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

can you post your config files please?

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:

my-mill.hal
Code:
net spindle-cmd-rpm <= spindle.0.speed-out net spindle-cmd-rpm-abs <= spindle.0.speed-out-abs net spindle-cmd-rps <= spindle.0.speed-out-rps net spindle-cmd-rps-abs <= spindle.0.speed-out-rps-abs net spindle-at-speed => spindle.0.at-speed

custom.hal
Code:
loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyS5 -p none -r 9600 -S 24000 setp vfd.enable 1 net spindle-cmd-rpm-abs => vfd.speed-command net spindle-cw spindle.0.forward => vfd.spindle-forward net spindle-ccw spindle.0.reverse => vfd.spindle-reverse net on

custom_postgui.hal
Code:
loadrt scale loadrt mult2 count=1 addf scale.0 servo-thread addf mult2.0 servo-thread net spindle-at-speed vfd.spindle-at-speed => pyvcp.spindle-at-speed-led net pyvcp-spindle-rpm vfd.spindle-speed-fb => pyvcp.spindle-speed net pyvcp-modbus-ok vfd.hycomm-ok => pyvcp.hycomm-ok # dimos display current and volts setp scale.0.gain 0.1 # divides vfd.ACV by 10 to produce real value # Connect spindle volts to scaler net pyvcp-spindle-voltage-scale vfd.ACV => scale.0.in # Connect scaler output to pyvcp net pyvcp-spindle-voltage scale.0.out => pyvcp.spindle-volts net pyvcp-spindle-amps vfd.OutA => pyvcp.spindle-amps net pyvcp-spindle-voltage => mult2.0.in0 net pyvcp-spindle-amps => mult2.0.in1 net pvcp-spindle-power mult2.0.out => pyvcp.spindle-power

pyvcp_option.hal
Code:
# net spindle-cmd-rpm-abs => pyvcp.spindle-speed # **** force spindle at speed indicator true because we have no feedback **** # net spindle-at-speed => pyvcp.spindle-at-speed-led # sets spindle-at-speed true

Forgot to add, I run version 2.8 pre 1

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

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,
Dimos

Most probably yes. Not sure about the Pyvcp.
