I thought of that, but also agree writing that would be a bother.

Thanks Andy.  Take care and stay well.

First I've heard of this, sounds like it could be usefull. ATM I'm 
carving up an e-stop coupling between linuxcnc and a couple of those 3 
phase drives.

Thank you for bringing it to my attention.

What I do is have two separate INI files, which load different
combinations of HAL files.

(Well, in my case it is about 5 different  INI files)

Of course then you are keeping INI files in synch, but you can use
#INCLUDE to keep all the common stuff in the same file.

If you wanted to get really fancy you could have a script that loaded
just enough HAL to read a pin value, then have that load a particular
config, but I am not sure it's worth the bother,

Re: [Emc-users] Need a way to totally disable ALL of B axis stuff in B not plugged in

[Marius Alksnys]

Gene,

how about setting min and max limits to zero (or other initial value), 
maybe also not enabling B drive?

This can be done in a bash script like:
halcmd unlinkp io-board-going-to-b-servo-drive.enable-pin
halcmd setp ini.4.min_limit 0
halcmd setp ini.4.max_limit 0
halcmd setp ini.b.min_limit 0
halcmd setp ini.b.max_limit 0

or in HAL with mux_generic

What I have started is an additional jumper on the home switch that sets
a hal file "net" titled "b-prsnt" true or false according to whether or
not its plugged in.  But this signal is not available at ini file read
time.

What I need is a common way to control whether an include file is loaded
for both the ini and the hal. Two separate files obviously.

I hate the idea of having to keep two configurations in synch with each

Can something like that be cobbled up?

Thank you all.

Re: [Emc-users] Hight Frequency VFD

[Dave Cole]

Siemens used to be quite expensive, but they have really driven down their
prices.

I just saw this:
https://support.industry.siemens.com/forum/WW/en/posts/g120c-for-high-frequency-spindle/212907

So the S120 is the drive to use for high freqs.   I've worked with Yaskawa
drives in the past and the Siemens drives are easier to use.
Plus Siemens phone and website support is really good and free.

[Emc-users] Need a way to totally disable ALL of B axis stuff in B not plugged in

[gene heskett]

Greetings all;

On this 6040 mill. It can be a 3 axis, or a 4 axis, so I would like to 
devise a way to put ALL the B axis stuff in seperate files, but have not 
figured out how to do that to the ini. 

What I have started is an additional jumper on the home switch that sets 
a hal file "net" titled "b-prsnt" true or false according to whether or 
not its plugged in.  But this signal is not available at ini file read 
time.

What I need is a common way to control whether an include file is loaded 
for both the ini and the hal. Two separate files obviously.

I hate the idea of having to keep two configurations in synch with each 
other. One for xyz, and one for xyzb.

Can something like that be cobbled up?

Thank you all.

Cheers, Gene Heskett.
