drivers for waveshare RS 485 usb serial converter for huangyang vfd

sudo usermod -a -G dialout $USER

log out, log in

and it's usually a good idea to have rs485 devices grounds connected. it *may* work with just 2 wires, but it's easy to get out of the transceivers common mode voltage range

Thanks, will try tomorrow.

Just to be sure, $USER=$USER or $USER="me" in this case? Or even $USER=$"me"?

$USER is a shell environment variable which will be replaced by the current user name. e.g:

dmitry@nostromo:~$ echo $USER
dmitry
dmitry@nostromo:~$

or you can type your login name instead of $USER

Thanks!

If the tty cannot be opened due to permissions LinuxCNC will not start since the hy_vfd component will fail to start. This is not the case, so permissions on /dev/ttyUSB0 are likely not the culprit.

Please start a terminal, do a 'cd ./linuxcnc/configs/<your configuration>' and start linuxcnc using the command 'linuxcnc <your configuration>.ini'. The terminal will show errors as they occur. Look for something related to hy_vfd
Most likely they are also in linuxcnc_debug.txt or a similar named file (I am not behind a LinuxCNC PC at the moment)

Question to the forum: are there any breaking changes in hy_vfd between LinuxCNC 2.7/Wheezy and LinuxCNC 2.9/Bookworm?

The bits that seem to matter:

@ Bart:
It looks like the stuff about xhc-hb04.tcl may also relate to the high acceleration during homing and jogging, you added slower acceleration for these but I needed to remove something from the pendant from config, will search for this and include.
