usb485 to huanyang vfd

I am setting up another huanyang VFD with a 7i96 and 2.9. I have been following the above and my previous build. So far I can run the "halcmd loadusr" command and the "halcmd spindle enable" and when I use the "halcmd show pin" I can verify that it is true. So I think I am good with the USB to VFD connection. However when I go to open my config I get error on spindle waitpid and then hy_vfd has been exited without becoming ready. Any ideas?

hi
i did also face problems on 2.9 from a recent 2.8 on the vfd
putting everything from the main HAL to a postgui Hal did solve almost all externel invirerment problems
the new interpreter is very triggy on externel in and out signals to the main hal system even on servotread
the postgui seams to be handled mutch more timing friendly as it has been in 2.7.x

Attached is a picture of the error messages, as well as my cusom.hal file and custom_postgui.hal

Last time when I set up the VFD once I has able to run the following (which is just straight copied from the custom.hal file) in the terminal and verify the connection was good, I was able to get axis to load. But this time I can run the following in the terminal just fine. Seems like every other time I plug in my USB it switches between USB0 and USB1, so I have been updating that before I start, just using ls /dev/tty* to verify I am on the correct port. I will post the entire error message next time I try it.

- halcmd loadusr -Wn spindle-vfd hy_vfd -S 24000 -F 400 -n spindle-vfd -t 1 -d /dev/ttyUSB1 -p none -r 19200 -s 1 -g
- halcmd setp spindle-vfd.enable 1
- halcmd show pin

Thanks, I will setup that up. I just haven't super cared until I can get axis to work.

It has been awhile but I finally getting time to work on this again. I am looking through my HAL configuration in axis and if I look in Pins -> motion I don't have any motion.spindle Is this a problem? I believe these are required to run the spindle or at least that is what it required last time I set it up in 2.7.
