I would think some of the reason we are not as popular is that we don't market
ourselves.
Some of it as you said is linuxcnc is more difficult to set up - our saving
grace is our flexibility
and openness.
Another reason is we tend not to cater to what doesn't really matter to machine
control.
eg fully customizable screens.
and also we are developed by people who tend to be engineers first machinists
second.
( don't get upset guys it's not a poke )
We are moving towards making things easier. It is much easier to build a screen
(not just a panel)
now with gladeVCP.
Anyways back to what we were talking about.
Alex would you describe classicladder as a graphical representation of a
scriptable component?
Could we not build a component that does the same thing in your language of
choice?
then you would connect (through HAL) the basic in and out pins and your
scriptable component
could do what ever you like.
I wonder what language is so common or so easy that Joe consumer would not have
the same complaints.
PS
I have no problem looking at MACH for ideas. MACH is not evil. Mach has been
good for the cnc
industry. We have different ideas and goals. If we were trying to make money
you would see our
goals change quite a bit.
I looked a VFD control on MACH briefly. It seems they have a generic modbus
driver and also specific
drivers for VDFs. I may try my hand at making a general modbus component.
