v2.8.0 - Pin 'motion.spindle-forward' does not exist

Hi guys,

I am trying to control the spindle with rs485 according to these instructions buildyourcnc.com/FAQ/13271 .

However, as I run LinuxCNC I get the error "./custom.hal:10: Pin 'motion.spindle-forward' does not exist". Also, when I execute the halcmd in terminal I get the same error.



Why is this?

I am using 2.8.0 pre 1

The error log is attached.

Thanks!

Ran across the same thing, motion has changed for 2.8

You will need to change all spindle references to spindle.xxx

spindle.forward should fix your particular issue.

Cheers

Thanks racedirector,

I tried the below with no luck. Also should't I see a "spindle" component in the halshow (see screenshot)?

net spindle-cw spindle.0.forward => vfd.spindle-forward
> Pin 'spindle.0.forward' does not exist

and
net spindle-cw halui.spindle.0.forward => vfd.spindle-forward
> Pin 'halui.spindle.0.forward' does not exist





Thanks!

spindle is actually part of motion, take a look at motion in the 2.8 docs, thats how I found it.

Still no joy

dimos@lcnc ~ $ halrun
halcmd: loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
halcmd: net spindle-cmd-rpm-abs => vfd.speed-command
halcmd: net spindle-cw motion.spindle.0.forward => vfd.spindle-forward
<stdin>: Pin 'motion.spindle.0.forward' does not exist

OK it worked when I run lcnc, with the changes applied to custom.hal. Why it didn't work in terminal with halcmd?

I would say because you were still using "motion." "spindle.0.xxx" doesn't use "motion." first.

<stdin>: Pin 'motion.spindle.0.forward' does not exist

if you took the "motion." part off this command it would probably work

You also did not load motion (emcmot)
(you only loaded the VFD module so only VFD pins are available)

AFAIK spindle is still part of motion regardless of any name changes

Thanks racedirector!
