Well this seems to be doable, I just don't know if its currently possible
to compile in the machinekit-cnc or lcnc part with the current
machinekit-hal status
(I'm running a cnc router with a machinekit-hal/-cnc combo from november or
so)
Perhaps I should rephrase my question:
What I would like to construct is something like this (where i can specify
the max spindle rpm [12000] in the ini file)
hal.Param('hm2_5i25.0.pwmgen.00.scale').set(c.find('SPINDLE', 'MAXRPM'))
or
hal.Pin('hm2_5i25.0.pwmgen.00.scale').set(c.find('SPINDLE', 'MAXRPM'))
What I have is this:
os.system('halcmd setp hm2_5i25.0.pwmgen.00.scale 12000')
where I would like to replace the hard coded 12000 with a c.find('SPINDLE',
'MAXRPM') construction, that probes it from the .ini file
I just can't figure out how ?
