Not sure if this is an error in pncconf or somewhere else...

I seem to have a problem where I can't run the servo axis calibration dialog (in AXIS) when I use a config from pncconf. If I use an old config that is from the example configs I can do it fine. If I use the config that I generated with pncconf the dialog comes up empty and I get the following error when I hit the refresh button:
can't read "ininamearray(0)": no such variable
can't read "ininamearray(0)": no such variable
    while executing
"set ininamearray($axisentry)"
    (procedure "iniTuneButtonpress" line 34)
    invoked from within
"iniTuneButtonpress refresh"
    invoked from within
".main.top.fpage0.buttons.refresh invoke"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke]"
    (procedure "tk::ButtonUp" line 22)
    invoked from within
"tk::ButtonUp .main.top.fpage0.buttons.refresh"
    (command bound to event)


I've been working around this by tuning with the old config and copying the values but I was wondering if anyone had a fix for this. This problem showed up in 2.4 and 2.5.0 pre

You might compare the two ini files and spot something different in the pncconf one.

yes this is a bug in pncconf.
I would fix it but I have not figured out exactly what is tripping up axis.
On my todo list.

I'll try to take a look through the config files and see if I can find a critical difference between the one that works and the one that doesn't. I won't be back with the machine until next week though.

I finally figured out what is wrong.
I had pncconf space the setp lines (in the HAL file) to the right to make them easier to read.
The calabration program doesn't like that.
any line that looks similar to this (note the [axis_2] ):

setp pid.z.Pgain [AXIS_2]P

must not start with any spaces,:
I will commit this fix soon.

Thanks Chris!

That seems like more of a bug in Axis than in pncconf. Seems like it should be ignoring the leading whitespace.

Thanks for figuring it out so quickly and thanks pncconf!

Its not Axis either. Axis calls another program for calibration.
I would attempt fixing it but the program is written in TCL.
I find TCL pretty cryptic.

I can't believe it was just spaces !
