Program stops executing after spindle-at-speed reached was created by deemoss
Hi Guys,
I have incorporated the Huanyang VFD via RS485 and can control it and receive feedback, which is a great success for me.
When I run the axis.ngc demo, the program waits for spindle-at-speed to become true (as it should), and then moves the z-axis down (as it should). However, it then stops executing on line 17.
It is interesting, when I comment out the line net spindle-at-speed => spindle.0.at-speed in the my-mill.hal, the program runs ok (albeit not waiting for the spindle to reach its set speed)
I have captured this behaviour, see below:
Why could this be?
Cheers,
Dimos

How long ago did you last push changes into master?
The spindle work has had a few bug fixes pushed.
Though this may be another one to squash...

Thanks Chris,
Following are the spindle related lines:

When did you last pull a new version? I fixed a spindle-at-speed bug on the 8th of October
github.com/LinuxCNC/linuxcnc/commit/eb8d...c5c65be12b6f62ec5141
In fact I fixed that _exact_ bug, as reported here by Rene:
github.com/LinuxCNC/linuxcnc/issues/504
github.com/LinuxCNC/linuxcnc/commit/eb8d...c5c65be12b6f62ec5141

Thanks guys!
Pulled the latest version and the bug is gone!
On another note, with reference to the hal excerpts above, could I consolidate some of the spindle related lines into one or two hal files?
Chees,

Most probably yes. Not sure about the Pyvcp.
