecated commands in the newest hy_vfd driver, as well as getting the right motion connection to the driver. This is the last change I made before mine finally worked:

net spindle-speed-cmd motion.spindle-speed-out-abs => spindle-vfd.speed-command
net spindle-vel-cmd-rpm-abs => spindle-vfd.spindle-speed-fb
